Human cell structure is identical to any other animal cell. Each cell has common structures that allow it to function as it was intended, having the instructions located in the nucleus. Not all...

Stem cells have the capacity to many develop into different cell types. Some types of stem cells, called pluripotent stem cells, can become any type of cell in the body. Research into stem cells...

When speaking about cell balance, it is common to run into the term "homeostasis." A cell must maintain homeostasis, literally a permanent condition where everything remains the same. For a cell,...

A load cell is a transducer that converts an axial force input into a voltage signal that is proportional to the magnitude of the input force. The load cell circuit in the majority of load cells...

The idea of using the sun to generate a home's electricity has been the dream of many for years. Technological advances in the last decade have greatly improved the efficiency and pe- watt cost...

All living cells are protected by their cellular membrane which is made up of proteins and phospholipids. The structure of the cell membrane is very specific and not only protects the cell and the...

Solar panels convert the energy of light into electricity that can be consumed by residential, commercial, or industrial customers. Solar panels take advantage of the photoelectric effect to...

Tissue culturing is an important advancement in biological research that allowed investigators to analyze the growth, development and function of cells. To carry out tissue culturing effectively,...

Button batteries, also known as button cell batteries, are small, flat, round batteries designed for use in wristwatches, pocket calculators, hearing aids, cameras, TV remote controls and other...

While most active during bone growth, osteoprogenitor cells reactivate to repair bone fractures in adults and may become osteoblast cells during bone remodeling. From stem cells to progenitor...

The cell is the basic unit of life. All human beings are made of cells. Although they are incredibly small, cells are also extremely complex. Human cells perform specialized functions and...

The cell is the smallest living unit. While all living things contain at least one cell, higher organisms contain a multitude of these components. In the human body, for example, there are around...

The science of microbiology has its roots in a very simple fact; All life is built on cells. This seemingly small detail is the main principle of cell theory, which has allowed scientists to study...

Technically, cloning is simply the creation of an identical copy of something. However, the term is most commonly used in reference to the copying of biological material or entire organisms. ...

Each type of cell has a set life span and when blood cells die, replacements must take their place. White blood cells only survive for a few days, platelets can last 10 days and red blood cells...

Epithelia are membranous tissues, usually in a single layer, but not always. They form the covering of most internal surfaces and organs as well as the outer surface of an animal's body....

A number of arguments can be made for and against the prospect of stem cell research. Most of these arguments revolve around the ethics of using embryos for the research and treatment of diseases....

Saccharomyces cerevisiae is a unicellular fungus commonly known as yeast. This species of yeast is baker's yeast; it is important in the baking and brewing industries. However, this yeast displays...

Cell theory developed as a result of early observations under the microscope. Cell theory has three basic generalizations, according to the University of California at Davis. These generalizations...

All cells must divide to reproduce. In large, complex organisms, such as mammals, cells divide and die in a cycle that keeps the tissues of the organism rejuvenated. The process is called the cell...

New cells are produced by cell division. The two new cells produced when a cell divides are called daughter cells. When two daughter cells have the same number of chromosomes as the original cell,...

Muscle cells are designed primarily to allow movement of different parts of your body. This include both the external and internal parts of your body. One of the important internal organ movements...

Although the process is called cellular respiration (CR), cells do not actually "breathe" as organisms do. Instead, they take in a supply of nutrients that they use for energy, and release...

A solar cell is a device that converts sunlight into energy via a phenomenon called the photoelectric effect. Discovered in the 19th century, solar cells have undergone great advancements in the...

Embryonic stem cell research has been a topic of great debate. Stem cells are unspecialized cells that have the ability to become whatever type of cell is needed. This makes them crucial to humans...

Digestion is the process that turns chunks of food into small sugars, amino acids, fatty acids and nucleotide components. These small molecules are used by all the cells in the body to make new...

In criminal cases, DNA fingerprinting is used to link DNA evidence with a particular person. DNA is essentially a blueprint of our genetic information contained within our cells. Even skin cells...

The practice of cloning has been around since the 1970s within the field of molecular biology. Scientific experimentation has always been viewed as a reliable means of understanding how the...
