Biology
1 answer:

Answer:

Because at some point in that food chain, the energy consumption has it's limit, and the predator will not have anything to hunt it. There is a limited amount of energy in a food chain that can go around, and once you reach the predator, that energy doesn't quite run out but it hits that limit where the chain has to repeat itself.

Which action is characteristic of the hormone vasopressin?
andriy [413]

ADH increases arteriole constriction and tubular permeability to water

Vasopressin, also referred to as antidiuretic hormone (ADH), is a hormone secreted by the posterior pituitary gland. Arteriole constriction and tubular permeability to water are both increased by ADH. Calcitonin and parathyroid hormone levels in the blood regulate calcium equilibrium (PTH). the hormone that aids in blood vessel constriction and aids the kidneys in regulating the body's salt and water balance. This aids in regulating both blood pressure and urine production.

Sensors (baroreceptors) in the heart and big blood vessels can identify a drop in blood volume or low blood pressure that happens after dehydration or a hemorrhage. These encourage the secretion of anti-diuretic hormones.
