Puberty is caused by the release of follicle stimulating hormone and luteinizing hormone from the pituitary gland. These hormone
s are delivered to the ovary in girls and initiate the monthly release of mature egg cells. This is an example of what mechanism of regulation of gene expression? A. a typical signal transduction pathway
B. homeotic genes
C. induction
D. activation of micro RNAs
The onset of puberty in girls by the release of these two hormone is an example of typical signal transduction pathway
Explanation:
Specifically Luteinizing Hormone (LH) along with the Follicle stimulating Hormone (FSH) released from pituitary gland gets attached to the receptors present in the cells of ovary and generate a series of chemical reaction or cascade of biochemical reaction in a cell (activation of secondary messengers like cAMP) to produce estrogen and progestrone that will help in follicle formation and ovum maturation.
Option a, b and c are examples of not practicing proper hygiene and they increase the chances of you getting diseases. Option D is the only example that practices proper hygiene.
Explanation: The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days.
<span>There have been studies done that show using this technology to create milk makes the milk more dangerous. People who drink this milk are more likely to get prostate cancer, breast cancer and colon cancer. The technology also creates many toxins that can harm the cows and milk drinkers.</span>
