Which steroid hormone(s) would not be produced if you blocked the activity of p450scc?

natka813 [3]

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.

Considering the definition of probability, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%

Probability is the greater or lesser possibility of a certain event occurring.

In other words, probability establishes a relationship between the number of favorable events and the total number of possible events.

Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.

$P(A)=\frac{number of favorable cases}{total number of possible cases}$

In this case, you know that in a moth population, 48 are brown, 30 are yellow, and 67 are black. So, the total number of possible cases is calculated as:

total number of possible cases= 48 + 30 + 67= 145

The number of favorable cases for a moth to be brown is: 48

Then the probability that a moth is brown is calculated as:

$P(A)=\frac{48}{145}$ = 0.33= 33%

On the other side, the number of favorable cases for a moth to be yellow is: 30

Then the probability that a moth is yellow is calculated as:

$P(A)=\frac{30}{145}$ = 0.21= 21%

In summary, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
