Adaptation- - ANSWER - The adjustment or changes in behavior, physiology, and structure of an organism to become more suited to an environment. Aerobic- - ANSWER - A process that requires oxygen. amino acids - - ANSWER - A small organic molecule with the structure of an amino group, a carboxylic acid group, and an "R" group, which are all bonded to a single central carbon atom. The difference between the "R" group is what distinguishes one amino acid from another. Amino acids are the building blocks of proteins. Anaerobic- - ANSWER - A process that occurs without oxygen. Anaphase- - ANSWER - A stage within the mitosis phase of cell division (also known as cell reproduction). Anaphase starts when sister chromatids separate from each other and ends when each set of separated, sister chromatids arrives at the opposite poles of the cell. anaphase I- - ANSWER - The third stage of Meiosis I—the two homologous chromosomes separate and migrate toward opposite poles. anaphase II- - ANSWER - The third stage in Meiosis II—the centromeres separate and the sister chromatids (now individual chromosomes) move toward the opposite poles of the cell. artificial selection- - ANSWER - Deliberate mating between two individuals who were selected based on desired traits. asexual reproduction - - ANSWER - A type of reproduction where genetically identical offspring are created from a single parent. This type of reproduction does not utilize meiosis or gametes. Bacteria and fungi are examples of organisms that reproduce in this manner. - ANSWER - Atom- - ANSWER - The basic unit of matter that cannot be further broken down without losing its unique properties. One atom consists of a dense nucleus surrounded by a cloud of electrons. Autosomal- - ANSWER - Describes a trait associated with alleles located on autosomes (non sex chromosomes). autosomal chromosome- - ANSWER - A chromosome not involved in sex determination. biogeochemical cycle- - ANSWER - The processes that transfer chemical elements between biotic and abiotic components in an ecosystem. There are several main cycles: the water cycle, the carbon cycle, the nitrogen cycle, and the phosphorus cycle. Biome- - ANSWER - A large naturally occurring community of plants and animals occupying a major habitat. Examples include tropical forest and arctic tundra.
