biotic
living
biosphere
Consists of all life on Earth and all parts of the Earth in which life exists, including
land, water, and the atmosphere.
DNA
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
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
two strands of nucleotides wound about each other; structure of DNA
cell specialization
Cells throughout an organism can develop in different ways to perform different
tasks.
cell differentation
, 2
Process by which cells become different types of cells
carbon cycle
Cyclic movement of carbon in different chemical forms from the environment to
organisms and then back to the environment.
cell differentiation
the process by which a cell becomes specialized for a specific structure or function
chemical bond
the attractive force that holds atoms or ions together where the energy in a
compound is stored
chromosome pair
identical copies of a single chromosome
copy of mom chromosome 1 next to mom chromosome 1
consumer
an organism that obtains energy by feeding on other organisms
deletion
the loss of a part of DNA from a chromosome
detritivore
An organism (like the earthworm) that feeds on decaying matter after it has been
broken down by decomposers.
ecosystem stability
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
A species whose numbers are so small that the species is at risk of extinction
