The adjustment or changes in behavior, physiology,
Adaptation- and structure of an organism to become more
suited to an environment.
Aerobic- 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).
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
amino acids -
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- A process that occurs without oxygen.

A stage within the mitosis phase of cell division (also
known as cell reproduction). Anaphase starts when
Anaphase- sister chromatids separate from each other and
ends when each set of separated, sister chromatids
arrives at the opposite poles of the cell.
The third stage of Meiosis I—the two homologous
anaphase I- chromosomes separate and migrate toward
opposite poles.
The third stage in Meiosis II—the centromeres
separate and the sister chromatids (now individual
anaphase II-
chromosomes) move toward the opposite poles of
the cell.
Deliberate mating between two individuals who
artificial selection-
were selected based on desired traits.
A type of reproduction where genetically identical
offspring are created from a single parent. This type
asexual reproduction -
of reproduction does not utilize meiosis or gametes.
Bacteria
and fungi are examples of
organisms that reproduce
in this manner.
The basic unit of matter that cannot be further
broken down without losing its unique properties.
Atom-
One atom consists of a dense nucleus surrounded
by a cloud of electrons.
Describes a trait associated with alleles located on
Autosomal-
autosomes (non sex chromosomes).
autosomal chromosome- A chromosome not involved in sex determination.
The processes that transfer chemical elements
between biotic and abiotic components in an
biogeochemical cycle- ecosystem. There are several main cycles: the water
cycle, the carbon cycle, the nitrogen cycle, and the
phosphorus cycle.

A specific section of a chromosome where spindle

connection point of sister chromatids.
A plant pigment used to absorb light energy for
photosynthesis. Chlorophyll gives plants their green
Chlorophyll-
color because it absorbs red and blue light
particularly well, while reflecting green.
An organelle found in plants and photosynthetic
protists (single-celled eukaryotic organisms) that
contain pigments such as chlorophyl. Its primary
function is to capture solar energy and convert it
into chemical energy through the process of
Chloroplast-
photosynthesis. Chloroplast absorbs sunlight energy
and uses the energy to power the synthesis of
organic food molecules (sugars). A chloroplast
contains its own DNA as a single circular
chromosome.
One of two identical copies of a chromosome
duplicated during the S phase of the cell cycle. A
centromere connects two sister chromatids
Sister Chromatid - together. When joined together, sister chromatids
compose one chromosome. Chromatids are
separated from each other during mitosis or meiosis
II.
The 2nd stage of aerobic cellular respiration that
occurs when acetyl CoA combines with a four-
Citric acid cycle- carbon molecule and goes through a cycle of
reactions, ultimately producing ATP, NADH, FADH2,
and CO2.
It is the full range of climatic disruptions that have
occurred as a probable result of human alteration of
climate change- the atmosphere. In other words, it is recent climate
warming—and weirdness—that is probably caused
by human activities and technology use.
