Answer:

D) Pressure potential differences between source and sink

Explanation:

high turgor pressure causes the movement of   phloem sap from source to sink, Sap moves through phloem via translocation, the transport of dissolved materials in a plant. Unlike the xylem, which can only carry water upward, phloem carries sap upward and downward, from sugar sources to sugar sinks.

The origin of congenital adrenal hyperplasia occurs when circulating cortisol levels
LuckyWell [14K]
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>

How many calories are in an average trick-or-treaters halloween stash?
Vera_Pavlovna [14]

The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.

Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.

Considering this, in a Halloween stash the calories depend on two factors:

  • The types of candies or products
  • The units of each one

Let's suppose there are 5 units of each of the following candies:

  • Chocolate bars
  • Taffies
  • Lollypops
  • Candy corn

Let's now calculate the calories

  • Chocolate bars = 220 calories x 5 units =  1,100 calories
  • Taffies = 20 calories x 5 units = 100 calories
  • Lollypops = 83 calories x 5 units = 415 calories
  • Candy corn = 7 calories x 5 = 35 calories

Add all the previous results:

1,100 + 100 + 415 + 35 = 1,650 calories in total
