Answer: The correct answer for the blank is- A) Have hairs.

As per the University of Michigan, there are primarily three characteristics/ features that are unique to mammals. These are as follows-

1) Presence of hairs on body.

2) Presence of mammary glands ( primarily used of feeding the neonates).

3) Presence of three bones in the middle ear ( that is Malleus, incus, and stapes).

The most significant function of hairs in mammals is that they provide insulation against cold by conserving heat of body. In certain nocturnal animals ( which are active during night time), they serve as sensory organs.

Thus, option A) is the right answer.

What kind of currents bring warm air to land?
Zinaida [17]

Answer: A warm current is just the reverse. A warm current is moving away from the Equator toward the poles. The water in a warm current is warmer than the surrounding water.

Explanation: The surface water temperature varies considerably between the Equator and the poles. As the ocean water is distributed across the Earth's surface by drifts and currents (see the infrared satellite photo of the warm Gulf Stream moving north along the east coast of Florida), warm water from the lower latitudes is moved into the higher latitudes and cold water is moved Equatorward. If you will remember, we noted in the section on Latitude that this redistribution of heat by ocean water is one of the major ways excess energy is moved poleward (and cold water is moved Equatorward).

I hope this helps, good luck
