COMPLETE SOLUTIONS GUARANTEED PASS BRAND NEW 2025
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- - CORRECT ANSWER - >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)
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.and fungi are
examples of organisms that reproduce in this manner.
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.
biosphere- - CORRECT ANSWER - >All areas on, within, and
around the planet Earth that are capable of supporting life.
Calvin cycle (Calvin-Ben - CORRECT 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- - CORRECT ANSWER - >The extracellular surface
of the cell membrane is decorated with carbohydrate groups
attached to lipids and proteins. These short carbohydrates play
a role in giving a cell its identity (i.e., distinguishing self from
non-self) and are the distinguishing factor in human blood
types.
carbon cycle- - CORRECT ANSWER - >The biogeochemical cycle
through which carbon flows between the atmosphere, water,
land, and ecosystems.
cell cycle- - CORRECT ANSWER - >A series of phases in the life of
the cell through which it grows and divides.
cell wall- - CORRECT ANSWER - >Protective and reinforcing
structure found in certain cells, situated outside the plasma
membrane. Bacterial cell walls are mainly built of
peptidoglycan, although they may also contain lipidic
molecules. Among eukaryotes, plants and fungi possess cell
walls, made of cellulose and chitin, respectively.
cellular respiration- - CORRECT ANSWER - >Use of oxygen to
release energy from nutrients; also called aerobic respiration.
