phagotrophy the method by which some organisms or cells acquire nutrition, using pseudopodia to engulf their prey or other particles ...
Stoma, which are bordered by guard cells that regulate the size of the opening, function in gas exchange between the plant and the external environment. The stomatal apparatus or stomate consists of the stoma plus guard cells.
Contaminants pass through the placenta and can affect the way basic cells of organs, the nervous system and other bodily functions separate or develop. Contaminants can affect brain, organ and immune system development as children grow and mature.
This is why wounds must be cleaned to prevent these organisms from living off the damaged cells of the wound and causing it to become septic or infected.
Since electricity is produced by a chemical reaction and not by combustion, fuel cells are considered to be green power producers. Fuel cell technology is quite old, dating back to the early days of the space program.
Nanosolar's Martin Roscheisen says CIGS-based cells are flexible and more durable, making them easier to install in a wide range of applications.
In some poisonings, haemoglobin (the substance in the red blood cells to which the oxygen is fixed) may be transformed to methaemoglobin. Methaemoglobin lacks the ability of binding the oxygen; consequently lack of oxygen occurs in the organism.
Antigen presenting cell: Cells of the immune system, which present antigens on their surface to other immune cells such as the T cells and this way enable proper T cell activation. Antihypertensives: Drugs to treat high blood pressure.
These include the isolation, characterization, and modification of genes and their introduction into living cells or viruses of DNA, ...
A process of inserting new genetic information into existing cells in order to modify a specific organism for the purpose of changing one of its characteristics.
Meristem: regions in a plant where cells are actively dividing or have the potential to divide Monospecific: vegetated or inhabited by one species Mutualism: a relationship between two or more species in which all receive some benefit ...
A mycorrhizal association in which the fungal hyphae are present on root surfaces as individual threads that may penetrate directly into root hairs, other epidermal cells, and occasionally into cortical cells.
Ozone, along with hypochlorite ions, is naturally produced by white blood cells and the roots of marigolds as a means of destroying foreign bodies.
Its central role in living cells makes it an excellent indicator of the presence of living material in water. A measure of ATP therefore provides a sensitive and rapid estimate of Biomass.
leukemia - a form of bone marrow cancer marked by an increase in white blood cells. Go to Top life cycle assessment - methodology developed to assess a product's full environmental costs, from raw material to final disposal.
cloning : In biotechnology, obtaining a group of genetically identical cells from a single cell; making identical copies of a gene. closed-loop recycling : Reclaiming or reusing wastewater for non-potable purposes in an enclosed process.
The amount of a deposited or absorbed compound reaching the cells or target sites where adverse effect occur, or where the chemical interacts with a membrane. Biologicals ...
Toxin: A poisonous substance produced by microorganism cells, particularly bacteria and fungi. The symptoms of a disease caused by bacteria are also due to toxins.
Assimilation Cycle - A natural process by which a water body uses microbes, which convert nonliving substances into protoplasm or cells, to purify itself from pollutants. [Environmental Science and Technology; v26; 1864-1875; 1992.
Viruses: The smallest life forms known, that are not cellular in nature. They live inside the cells of animals, plants and bacteria and often cause disease. They are made up of a chromosome surrounded by a protein shell.
Genetic Engineering: A process of inserting new genetic information into existing cells in order to modify a specific organism for the purpose of changing one of its characteristics.
cancer. A disease characterized by the rapid and uncontrolled growth of aberrant cells into malignant tumors. capillary action. The movement of water through very small spaces due to molecular forces.
Cancer Any one of a group of diseases that occur when cells in the body become abnormal and grow or multiply out of control.
Cancer: A group of diseases characterized by uncontrolled invasive growth of body cells leading to the formation of malignant tumors that tend to grow rapidly and spread (i.e., metastasize).
When carbon monoxide gets into the body, the carbon monoxide combines with chemicals in the blood and prevents the blood from bringing oxygen to cells, tissues and organs.
Respiration is the process where both plants and animals produce energy by burning carbohydrates in their cells using oxygen. Carbon dioxide is produced as a by-product.
The main danger from alpha particles lies in ingesting the atoms which emit them. Body cells next to the atom can then be irradiated over an extended period of time, which may be prolonged if the atoms are taken up in bone, for instance.
Fovea: The point on the retina that corresponds to the central field of vision. The fovea has the highest density of light-receptive cells of any part of the retina. Damage to the fovea can lead to a blind spot in the central field of vision.
Messenger RNA (mRNA): A type of RNA that reflects the exact nucleoside sequence of the genetically active DNA. mRNA carries the "message" of the DNA to the cytoplasm of cells where protein is made in amino acid sequences specified by the mRNA.
The endocrine system has many components, located virtually all over the body, and these components include the hypothalamus, pituitary, pineal, thyroid, and parathyroid glands, the kidney, heart, stomach, and intestines, along with fat cells, ...
Various other strategies include development of new technologies, wind power, nuclear power, renewable energy, biodiesel, electric cars (and hybrids), and fuel cells, Energy conservation, carbon taxes and carbon sequestration schemes.
