Answer:
Growth-hormone-inhibiting hormone or somastostatin.
Explanation:
Basically the GH is secreted by the anterior pituitary glands under the regulations of certain secretory nuclei in the hypothalamus.The cells of these nuclei secrets two hormones,
1. growth hormones releasing hormone which stimulate growth hormones releasing-receptors receptors for the pituitary glands to secrets growth hormones,
and
2. the Growth-hormones-inhibiting hormones. This hormone is secreted, and carried in the blood stream by <u>hypothalamo-hypophsial-portal circulation</u> in response to elevated levels of GH. They inhibit the secretion of Growth hormones in the pituitary glands;by inhibiting the activities of growth-hormones -releasing hormone, preventing them from binding with <u>growth-hormone-releasing hormones receptors</u> in the anterior pituitary gland,therefore inhibiting GH secretions .
Answer: number one is A, vaculoe
number two is F, nucleous
During interphase, the cell grows, accumulating nutrients needed for mitosis, preparing it for a big cell division and duplicating its DNA. During the mitotic phase, the chromosomes separate. During the final stage, cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells.
<span>The structure of a paramecium that holds a "reserve copy" of all the cell's genes is the micro nucleus.
</span>The micro nucelus is one of the <span>two kinds of </span>nuclei the paramecium has. The other is the<span> large ellipsoidal </span>nucleus<span> called a macronucleus. Every paramecium must have at least one small </span>nucleus<span> called a </span>micronucleus. The micronucleus is a storage site for the germline genetic material of the organism.
