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.

Explanation:
Glycogen is the process of storing excess glucose. During fight or flight, catabolism is the fore action of the body. Production of glucose for release of energy not conservation of energy.
Answer:
<em>The nutrient cycle </em><em>is nature's recycling system. All forms of recycling have feedback loops that use energy in the process of putting material resources back into use. </em><em>Recycling</em><em> in ecology is regulated to a large extent during the process of decomposition.</em><em> Ecosystems employ biodiversity</em><em> in the food webs that recycle natural materials, such as mineral nutrients, which includes water. </em><em>Recycling in natural systems</em><em> is one of the many ecosystem services that sustain and contribute to the </em><em>well-being</em><em> of human societies.</em>

Isotonic solution.
Since it has the same salt concentration as the cell the solution is neither hypotonic or hypertonic.
