Hip extensions in squats will focus on the hip extensors themselves. Find out about the muscles for hip extensions in squats with help from a certified personal trainer in this free video clip.
The pushup is one of the more efficient exercises in that it uses multiple joints and, thus, works multiple muscles at the same time. Considered a compound exercise, it works several muscles of the upper body. Changing the position of your hands will cause certain muscles to work harder than others, slightly changing the focus of the exercise.
Squats are often thought of as a thigh-building exercise, but they also heavily recruit your hip muscles. When you squat, you perform what is known as hip extension, or the backward movement of your pelvis. The main muscle activated when you do this is the gluteus maximus, which is your butt muscle. Other muscles involved during hip extension are the hamstrings, a group of four muscles that extend from the back of your thigh up to your rear hips, and the adductor magnus posterior head of your inner thigh and hip regions. It is important you know which muscles are…
Yoga is beneficial for your body, mind and soul. The practice incorporates meditation, breathing techniques and asanas, or poses, which have a variety of benefits such as weight loss, stress reduction and muscle-building. Unlike some strength training exercises that use weights, yoga uses body weight to provide resistance. In addition to regular cardio exercise, you should also include at least two days of strength training into your weekly fitness routine. Fast-paced yoga, such as Vinyasa or Ashtanga, provides cardio and strength training movements.
The deadlift works so many muscle groups it's often classified as a full-body or integrated exercise. Specifically, it focuses on the group of muscles known as the posterior chain -- your glutes, hamstrings, lower back and adductors -- and is the single best exercise for strengthening these muscles, according to strength coach Eric Cressey of Cressey Performance in Boston. Despite its benefits, the deadlift misses a number of muscles.
Punching is actually a great exercise cause it engages a few basic muscle groups at once. Tighten underarm muscles with punching with help from the founder of Exerscribe at the Fit Athletic Club in this free video clip.

Cats are obligate carnivores. They are designed to consume and to process protein-based diets, and their protein must come from meat. The structure of their jaw demonstrates their dietary requirement, in that it has only vertical movement; lateral movement is entirely absent from a cat’s jaw. This structure prevents the cat from grinding grains and vegetable matter. However, cats’ jaws are highly adapted to grasp and to rip the flesh they must consume to survive.
Bicycles are great tools to use when building up muscles all over your body. Find out how to use bicycles to develop your muscles with help from a fitness and nutrition educator in this free video clip.

Women comprise only 14.3 percent of law enforcement personnel across the United States, according to a 2008 police administration study by Charles R. Swanson, Leonard Territo and Robert W. Taylor. The public image of police officers as male and the relatively recent entry of females into law enforcement departments in developed countries create a small pay gap between male and female officers.
Elementary school students learn about the basic building blocks of life by crafting their own cell models. Children better understand cells as a whole system by learning about the functions of each individual cell structure. A cell model project is a hands-on activity where students form real models that help them review the science lessons learned in class. One idea for an animal cell model is to use paper plates and play dough.
The 2CR5 is a lead-free lithium battery model manufactured by a variety of battery companies, including Sanyo, Duracell, Energizer and Panasonic. Designed to be used in cameras, the 2CR5 has a shelf life of more than 10 years. The 2CR5 performs well in extremely hot and cold environments, which is useful when you're taking photographs under a variety of weather conditions.
Although fruit flies are most common in late summer and early fall, they can be a year-round indoor problem if you keep perishable foods on your countertops. The insects are attracted to just about any fruit or vegetable left out to ripen or ferment. From egg to full maturity, fruit flies have a week-long lifespan. Within its short life cycle, however, a single female fruit fly can lay as many as 500 eggs. While prevention is key to keeping this pest out of your kitchen you have several eradication options, of which boric acid isn’t the most effective.
At school science fairs, homemade cell models are almost as ubiquitous as vinegar-and-baking-soda volcanoes. That is for a good reason — they are interesting and fun to make and their creators learn a lot in the process. Three-dimensional (3-D) cell models are frequently made with items found around the home, such as rubber balls, yarn, pasta and breakfast cereal. Although you might have to resort to using some of these items, the majority of cell parts can be created from scratch.
A cell model of an amoeba is a representation of the one-celled organism which has the most basic cell structure of any living being. The amoeba has been studied by science students to understand how multicelled organisms, such as humans, live, operate and reproduce. Recreating a model of this organism helps students not only understand the structure of a cell but demonstrate their knowledge in a tangible, visual manner.
Every cell in every living creature, including the cells in your own body, is made of many tiny parts called organelles. Students usually begin learning about these parts and the structure of cells in middle school. Creating a model of the cell structure of various organisms is a delightful, interactive way to learn about cells. Styrofoam is the perfect medium for creating these models.
Widespread and destructive insects, fruit flies of all species can turn a delicious crop of tangerines into mush. These pests burrow into fruit and produce larvae that destroy the precious pulp inside. Even small infestations can be devastating to commercial production, which relies on fruit free of imperfections, and require swift eradication measures. Home growers of tangerines must also take steps to protect their crops and reduce the potential for the pests to spread.
