Answer:
A
Explanation:
in a relationship a parasite is described as the member who greatly benefits in the relationship at the other's expense.
Like riding a stubborn horse, when it bucks you off, it gets the pleasure from doing so, but you end up with a broken foot.
The host is who hosts the other, and the tapeworm is attaching itself to a host so the answer must be A
cannot be b since no proof of that relationship, in both c and d the bass is caused harm so it is not mutual or beneficial to the bass in any way

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.
