Active Immunity Correct Answer Microbe introduced into the
body to stimulate a response to a certain disease
Adaptive Radiation Correct Answer Divergence of a group
into species adapted to many ecological niches
Adrenal Gland Correct Answer Regulate hormones of Fight
or flight
Alimentary system Correct Answer System involved in the
acquisition of nutrients from food
Alimentary System Correct Answer System involved in the
acquisition of nutrients from food
Ametabolous Correct Answer Growth without major change
in form
Amniotes Correct Answer Tetrapods that have amniotic egg
Amylase Correct Answer Enzyme that breaks down
carbohydrates into maltose
Anhydrobiosis Correct Answer Adaptation to allow the body
to lose all water and enter a dormant state
,Animals Correct Answer Multicellular eukaryotes
Heterotrophs: Ingest their food
Lack Cell Walls
Body held together by structural proteins
Anterior Pituitary Correct Answer Makes and releases
hormones under regulation of the hypothalamus
Antibody Correct Answer Free molecules with antigen
binding sites
Antigens Correct Answer Foreign molecule to which
lymphocytes have an immune response
Antlers Correct Answer Solid bone surrounded during its
growth phase by a highly vascular, soft skin called velvet
Anuran Circulation (Frogs) Correct Answer Efficient, Closed
circulatory system. Three chambered heart and separate lung,
and systemic circuits
