Terms in this set (388)
acid a substance with a pH less than 7
activation energy the minimum energy needed to intiate a chemical
reaction
active immunity protection against a specific pathogen resulting from
the production of antibodies in response to the
presence of specific antigens
,active transport movement across a cell membrane that travels against
the concentration gradient and thus requires energy
adaptive defense a specific response by the immune system to a given
pathogen
adaptive immune system a kind of passive or active immunity in which antibodies
to a particular antigen are present in the body
adhesiveness a measure of how well dissimilar particles or surfaces
cling to one another
adrenal a gland above the kidney that produces hormones to
regulate heart rate, blood pressure, and other functions
aldosterone a hormone secreted by the adrenal gland that increases
reabsorption of sodium ions
allele a specific copy of a gene
allergies an immune response to a foreign agent that is not a
pathogen
alveoli tiny air sacs in the lungs where exchange of oxygen and
carbon dioxide takes place
amino acids the monomers that make up proteins
anaphase the stage in mitosis in which the chromosomes are
pulled apart to the poles and cell division begins
, anaphase I the stage in meiosis I in which homologous
chromosomes move to opposite ends of the cell
anaphase II the stage in meiosis II in which sister chromatids
separate and move to opposite ends of the cell
anatomical position standard positioning of the body as standing; feet
together, arms to the side; with head, eyes, and palms
of hands forward
angiotensin II a secretion that acts to restore blood volume and blood
pressure by constricting blood vessels, stimulating
thirst, and stimulating production of aldosterone and
antidiuretic hormone
anion a negatively charged ion
antagonist the relaxed muscle in the pair of muscles taht is involved
in a given movement
antibody-mediated immunity a defense that employs B cells to create antibodies that
tag pathogens for later destruction. Also known as
humoral immunity
antibody a blood protein that counteracts a specific antigen
antidiuretic hormone a secretion from the pituitary gland that increases the
amount of water able to be reabsorbed from a
collecting duct
