Conformation

Q. The organism in which body temperature changes with the ambient temperature and in aquatic animals, the osmotic concentration of the body fluid changes with that of the ambient water osmotic concentration. These animals and plants are simply

1. Conformers
2. Migratory
3. Hibernating
4. Regulators

Q. Aquatic organisms that maintain an internal environment that is isosmotic to their external environment are known as

1. Osmoconformers
2. Osmoregulators
3. Homeotherms
4. Poikilotherms

Q. Consider the following statements.

Assertion: Animals like shrews and hummingbirds are conformers.
Reason: These animals have large volume compared to their surface area leading to rapid heat loss from the body.

1. Assertion is true but the reason is false
2. Both assertion and reason are false
3. Both assertion and reason are true and the reason is the correct explanation for the assertion
4. Both assertion and reason are true but the reason is not the correct explanation for the assertion
