Answer:
Short answer is primers are partially complementary.
Explanation:
Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3'
Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3'
When we write reverse primer 5' to 3' we can easily see that
3'-TTGGCCAATGG---5' is complementary to the forward primers'
5'---AACCGGTTACC-3' sequence. So instead of binding to the template DNA these primers might bind each other resulting with reduction of efficiency of DNA amplification.
Out of the choices given, the two Middle Eastern people that can be referred to as a Semite is the Jews and the Persians. This will make the correct answer D.

Answer:
The correct answer is hypophysis or pituitary.
Explanation:
The pituitary gland is at the size and shape of a pea and is also known as the master gland because it controls and stimulates the regulation of other endocrine glands. The pituitary gland is itself an endocrine gland which secretes its hormone directly in the blood.
Some hormones released by pituitary that stimulate other endocrine gland are adrenocorticotropic hormone (ACTH) which stimulate the adrenal gland to release cortisol. FSH and LH hormone that stimulate testes and ovary in male and female, Thyroid-stimulating hormone (TSH) which stimulate thyroid gland, etc. Therefore the right answer is pituitary.
