Answer:
c. pituitary gland
Explanation:
The hypo(below) thalamus is an almond size structure located superiorly to the brainstem. it is located below the thalamus. Hence the name hypothalamus.
It is primary function is is to control the body homeostatic functions of sleeping and waking up, sex, thirst and hunger etc.
It performs these roles by serving as the primary link of the nervous system with the endocrine system. Pituitary gland is an example of endocrine gland that secrets many hormones. (they are called endocrine because the hormones are secreted directly into the blood streams.
<u>Its activities are controlled by the nervous stimulation from hypothalamus. Therefore the instructions to secretes certain hormones to the post and anterior part of the pituitary gland depends on the hypothalamus.</u>
Growth hormones, oestrogen, and thyroid are examples of hormones of the pituitary glands.
45 guanine, 55 adenines
Every cytosine needs a guanine to be a pair, so that is 45 pairs right there.
100-45 = 55
There should be 55 adenine and thymine pairs to fill in the remaining bases
Continual questioning of observations.
The amount of CO2 absorbed by plants through photosynthesis is enormous plants have the ability to absorb and in turn sequester enormous amounts of carbon over a very long time much of the excess atmospheric CO2 is from the result of burning phonology fuels
Answer: 2 - The nucleus of an atom is split apart
Explanation: Any reaction involving the nucleus of an atom is called a nuclear reaction. It is different from ordinary chemical reactions that involve electrons because it involves the release of large amount of energy. Nuclear reactions can be classified as nuclear fission and nuclear fusion.
A nuclear reaction in which a nucleus of an atom is split into two smaller atoms with a release of large amount of energy is called nuclear fission. A nuclear reaction that involves the combination of lighter nuclei of elements to form heavier atoms that are more stable with the release of a large quantity of energy is called nuclear fusion.
