prisoha [69]2 years ago

<span>The component that nitrogen-fixing bacteria provide and that plants can absorb is soluble nitrates. Since plants cannot directly use nitrogen gas, it must be converted into its soluble form. Plants cannot do this either, but nitrogen-fixing bacteria can. These bacteria convert nitrogen gas into soluble nitrates, such as ammonium, which plants can absorb.</span>

Which statement regarding the hypothalamus is FALSE?
Margarita [4]

Answer:

All the options are correct regarding hypothalamus.

Explanation:

The hypothalamus is the part of the forebrain. The diencephalon is divisible into 2 parts - thalamus and hypothalamus. It regulates various functions of the body.

This is the thermoregulatory center of the body. It gives the signal to sweat during a hot environment and shiver in winter. This maintains the water balance in the body by stimulating the secretion of ADH hormone in the kidney.

Hypothalamus also has regulated anterior pituitary hormone secretion. Thus it controls the endocrine secretion of pituitary glands.

This plays an important role in hunger and thirst. The feeding habits like the licking of lips, swallowing, and salivating by seeing delicious foods is due to hypothalamic activities.

The behavioral activities of individuals influenced by the hypothalamus.  It is worked along with the limbic system of the brain. The behavioral activities include fear, punishment and sexual desire.

Karolina [17]

Answer:

allopatric speciation.

Explanation:

  • When the population belonging to the same biological species becomes separated from each other due to some geographical factor such that no gene flow can occur between the two separated populations then the speciation that occurs on account of this is known as allopatric speciation.
  • The geographical isolation that separates the two groups can be the origin of a mountain,  the formation of islands, volcanic eruption, etc. which prevents the two groups fro mating with each other and ultimately causes their lineage to speciate.
  • Although the two separate populations are unable to mate due to geographical factors, if the two populations are allowed to mate again, given that they have not been separated very long ago, they can give rise to hybrids.
  • Thus, in the given question it is given that polar bears and grizzly bears have been mated and hybrids have been produced and this points out to the fact that polar bears are result of allopatric speciation.
