Adaptation- - correct answer The adjustment or changes in behavior, physiology, and structure of an organism to become more suited to an environment. Aerobic- - correct answer A process that requires oxygen. Allele -An alternative form of a gene. An example would be genes that encode eye color—some encode blue eyes (one allele), while others encode brown, green, or hazel eye colors (other alleles). - correct answer amino acids - - correct 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- - correct answer A process that occurs without oxygen. Anaphase- - correct 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- - correct answer The third stage of Meiosis I—the two homologous chromosomes separate and migrate toward opposite poles. anaphase II- - correct 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- - correct answer Deliberate mating between two individuals who were selected based on desired traits. asexual reproduction - - correct 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. - correct answer Atom- - correct 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- - correct answer Describes a trait associated with alleles located on autosomes (non sex chromosomes). autosomal chromosome- - correct answer A chromosome not involved in sex determination. biogeochemical cycle- - correct 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- - correct answer A large naturally occurring community of plants and animals occupying a major habitat. Examples include tropical forest and arctic tundra. Biomes- - correct answer A pattern of distribution of ecosystems across the globe, where similar environmental conditions lead to similar animal and plant adaptations. Examples of biomes include tropical rainforests, deserts, and tundra.
