Allen's Rule

Q. Mammals from colder climates generally have shorter ears and limbs to minimise heat loss. This is stated by:

1. Allen’s rule
2. Gloger’s rule
3. Foster’s rule
4. Bergmann’s rule

Q. Which of the following explains Allen’s rule?

1. The presence of CAM pathway
2. The presence of blubber in aquatic mammals
3. Shorter ears and limbs in mammals living in colder regions
4. The huddling together of large groups of penguins to stay warm

Q.

According to Allen’s Rule, the mammals from colder climates have:

1. shorter ears and longer limbs

2. longer ears and shorter limbs

3. shorter ears and shorter limbs

4. longer ears and longer limbs

Q.

How are mammals different from other animals?

Q. Which of the following best describes Allen’s rule?

1. Mammals adapted to colder climates have shorter limbs and ears
2. 
   Mammals adapted to colder climates have longer limbs and ears
3. Mammals adapted to warmer climates have shorter limbs and ears
4. Mammals are well adapted to all climates and hence have the same size of ears and limbs

Q.

According to Allen's rule, mammals in cold regions have ____________ to conserve body heat.

1. Smaller extremities (legs, tails and ears)

2. Longer extremities

3. Smaller body mass

4. Larger body mass

Q.

Small mammals are not found in polar region because
A. they have small surface to volume ratio.
B. they have large surface to volume ratio.
C. they cannot make burrows because of ice cover.
