Flashcards do conjunto (28)
- 1AdaptationAdaptation, in biology, the process by which a living thing becomes better suited to its environment.
- 2AgeThe length of time an organism has lived or normally lives, or the length of time an object or material has existed.
- 3AlbuminAlbumin, a simple protein found in most animals and in some plants. Albumins dissolve in water and dilute salt solutions and coagulate (curdle or clot) in the presence of heat.
- 4Amino AcidAmino Acids, chemical compounds produced by living organisms. Many amino acids are the structural units of proteins.
- 5BiologyBiology, the science that deals with living things. The earth is home to a diverse range of living organisms.
- 6EvolutionEvolution, as defined in biology, the continual process by which one form of life changes, or evolves, into another form.
- 7MicrobiologyMicrobiology, the branch of biology concerned with microorganisms including viruses, bacteria, protozoans, and certain algae and fungi.
- 8MicroorganismMicroorganism, or Microbe, an organism so small that it cannot be seen without the aid of a microscope.
- 9MutationMutation, in a general sense, any change in the genetic makeup of an organism; such a change usually causes the organism to have a trait not possessed by any of its ancestors.
- 10OsmosisOsmosis, the spontaneous flow of a liquid or gaseous substance through a semipermeable membrane.
- 11PhotosynthesisPhotosynthesis, the conversion of light energy into chemical energy in cells that contain chlorophyll, a green pigment.
- 12ProteinProtein, a large, complex organic molecule. Proteins are found in all living cells, making up about one-half of the dry weight of most organisms.
- 13SporeSpore, a tiny reproductive body that is typically unicellular. Spores are usually produced asexually.
- 14AssimilationAssimilation, in biology, the process by which plants and animals utilize foods in the building of living tissue.
- 15Balance of NatureBalance of Nature, or Ecological Balance, the balanced relationship of the plants, animals, and other living organisms that make up a natural community.
- 16BioethicsBioethics, the study of the ethical questions arising from biological (especially medical) research and technology.
- 17BiofeedbackBiofeedback, a process in which a person can learn to influence certain bodily functions that scientists once believed were beyond conscious control.
- 18Biological clockBiological Clock, a popular term for an internal regulator responsible for various cyclical responses in living things.
- 19BioluminescenceBioluminescence, the production of light by living organisms as the result of chemical changes.
- 20CarbohydratesCarbohydrates, a class of chemical compounds that are composed of carbon, hydrogen, and oxygen.
- 21Carbon CycleCarbon Cycle, the series of natural processes by which carbon in the air is made available to living things, is used by them, and is then returned to the air.
- 22CyberneticsCybernetics, the study and comparison of the way in which animals and machines control their movements and internal functions.
- 23FamilyFamily, in biology, a group of living things believed to have a common ancestor. A family consists of one or more genera (singular: genus) made up of one or more species, or distinctive kinds, of living things.
- 24FermentationFermentation, a type of anaerobic respiration, an energy-releasing process that takes place in the absence of free (chemically uncombined) oxygen.
- 25KingdomKingdom, in natural science, one of several groups into which objects are classified.
- 26ParasiteParasite, an organism that lives in or on another organism, called the host, from which it obtains its food.
- 27SymbiosisSymbiosis, a close association between two different organisms. Symbiosis is a Greek word that means “living together.” In one type of symbiosis, known as mutualism, both partners benefit from the association.
- 28VarietyVariety, in biology, a group of plants or animals within a species. Varieties of animals are usually called breeds.
