The primary reason that osteoporosis accelerates after menopause in women is: * 2 points A. Increased osteoblast activity. B. Re
Nutka1998 [239]

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.

Explain why the formation of abscission layer causes sugar to accumulate in leaves.
kramer
Abscission layer is the layer of cutinized parenchyma cells that develops in the abscission zone. The abscission zone form across the base of the plant part, where the break eventually occurs.

aleksklad [387]
<h2>The Forearm</h2>

Explanation:

The proximal end of the radius illustrates the relationship of form and function. The cup-like surface of the radial head articulates with the rounded shape of the capitulum. This forms a joint that allows for movement of elbows and forearms.

Radius and ulna are the two bones of the forearm.  Their proximal ends articulate and fit into the cup like end of the humerus. This forms a synovial joint called the elbow joint.  The movement of this joint allows the forearms to supinate and pronate.

Which of the following is not a way that sexual reproduction increases genetic diversity?
cricket20 [7]

Answer:

Combined parenting leads to faster reproduction

Explanation:

Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.

During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.

Fertilization permits parental genes to be brought together. This causes variations in members of the same family.

Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
