BIOLOGY 1120 - QUIZ 5 EXAM WITH
CORRECT ANSWERS 2025
oxygen ( correct answers ) taken in and delivered to tissues
carbon dioxide ( correct answers ) removed from tissues and expelled
cellular respiration( correct answers ) the harvesting of energy
from glucose (consumes O2, gives off CO2) within cells
respiration ( correct answers ) the organism-level exchange of O2 and
CO2 by diffusion ir breathing
what percent of air at all altitudes does oxygen make up? (amount of
O2 available varies with atmospheric pressure) ( correct answers )
21%
oxygen in high altitude migrations ( correct answers ) air is less dense

answers ) Action potentials
Sensory signals are transferred between two neurons via: ( correct
answers ) Neurotransmitters
In human respiration, when the diaphragm pulls down, and the rub cage
expands: ( correct answers )
