WGU Study for OA C190
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.
,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). - 🧠 ANSWER ✔✔
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.
Biomes- - 🧠 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.
biosphere- - 🧠 ANSWER ✔✔All areas on, within, and around the planet
Earth that are capable of supporting life.
Calvin cycle (Calvin-Ben - 🧠 ANSWER ✔✔son cycle or light-independent
reaction)- The set of chemical reactions that take place in chloroplasts
during photosynthesis. The cycle is light-independent because it takes
place after the energy has been captured from sunlight. Also called Calvin-
Benson Cycle, Benson-Calvin Cycle.
Carbohydrates- - 🧠 ANSWER ✔✔The extracellular surface of the cell
membrane is decorated with carbohydrate groups attached to lipids and
