Term | Definition |
Amino Acid | Amino acids are biologically important organic compounds composed of amine and carboxylic acid functional groups, along with a side-chain specific to each amino acid |
Asteroid | a small rocky body orbiting the sun. Large numbers of these, ranging in size from nearly 600 miles (1,000 km) across (Ceres) to dust particles |
Mass | a coherent, typically large body of matter with no definite shape. |
Beta Particles | a fast-moving electron emitted by radioactive decay of substances. (The emission of beta particles was originally regarded as a ray.). |
Biomass | the total mass of organisms in a given area or volume |
Biosphere | the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms. |
Bog | wet muddy ground too soft to support a heavy body. |
Buoyancy | the ability or tendency to float in water or air or some other fluid. |
Calcite | a white or colorless mineral consisting of calcium carbonate. It is a major constituent of sedimentary rocks such as limestone, marble, and chalk, can occur in crystalline form |
Capacity | the maximum amount that something can contain |
Capillary | any of the fine branching blood vessels that form a network between the arterioles and venules. |
Carbon Dioxide | a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis. |
Carbonate | a salt of the anion CO32–, typically formed by reaction of carbon dioxide with bases. |
Chromatid | each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA. |
Chromosome | a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. |
Climatic | relating to climate. |
Comet | a celestial object consisting of a nucleus of ice and dust and, when near the sun, a “tail” of gas and dust particles pointing away from the sun. |
Condensation | water that collects as droplets on a cold surface when humid air is in contact with it. |
Cytoplasm | the material or protoplasm within a living cell, excluding the nucleus. |
Denature | destroy the characteristic properties of (a protein or other biological macromolecule) by heat, acidity, or other effects that disrupt its molecular conformation. |
Density | the degree of compactness of a substance |
Diffuse | spread or cause to spread over a wide area or among a large number of people. |
Ecology | the branch of biology that deals with the relations of organisms to one another and to their physical surroundings. |
Ecosystem | a biological community of interacting organisms and their physical environment. |
Erosion | the process of eroding or being eroded by wind, water, or other natural agents. |
Extinct | (of a species, family, or other larger group) having no living members. |
Flask | a narrow-necked glass container, typically conical or spherical, used in a laboratory to hold reagents or samples. |
Glacier | a slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles. |
Landmass | a continent or other large body of land. |
Lava | hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this. |