While you can have a simple compost pile if you live in a rural or semirural area, suburbs and cities typically require some type of enclosure to avoid unsightliness and rodents. Compost enclosures can be made of wood and snow fencing, cinder blocks or a 55-gallon drum with aeration holes. Whatever the materials used, fruit flies can find their way in if they find the fruity kitchen scraps that attract them so.
Most students retain information better when they have hands-on projects to reinforce the information. Having students create a book about the life cycle of the butterfly provides that hands-on reinforcement. Present precise instructions and gentle guidance to keep the children focused on the topic of butterflies for their book.
Cells may be the basic building blocks of life, but they are too small to examine in a typical classroom. This makes the concept abstract and a challenge for students to grasp. A malleable and familiar material such as Playdough makes learning about cells tangible. Cells are comprised of structures called organelles, which are represented with distinct shapes in learning exercises. A different color of Playdough is used to model each organelle.
Plant cells are distinct from animal cells. While their internal organs are similar, plant cells have rigid cell walls which enable tree trunks and plant stems to become stiff and hard. Internally, they have an additional organ known as the chloroplast. The remaining organs are equivalent to those found in animal cells. A model of a plant cell made from jello and fruit can more than adequately depict the appearance and texture of these structures and organs.
A plant cell consists of seven components to include cytoplasm, cell wall, cell membrane, nucleus, mitochondria, vacuole and chloroplast. Each of these components can be made out of edible material, such as Rice Krispies for science projects. Construction of the cell model can be done in a small amount of time and can be displayed and consumed without refrigeration.
Heroes in movies and comic books all have massive chests and bulging muscles that ordinary people don't. Build a muscle body suit from foam rubber that will imitate the look of someone who works out constantly and can probably lift a car with one finger. The project requires supplies from a hardware store and a hobby shop. Just remember that your muscle suit won't fool anyone into thinking those bulging muscles are real.
All cells, which are the basic unit of life, fall into one of two categories: prokaryotic and eukaryotic. The prokaryotic cell is a smaller and less complex type of cell which is associated with bacteria. These cells have no nucleus and no membrane-bound organelles within the cytoplasm. Making a model of a prokaryotic cell is simple and requires just a few items which are available at a hobby store.
While fruit flies are known to be notorious kitchen pests, they can also be grown as a nutritious treat for reptiles. Instead of purchasing fruit flies, you can raise them yourself in a media where they breed and lay eggs. Fruit flies reared for reptiles are wingless, and unlike wild fruit flies, cannot escape to populate your kitchen. Prepare your fruit fly media from ingredients found in your own kitchen.
A 3-D cell project is one of the most common biology class project, but also one of the most complicated ones, as you have to depict accurately all organelles within the cell. Cells are divided into those featuring a nucleus, formally called eukaryotic cells, and those without a nucleus, called prokaryotic. The structure of the two cell types differs greatly, so you must follow a different path to create each type's model. Clay is the most suitable material for this craft, as it is easy to manipulate and produces a long-lasting, sturdy model.
Phytoplankton blooms are communities of microorganisms that flourish in both marine and freshwater environments. The plankton are important food sources for water habitats, but they also hold value as therapeutic agents in skin care products. Skin care products that contain marine phytoplankton claim to alleviate cellulite, rejuvenate skin or act as natural sunscreens. These products are used in professional spas and at home. But at the time of publication, phytoplankton in its natural state, or not blended into a skin care recipe, is only available as a food for aquarium pets.
When you study animal and plant cell composition, it can be helpful to have a model to give you a visual aid of the structure of the cell. Make your own cell model using Jell-O and candy pieces to represent the cell itself and the parts that go inside it. You can even eat your creation after you use it for class. This project is for an animal cell but you could easily alter it for a plant cell as well.
Termiticides are pesticides targeted at termites.These termite population control chemicals can be purchased over the counter, and can be applied to wood or soil. Many termiticides, however, are toxic and non-repellent, making them potentially hazardous to the environment and people.
Humans, and other animals, appear to be a single life-form, but many millions of cells actually make up one person or animal. Inside these tiny cells are even smaller structures, and these minuscule biological structures are the inspiration for an animal cell project.
Evolution is the process by which a species changes and adapts to its environment. While evolution is continually taking place, it typically happens over hundreds or thousands of years, making it not observable in your lifetime. However, some exceptions exist, such as with fruit flies. These small flies have the unique ability to evolve in as little as a few months.
The lemon tree (Citrus limon) ranges to a height of between 10 and 20 feet and normally boasts a collection of sharp thorns hidden among the twigs. While the thorns deter some predators from consuming the fruit, small fruitflies are active on the leaves, sucking away sap and energy.
Sea turtles have a life cycle vastly different from humans. From the nesting phase, to the nursing stage to breeding, the life cycle of a turtle is a subject that can be fascinating to students, especially younger ones. Use a variety of pedagogical activities to teach your students how a turtle is born, grows up and reproduces. Harness the creativity of your students to get them to do projects and activities about a turtle's life cycle that they can be proud of.
