Expert Solution

1. Childbirth is seen as a shameful event in some cultures only when the sex of the child is female. So, the statement is true. There are many backward regions and cultures where having a daughter brings shame to society so either they are killed as an infant or aborted.

2. The statement is false. The neurotransmitter is a chemical released by neurons (nerve cells) to stimulate neighboring neurons or muscle or gland cells, thus allowing impulses to be passed from one cell to the next throughout the nervous system and not the endocrine glands.

3. Option (d) is correct. Early in development, every neuron starts with the potential to become any specific type of neuron; what it becomes – how it differentiates – depends on where it migrates. Thus, if a neuron that would normally migrate to the visual cortex of an animal’s brain is transplanted into the area of the cortex that controls hearing, it will differentiate as an auditory neuron instead of a visual neuron.
