The origin of congenital adrenal hyperplasia occurs when circulating cortisol levels are low.
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease which results from mutations of genes for enzymes involved in the biochemical steps of production of mineralocorticoids, glucocorticoids or sex steroids from cholesterol by the adrenal glands (steroidogenesis). <span>Low cortisol production results in rising levels of ACTH (adrenocorticotropic hormone) because cortisol usually inhibits ACTH production. This increased ACTH production induces overgrowth (hyperplasia) and overactivity of the steroid-producing cells of the adrenal cortex.</span>
Answer:
the average annual rainfall.
Explanation:
It is defined as the annual amount of precipitation for a location over a year.
Fresh water community obtained its storage as precipitation from the atmosphere of rain, mist and snow..
The amount of rainfall of a community depends on the location.A typical rain forest receives average of 50,- 260 inches of rain per year.
The correct answer is option B. Wind-pollinated plants rely on large quantities of pollen grains.
The plants, which pollinate by wind spend less energy in creating attractive structures to attract pollinators, instead they produce many pollen grains, which are light and easy to carry by winds. the pollens are usually dry.
The angiosperm mostly rely on animal pollinator and they have large colorful flowers, which produce nectar to attract the insects or other animals.
Tropical rainforests biome are typically hot and wet.
B because I’m pretty sure only whales and dolphins have blowholes