Photosynthesis is the process by which plants and animals use sunlight to create energy, both electrical and chemical, in the form of food. Since the process generates oxygen, photosynthesis is the basis of life for nearly all plants and animals. Homeostasis is a living organism's internal balance and how it adjusts in the presence of a changing external environment. Four main factors of photosynthesis can affect homeostasis in a living organism.
Condominiums are generally apartment-style homes that you can buy. Condo community members own the apartment interior and share the common areas with other members. Condo owners have a right to rent the properties as long as renting the condo does not conflict with the terms of the owner's mortgage loan. As a condo owner, you must follow federal fair housing guidelines, whether you rent the property out yourself or with the help of a real estate agent.
The spinal cord is the main message transport system of the body. It's composed of nerve tissue in a bundle that extends from the lower brain down through the spinal column. Nerves branch out from the spinal cord to the various organs of the body. You can conduct a biology or life science project about the spinal cord to learn about this important part of your body.
Apterous fruit flies have evolved to develop to maturity without wings. Originally, these fruit flies were thought to be sterile due to their difficulty breeding and low reproduction rates. In fact, apterous fruit flies are a genetic mutation that occur when two fruit flies carrying the recessive apterous gene mate. Incredible weakness matched with a sluggish demeanor makes these flies unlikely to survive for long outside the confines of a breeding center or lab.
Growing fruit trees that you can eat off of can be very rewarding. Unfortunately plants with edible fruit tend to have more pests than those that don't. Fruit flies are a known nuisance in the produce-filled kitchen, but they can be just as pesky in the garden. There are precious few fruit trees that have any resistance to fruit flies, and most of them are fairly exotic and hard to find in the United States.
The genetic information of an organism is found packaged inside of a membranous compartment of the cell called a nucleus. The structure of the nucleus includes a double outer membrane with channels to the outside called pores; an inner fibrous matrix called nucleoplasm with embedded genetic material, and another smaller compartment called the nucleolus where important structures called ribosomes and ribosomal RNA are made. Most of the time the genetic material in the nucleus is in the form of spaghetti-like chromatin, but when the cell is getting ready to divide, the chromatin condenses into thicker strands called chromosomes.
Prune-eyed fruit flies possess dark, purplish-brown eyes, known as "prune." The prune eye coloring is abnormal for wild fruit flies, which usually possess eyes of different colors. Scientists, particularly geneticists, breed prune-eyed fruit flies to learn how genes work. Fruit flies, also called Drosophila melanogaster, make ideal laboratory animals for geneticists or evolutionary biologists because their average life span is between 26 and 33 days.
Phosphorus occurs naturally in minerals, soil, living organisms and water. Plants depend on phosphorous in the soil to grow and develop properly. Phosphorous aids specifically in ensuring early root development and in accelerating plant maturity. Three forms of phosphorous are typically found in soil: organic, soluble or bound.
A fruit fly is a small, brownish insect that looks like a miniature version of a house fly. Fruit flies tend to gather around rotting fruit, garbage, standing water and decomposing meat. When fruit flies appear, they can get into your food and become a health hazard to you and your family. There are some secrets you can use to kill fruit flies and get them out of your home within a few days of their first appearance.
Science is can be one of the most creative subjects in school. While learning about different types of cells, like plant versus animals, you can be imaginative in how you want to represent them in a model. Using a mix of all the noodles you can find in the kitchen is perfect for representing all of the different parts that make up an animal cell.
Building a plant or animal cell replica is a project found in both primary and secondary science education. This task can be difficult for some students because of the high number of unique names. Make the project more interesting for students by using cake and candy for visual aids. Use the age and maturity level of the group of students to help guide the complexity of the project. To help promote creativity as well as home participation, assign this as a take-home project for older students.
Fruit flies are active in the summer, but you won't find them in cold winter temperatures. The tiny pests will find their way into your home in warm months, hovering around exposed fruit and food wherever they can find it -- even pet food may not be safe. However, in temperate regions, fruit flies won't be a problem for at least half the year.
Aloe plants are often grown indoors. Aloe is a succulent plant with large, fluid-filled leaves. These leaves are prone to insect infestations, especially when damaged. Fruit flies are attracted to recently injured aloe plants or are otherwise failing in health. Keeping your aloe healthy makes it less inviting to pests.
African dwarf frog is a catch-all name for frogs that are scientifically classified in the genus Hymenochirus. This genus includes five species of small frogs that are native to regions of Africa that include the Congo and Zaire. African dwarf frogs generally grow to 2 inches in length and depending on the species, have a life span of 5 to 18 years.
Organisms get their energy from an organelle in their cells known as the mitochondrion, often dubbed the cell's powerhouse. The production of energy within the mitochondria involves a series of chemical processes. One of the main processes is the Krebs cycle. In the Krebs cycle, acetyl, a fat derivative, is converted into ATP (the energy molecule) and other products that release energy. The Krebs cycle is the second of three processes that convert simple sugar into energy and otherwise power the cell. To understand the Krebs cycle, you must know what chemicals are involved in each step of the cycle…
