P450scc or cholesterol side chain cleavage enzyme is an enzyme that converts cholesterol into pregnenolone (the precursor for steroids). The kinds of steroid hormones are mineralocorticoids (i.e. aldosterone) glucocorticoids (i.e. cortisol), and sex steroids (i.e. testosterone, estrogen). In the event where P450scc is blocked, then there will be no production of mineralocorticoids, glucocorticoids, and sex steroids. There will be no production of aldosterone, cortisol, estradiol, testosterone, and progesterone. This disease is called Lipoid Congenital Adrenal Hyperplasia.
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
The right answer is <span>A) semi-permeable membrane
<span>A semi-permeable membrane is a membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute).
</span>The tubule of a kidney consists of a semi-permeable membrane and has also specific transporters which allow absorption and reabsorption. These "tools" allows some substances like ions to be absorbed/reabsorbed (by the transporters), without any changes in the concentration of the other substances (because both the membrane and the transporters stopped them).</span>
Answer:
They main difference is in chemical composition and particle size. Silt is composed of silicate minerals, or those containing silicon and oxygen. Clay is composed of metal silicates, or silicates with metals like magnesium or aluminum associated with it.Clay particles are extremely fine — smaller than 0.002 mm. Sand particles are 2.00 to 0.05 mm in diameter
Explanation: Basically, the main difference is their size.

One way streets have unique features including all vehicles pointing in one direction. The street also has no yellow center line marks. A one way street is a street that has either a one way traffic or designed to direct vehicles in one direction and that is why it has those features.
