Answer:
The correct answer is D. Reduced levels of circulating estrogens.
Explanation:
Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.

of meiosis. The hypothalamus or the master gland in most animals, including
humans send signals to the ovaries and testes of the reproductive system. In
response to these signals, these ovaries and testes undergoes the sex cells
division which is called meiosis. Spermatogenesis in male gametes, is the
process of sex cell division among sperm cells. On the other hand, oogenesis is
for the female gametes. These cell divisions among respective gametes produces
haploid cell which only contain one pair of chromosomes, in number -23.
In response to this inquiry's question. Simply reproduction.
