Which of the following electrical events is characteristic of inhibitory synaptic interactions?

#SCPH28 | Zoology
  1. A neurotransmitter agent that selectively opens ligand-gated chloride channels is the basis for an inhibitory postsynaptic potential
  2. Because the Nernst potential for chloride is about −70 mV, chloride ions tend to move out of the cell along its electrochemical gradient
  3. A neurotransmitter that selectively opens potassium channels will allow potassium to move into the cell
  4. An increase in the extracellular sodium concentration usually leads directly to an inhibitory postsynaptic potential

#SCPH12 I Genetics

In humans, albinism (unpigmented skin, hair, and eyes) is due to an enzymatic deficiency, and it is an autosomal recessive trait. Suppose that in a small country of one million people (“Generation 1”), there are 500 aa albinos and 9000 Aa heterozygous carries. If the Generation 1 follow the Hardy-Weinberg equilibrium?
a) then the number of homozygous aa albino individuals would be equal to P2
b) there were 500 albino individuals in generation one.
c) then the number of homozygous aa albino individuals would be equal to q2
d) there were 25 albino individuals in generation one.
Which of the following is the correct prediction about the hardy-weingburg equilibrium?
