Biology Final Exam Study Questions Correctly
Solved to Score A+
abiotic - Answer non-living
autotroph - Answer An organism that makes its own food.
asexual reproduction - Answer a reproductive process that involves only one parent and produces
offspring that are identical to the parent
biotic - Answer living
biosphere - Answer Consists of all life on Earth and all parts of the Earth in which life exists, including
land, water, and the atmosphere.
cell specialization - Answer Cells throughout an organism can develop in different ways to perform
different tasks.
cell differentation - Answer Process by which cells become different types of cells
carbon cycle - Answer Cyclic movement of carbon in different chemical forms from the environment to
organisms and then back to the environment.
cell differentiation - Answer the process by which a cell becomes specialized for a specific structure or
function
chemical bond - Answer the attractive force that holds atoms or ions together where the energy in a
compound is stored
chromosome pair - Answer identical copies of a single chromosome
copy of mom chromosome 1 next to mom chromosome 1
, consumer - Answer an organism that obtains energy by feeding on other organisms
deletion - Answer the loss of a part of DNA from a chromosome
detritivore - Answer An organism (like the earthworm) that feeds on decaying matter after it has been
broken down by decomposers.
DNA - Answer 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 - Answer 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 - Answer two strands of nucleotides wound about each other; structure of DNA
ecosystem stability - Answer 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 - Answer A species whose numbers are so small that the species is at risk of
extinction
exponential growth - Answer growth pattern in which the individuals in a population reproduce at a
constant rate
food web - Answer a community of organisms where there are several interrelated food chains
gene - Answer sequence of DNA that codes for a protein and thus determines a trait
genetic diversity - Answer the amount of variation in the genetic material within all members of a
popualtion
