Answer:
Water is taken up through the xylem until it reaches a leaf, where it diffuses out into the surrounding mesophyll cells. Water diffuses from the mesophyll cells to the surrounding intercellular air spaces as water vapour, and finally, out of the leaf through the stomata.

Answer:
an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment
Explanation:
An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.
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>
