t is governed by an independently assorting hypostatic gene (Y) and green by its recessive allele (y). When dihybrid plants are crossed, the offspring appear in the ratio of 12 white : 3 yellow : 1 green. What fruit color ratio is expected from the cross of WwYy to Wwyy?
a) all white
b) 1/2 white, 1/2 yellow
c) 1/2 white, 1/4 yellow, 1/4 green

30. Which of the following describes homeostasis?
kozerog [31]

The answer is D. A boy’s heart rate increases when running. Why? First of all homeostasis is all about balance in one’s body. So you can’t immediately cross out answer choices: a, b , and e. Those don’t talk about keeping balance within someone or an organisms body. And you can also immediately eliminate answer choice C because that answer choice is talking about inheritance which coincides with genetics. Lastly the heart rate increase to cool the boy’s body temperature. It’s trying to reach the equilibrium of the body temperature since it’s no longer at balance since he started running. That’s why he starts to sweat (I know that it doesn’t mention that but you should kind of get that since he’s running). Swear cools down your body.

Explanation:

Glucocorticoids are hormones of the family of corticosteroids that participate in the regulation of carbohydrate metabolism favoring gluconeogenesis and glycogenolysis; They also have immunosuppressive activity. Its regulatory action also extends to the intermediate metabolism of fats and proteins. Glucocorticoids are mainly produced in the adrenal cortex of humans and are cortisol, cortisone and corticosterone. Cortisol is the most important glucocorticoid in humans.

From the pharmacological point of view they are corticosteroids for systemic use whose reference drug is hydrocortisone, which at high concentrations can suppress the production of ACTH adrenocorticotropic hormone in the adenohypophysis.
