Why do frogs need to keep their skin moist?
To protect themselves from predators.
To enable diffusion of oxygen through their skin.
To help them jump higher.
To regulate their body temperature.
How does gas exchange occur through a frog’s skin?
Through breathing into their lungs.
By absorbing oxygen through mucus.
By diffusing oxygen into blood vessels near the skin’s surface.
By actively pumping oxygen into cells.
What role does mucus play in a frog’s respiration?
Helps in digesting food.
Protects the skin from drying out, aiding in breathing.
Absorbs carbon dioxide.
Prevents oxygen from entering the skin.
How does a frog breathe through its mouth?
By using its lungs to circulate oxygen from the mouth.
By diffusing oxygen directly into the bloodstream through the mouth lining.
By trapping air and swallowing it.

How do frogs exhale carbon dioxide when breathing through their mouth?
Through their skin.
By expelling it through their lungs.
By diffusing it out of the mouth into the environment.
By storing it in mucus glands.
