B. Animals must switch between ectotherm and endotherm methods.

The hypothalamus in the brain, is responsible for monitoring the body temperature. The hypothalamus causes the body to react differently when the body is too hot or if the temperature gets too cold. The normal body temperature is 37'. The hypothalamus triggers the receptors such as sweat glands and body hair muscles in the body.The sweat glands open up when the body is too hot and secrets sweat until the temperature is regulated again. Similarly in cold conditions the body hair muscles pull the hair upright because standing hair absorbs more heat until the falling body temperature returns to normal.

Identify the process in the water cycle that changed water vapor into liquid water droplets that formed the thunderstorm cloud?

kicyunya [14]

Water heats up, changes to water vapor and evaporates, rises into the sky. It cools, condenses, turns back into liquid water forming clouds. Then it falls back to earth as precipitation and runs down hills or mountains during runoff and returns to lakes and oceans.

In mice, a male and female are mated, both with long ears. All female have long ears but half the males bave short ears and half

rjkz [21]

If you have both parents with long ears and some of the offsprings have short ears, you can say both parents are heterozygous for this. Both have a dominant (long ear), and a recessive allele (short ear).

To prove this, you can draw a Punnett square, and you'll see the probabilities of the offsprings.
