Once retinal has absorbed a photon which initiates effects that create nerve impulses, the impulses get carried to the brain, which then processes the impulses along with other signals, ultimately allowing the eyes to see.
The energy needed by a system to initiate a process is called as the activation energy. It describes the minimum energy which must be available to a chemical system with potential reactants to result in a chemical reaction. Hope this answers the question.
<span>Antidiuretic hormone (ADH) is primarily regulated by the changes in plasma osmolarity. Any alteration in the plasma osmolarity is sensed by the osmoreceptors, which are the neurons present in the hypothalamus. They then, stimulate the secretion of ADH.</span>
People who are lactose intolerant are unable to digest lactose, the sugar commonly found in dairy, because their bodies don't make the enzyme lactase.
Lactase works by breaking down lactose into a simpler sugar that can be used by the body. Without it, lactose is not absorbed by the body & remains in the waste where gut bacteria metabolize it & cause the bloating, gas & other similar discomforts experienced by the lactose intolerant.
Hope that helps!
In truth, though, it is the non-lactose intolerant people that are the mutants. Not the other way around. Most wild animals don't consume milk after they have been weaned & it's just something humans developed to accommodate their diet.
