Answer:
The correct answer is- hormone signal amplification
Explanation:
The signals that are received by the cell can be amplified in the cell which results in the production of more than one molecule of the product. There is a signal pathway in every cell and the longer the signal pathway the more amplification chances are there.
For example, one membrane receptor is able to produce 10 secondary messengers and each secondary messenger generates 10 mRNA transcript so here the signal amplified by 1000 folds.
So in this question, it is seen that a small amount of releasing factor causing the release of a much greater amount of cortisol which shows the example of hormone signal amplification.
Answer:
Stratum Granulosum
Explanation:
The stratum granulosum is a layer of the epidermis and consists of four to six cell layers. The keratinocyte appearance changes in the cell layers of stratum granulosum as some cells stop dividing and the process of keratinization starts. Keratinization includes filling the cells with the protein keratin. During keratinization, the cells flatten, and the disintegration of their nuclei and organelles occur.
Due to the loss of the nucleus, these cells cannot divide and become dead. The keratinized cells accumulate keratohyalin granules and lamellar granules. The cells of this layer have thick plasma membrane due to the binding of cytosol proteins bind to the inner membrane face and coating of the external surface of the membrane by lipids of lamellar granules.
The duplication of centrioles occurs at the same time as DNA duplication for the cell cycle; that is, in the S phase of interphase.
The Meiosis Gizmo is an intuitive movement, which helps understudies through the steps of meiosis offspring utilizing crossovers and meiosis.
<u>Explanation:</u>
It explains how sex cells division that produces reproductive cells in sexually reproducing organisms produced by the process of meiosis. Compare meiosis in male and female germ cells, and use hybrids to expand the number of conceivable gamete genotypes.
Utilizing meiosis and crossovers, create "designer" fruit fly offspring with wanted attribute mixes. During meiosis, a few chromosomes swap portions of themselves, making new blends of qualities and expanding the hereditary decent variety of the sex cells.
