What effects does crossing<br> over have on a chromosome?
FinnZ [79.3K]

Answer: crossing over allows for genetic variation

Explanation:

crossing over is the exchange of genes between two chromosomes which ends up resulting in non-identical chromatids that comprise the genetic material of gametes (sperm and eggs).

Basically crossing over makes the chromatids that are held together by a centromere, no longer identical to eachother which creates genetic variation.

Calcium levels in the body are maintained by hormones. If the blood calcium level rises above a set point, calcitonin is secrete
Tanya [424]

Calcium levels in the body are maintained by hormones. If the blood calcium level rises above a set point, calcitonin is secreted by the thyroid gland and sets into motion responses to lower the blood calcium back to the set point. If the blood calcium level falls below a set point, the parathyroid gland secretes parathyroid hormone that sets into motion responses to raise the blood calcium. These homeostatic responses are examples of:

a. positive feedback

b. effectors

c. sensors

d. negative feedback

Answer:

d. negative feedback

Explanation:

Negative feedback responses are the ones that counteract the change. Any alterations in the internal body conditions such as blood calcium levels are sensed by receptors. The information is sent to the brain which in turn commands the effectors such as endocrine glands to secrete the required hormones to restore the normal conditions. Here, changes in the calcium levels are counteracted by the secretion of calcitonin and parathyroid hormones and the calcium is maintained within a narrow range. This represents negative feedback.
