Bio 117 Final WVU Barry
acquired immunodeficiency syndrome (AIDS) - correct answer--Caused by HIV
-will succumb to illness not seen in people with healthy immune systems
acromagly - correct answer-over production of growth hormones after puberty
- increased size, swollen tissues/hands, deeper voice, brow and jaw protursion
action potential - correct answer-a wave of changing charge that moves down
active transport in plant - correct answer-input and output of carbohydrates into/out if phloem
adaptive immune recognition - correct answer-based on interactions between specific
immune system cells and a specific antigen
adaptive immunitity - correct answer-cells that must first be selectively activated to tailor their
response to a specific pathogen
allergic reaction - correct answer--an abnormal over-reactive response to an antigen
-due to IgE antibodies produced in response to non-pathogen molecules
ex. dander, nuts, pollen
amyloplasts - correct answer-huge granules of starch that are pulled down by gravity
antibodies - correct answer-secreted proteins that bind to a specific antigen
antigen - correct answer-any molecule on the surface of an invader that helps to generate
antibody for that invader
antigen presentation - correct answer--T-cells require other cells to process antigens and
present TCRs
-dedritic cells attack the antigen and report back to lymph nodes
-antigen presentation prepares the T cell to recognize the antigen
apical dominance - correct answer--reduces shading of lower branches by lower branches
-primary growth restricted to main stem
Attenuated, or "live" viruses - correct answer-consist of complete virus particles that have
lost the ability to grow rapidly in their normal host cells
ex. smallpox, polio, meases
autocrine chemical signals - correct answer-acts on same cell that secretes them
, autoimmunity - correct answer-an immune system response directed against molecules or
cells that normally exist
autonomic nervous system - correct answer-involuntary actions
auxins - correct answer-produced in the apical meristems and cause cell elongation and the
growth of new roots
-phototrophic and gravitrophic responses
B cell receptors (BCR) - correct answer-the protein on the surface of the B cells that bind to
antigens
-same structure as the antibodies produced by B cells
B cells - correct answer-produce antibodies
mature in bond marrow
capillary action (three) - correct answer-1. cohesion
- water molecules are "sticky" with one another
2. adhesion
- water molecules can "stick" to the inner surface of their container
3. surface tension
- water molecules of the surface are pulled down by interactions with those molecules below
CAR T cell therapy - correct answer-T cells are removed from a patient and modified so that
they express CAR receptors specific to the patient's particular cancer. The T cells, which can
then recognize and kill the cancer cells, are reintroduced into the patient.
CD4+ T cells - correct answer--Helper T cells
-help activate B cells and cytotoxic T cells
CD8+ T cells - correct answer--Cytotoxic T cells
-kill cells that are infected with an intracellular pathogen
cell body of neuron - correct answer-Soma
enlarged region containing the nuclues
cells manipulate ions - correct answer-1. actively pumping
2. letting them pass through certain facilitated diffusion channels
central nervous system - correct answer-brain and spinal cord
clonal selection theory - correct answer-1. Antigens are recognized by receptors on B cells
and T cells
2. Lymphocytes require receptor-epitope binding to become activated
