How the combination of electrons, protons ans neutrons results in the neutral charge of an atom?
balandron [24]
Hi :D
Neutrons are neutral so they have no charge. Electrons have a negative charge and protons have a positive charge.
For an atom's charge to be neutral there has to be an even amount of protons and electrons in the atom.

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.
