C190 Intro to Biology (WGU) questions with
verified answers
Abiotic Ans✓✓✓-An adjective that describes nonliving materials in the
environment, such as sunlight, rain, gases in the air, rocks, and chemicals in the
soil.
acetyl coA Ans✓✓✓-A two-carbon molecule that is an intermediate product
between glycolysis and the Krebs cycle in cellular respiration.
Active transport Ans✓✓✓-The movement of a substance across a biological
membrane against its concentration gradient, aided by specific transport proteins
and requiring input of energy (often as ATP).
Adhesion Ans✓✓✓-The attraction of water molecules to molecules other than
water.
aerobic Ans✓✓✓-A process that requires oxygen.
Allele Ans✓✓✓-An alternative form of a gene
Amino Acids Ans✓✓✓-Molecules containing an amine group, a carboxylic acid
group, and a specific side-chain.
anaerobic Ans✓✓✓-A process that occurs without oxygen.
,Anaphase 1 Ans✓✓✓-The third stage of Meiosis I—the two homologous
chromosomes separate and migrate toward opposite poles.
Anaphase 2 Ans✓✓✓-The third stage in Meiosis II—the centromeres separate
and the sister chromatids (now individual chromosomes) move toward the
opposite poles of the cell.
Anaphase Ans✓✓✓-A stage within the mitosis phase of cell division (also known
as cell reproduction). 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.
Asexual reproduction Ans✓✓✓-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.
Atom Ans✓✓✓-The basic unit of matter that cannot be further broken down
without losing its unique properties. Consists of a dense nucleus surrounded by a
cloud of electrons.
ATP Ans✓✓✓-small organic molecule with three phosphate groups attached that
acts as the direct source of energy for almost all cellular activities. It is a relatively
unstable molecule; therefore, it is never used for long-term storage of energy in
the cell.
Autosomal chromosome Ans✓✓✓-A chromosome not involved in sex
determination.
, Biology Ans✓✓✓-The scientific study of life. Including anatomy, biochemistry,
ecology, evolution, genetics, immunology, and physiology.
Biome Ans✓✓✓-A large naturally occurring community of plants and animals
occupying a major habitat. Examples include tropical forest and arctic tundra.
Biosphere Ans✓✓✓-All areas on, within, and around the planet Earth that are
capable of supporting life.
Biotic Ans✓✓✓-An adjective that describes living organisms or their remains.
Common characteristics are that they use energy and raw materials to grow,
sense, and respond to changing environments; they reproduce; and they consist
of one or more cells.
Calvin cycle Ans✓✓✓-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.
Carbohydrates Ans✓✓✓-The extracellular surface of the cell membrane is
decorated with _______ groups attached to lipids and proteins. Play a role in
giving a cell its identity
Cell Ans✓✓✓-The smallest fundamental unit of structure and function in life.
Fluid-filled spaces bound by a membrane. When first formed, include DNA and
other macromolecules and are organized to grow, reproduce, and respond to
changes in the external environment.
Cell cycle Ans✓✓✓-A series of phases in the life of the cell through which it
grows and divides.
