The right answer is C.

A gland is an organ capable of synthesizing a substance that will then be secreted. The endocrine glands secrete hormones, which will be released into the bloodstream with a role in communication between cells. This is, for example, the pituitary gland, the thyroid, the adrenal glands. The exocrine glands, such as the salivary or lacrimal glands, but also the mammary, sebaceous or sweat glands, produce substances that will be released into body cavities, or outside these cavities.

The correct answer is option C. Endocrine glands secrete hormones into the bloodstream because endocrine glands are ductless and the exocrine glands have ducts so they secrete their hormones into the ducts.

Answer:

P = 0.79.

Explanation:

To solve this, we need to understand the Hardy-Weinburg equation and what each variable is. P is usually used for the dominant trait classification (in this case, it would be long legs) and Q is usually used for the recessive trait classification (in this case, it would be short legs).

Therefore, we know that the values have to add up to 1 and that Q is recessive and P is dominant. So, if we begin applications, we can learn that to equal 1, we must use numbers less than 1 to accomplish this.

If 21 of a 100-person population have short legs, then ideally, 79 people would have long legs (the dominant trait). So, we know that 0.21 as q and 0.79 as p would equal 1 if you just added p and q together. Therefore, we can know that q is 0.21 and p is 0.79.

To prove this, we can insert these values into the equation:

$0.79^{2} + 2(0.79*0.21) + 0.21^{2} =1$

$0.6241 + 0.3318 + 0.0441 =1$

$1=1$
