Biology Final Exam Review with
complete questions and correct
answers 2025
cell differentiation - CORRECT ANSWERS--the process by which a cell becomes
specialized for a specific structure or function
chemical bond - CORRECT ANSWERS--the attractive force that holds atoms or ions
together where the energy in a compound is stored
chromosome pair - CORRECT ANSWERS--identical copies of a single chromosome
copy of mom chromosome 1 next to mom chromosome 1
consumer - CORRECT ANSWERS--an organism that obtains energy by feeding on
other organisms
deletion - CORRECT ANSWERS--the loss of a part of DNA from a chromosome
detritivore - CORRECT ANSWERS--An organism (like the earthworm) that feeds on
decaying matter after it has been broken down by decomposers.
, DNA - CORRECT ANSWERS--deoxyribonucleic acid; the genetic material that carries
information about an organism that is passed from parent to offspring AND is used by
an individual as the recipe for making proteins
DNA sequence - CORRECT ANSWERS--The sequence, or order, in which the
nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T) are arranged
in a gene or a DNA fragment, or in an organism's genome.
double helix - CORRECT ANSWERS--two strands of nucleotides wound about each
other; structure of DNA
ecosystem stability - CORRECT ANSWERS--the total number of species is fairly
consistant from year to year---the same species were present each year--- the
population size of each species was approximately the same from year to year
endangered species - CORRECT ANSWERS--A species whose numbers are so small
that the species is at risk of extinction
exponential growth - CORRECT ANSWERS--growth pattern in which the individuals in
a population reproduce at a constant rate
food web - CORRECT ANSWERS--a community of organisms where there are several
interrelated food chains
gene - CORRECT ANSWERS--sequence of DNA that codes for a protein and thus
determines a trait
genetic diversity - CORRECT ANSWERS--the amount of variation in the genetic
material within all members of a popualtion
genetic variation - CORRECT ANSWERS--The variety of different types of genes in a
species or population.
genotype - CORRECT ANSWERS--an organism's genetic makeup, or allele
combinations
greenhouse effect - CORRECT ANSWERS--natural situation in which heat is retained in
Earth's atmosphere by carbon dioxide, methane, water vapor, and other gases
heterozygous - CORRECT ANSWERS--having two different alleles for a trait
heterotroph - CORRECT ANSWERS--An organism that cannot make its own food and
thus eats other organisms
homeostasis - CORRECT ANSWERS--Process by which organisms maintain a
relatively stable internal environment.
