Question

1.

Which of the following statements is FALSE?

Homeotherms can sustain a high level of physical activity for long periods.

Homeotherms require a very low amount of glucose for daily activities.

Homeotherms can generate energy rapidly when the situation demands.

Homeothermy allows organisms to function at a higher level in cold environments.

Homeotherms have relatively higher metabolic rates than similar-sized poikilotherms.

2.

Larger terrestrial animals (mammals, birds, and reptiles) acquire oxygen through __________.

their skin

air sacs

the membranes in their nasal passages

their lungs

their gills

3.

Some amphibians can take in oxygen through their skin.

True

False

4.

Metabolic water is __________.

water lost through urine formation

water reabsorbed through the kidneys or cloaca

water created through photosynthesis

water created as a product of cellular respiration

water obtained through the ingestion of succulent plants

5.

Daily torpor is more likely to be used by large mammals than small mammals to conserve energy when inactive.

True

False

6.

Organisms must have special adaptations to survive extreme cold. Which of the following is NOT one of those adaptations?

Some aquatic insects survive winter by actually freezing and then thawing out when the temperature rises to normal.

Many species of camels can store body heat during the day and release it at night.

The porpoise has countercurrent heat exchange.

Many frog species can survive winter through super-cooling, accumulating glycerol in their blood.

Intertidal organisms in cold regions may freeze and thaw.

Answer 1

Ans1. Homeotherms require a very low amount of glucose for daily activities.

to maintain their body temperature and the ability to function in cold environment requires a lot of energy. therefore a large amount of glucose is required to survive in cold condition.

Ans2. their lungs

All terrestrial vertebrates breathe exclusively with lungs.

Ans3. true

some adult frogs breathe through their lungs and exchange gases through their skin . they respire through the many folds in their thin skin.

Ans4. water created as a product of cellular respiration

it is also called water of oxidation. Water is produced by our bodies as a byproduct during the process of cellular respiration.

Ans5. false

Torpor is a state which enables animals to survive periods of reduced food availability by decreasing their physiological activity. daily torpor is usually used by birds and some small mammals like rodent species-mice. Bats etc.
