Q

What is the role of the skin in frog respiration?

Q

What is the function of the vocal sacs in male frogs?

A

Vocal sacs are used for calling and attracting mates, not for respiration.

17
Q

Multiple Choice: Which stage of a frog’s life cycle is characterized primarily by cutaneous respiration? A) Egg B) Tadpole C) Adult D) All stages

A

C) Adult

18
Q

What is the effect of temperature on frog respiration?

A

Higher temperatures can increase the metabolic rate and respiratory rate in frogs.

19
Q

True or False: Frogs have a single respiratory system that functions similarly to that of mammals.

A

False. Frogs have both cutaneous and pulmonary respiration.

20
Q

What adaptations do frogs have for surviving in aquatic environments?

A

Frogs have permeable skin and can use cutaneous respiration while submerged.

21
Q

Fill in the blank: The exchange of gases in frog lungs occurs in tiny air sacs called __________.

A

alveoli

22
Q

How does the respiratory system of frogs differ from that of reptiles?

A

Frogs can respire through their skin, while reptiles rely mainly on lungs.

23
Q

What role does the diaphragm play in frog respiration?

A

Frogs do not have a diaphragm; they use buccal pumping instead.

24
Q

Multiple Choice: During which activity do frogs primarily use their lungs for respiration? A) Swimming B) Jumping C) Resting D) All of the above

A

B) Jumping

25
Q

True or False: Frogs are entirely dependent on lungs for respiration after metamorphosis.

A

False. They can still use cutaneous respiration.
