Select one:

a. It would likely have no effect on her ability to form a bond

b. It would make forming a bond more difficult

c. It would make forming a bond easier

Answer 1

1. a true

Spinal cord injuries at the level of neck block the relexogenic pathway leading to sexual arousal of the genetic is true because the injuries caused in the neck region block the transmission of message in the region of brain and damage the lower level of the tissue which result in sexual arousal.

2. a True

The faces of healthy people are generally a little assymetrical this statement is true

Reason: Every individual has little assymterical faces because in some condition it occur just during the development.sometimes exposure to the climate change result in assymterical faces, lifestyle of the individual is also one of the reason.

3. C GnRH release would decrease

Reason :if the pituitary gland is removed from a men it would result in decrease in GnRH level because pituitary gland control the function of the testiclese, as pituitary gland function is to produce hormone testes and growth hormone so removal of pituitary gland result in decrease in GnRH.

4b is correct

Viagra block the phosphodiesterase 5 which result in production of a smooth muscle relaxant which result in the inflow of the blood level in Corpus carvernosum.T enzyme help in the breakdown of the cGMP and the level of cGMP gets increase.

5.c it would make forming a bond easier.

Reason according to Aragon's team members they have discovered that if the dopamine is injected into the nucleus acumbens results in the pair bond formation.
