Animal physiology - ..(ANSWER)...The study of animal function.
Conformity - ..(ANSWER)...When an animal's internal environment matches the
external environment as conditions change.
Regulation - ..(ANSWER)...When an animal maintains a constant internal
environment regardless of changes in the external environment.
Natural selection - ..(ANSWER)...A key process for the evolutionary origin of
physiological traits, where traits providing an adaptive advantage are more likely
to be passed down.
Phospholipid molecule - ..(ANSWER)...An amphipathic molecule with a
hydrophobic nonpolar fatty acid tail and a hydrophilic polar head, forming the
basis of cell membranes.
Fluidity of a phospholipid membrane - ..(ANSWER)...Influenced by the degree of
saturation of the fatty acid tails and temperature.
Integral membrane proteins - ..(ANSWER)...Proteins embedded within or
spanning the entire phospholipid bilayer of a cell membrane.
, 2
Peripheral membrane proteins - ..(ANSWER)...Proteins located on one side of the
membrane, not embedded within the bilayer.
Enzymes - ..(ANSWER)...Protein catalysts that speed up chemical reactions in the
body without being consumed.
Transcriptomics - ..(ANSWER)...The study of which genes within a genome are
transcribed into mRNA, providing information on gene expression.
Polyphenic development - ..(ANSWER)...A category of phenotypic plasticity where
genetically identical individuals can develop into distinct body forms in response
to environmental cues.
Example of polyphenic development - ..(ANSWER)...The migratory locust, which
can develop into solitary or gregarious forms depending on population density.
Primary active transport - ..(ANSWER)...Uses metabolic energy directly, typically
from ATP hydrolysis, to move solutes against their electrochemical gradient.
Secondary active transport - ..(ANSWER)...Draws energy from an electrochemical
gradient established by primary active transport to move another solute.
Levels of organization in animals - ..(ANSWER)...Various structural levels in
animals influenced by environmental factors.
