An excitatory postsynaptic potential (EPSP)
a) depolarizes a neuron, increasing the likelihood of an action potential.
b) hyperpolarizes a neuron, decreasing the likelihood of an action potential.
c) hyperpolarizes a neuron, increasing the likelihood of an action potential.
d) depolarizes a neuron, decreasing the likelihood of an action potential.

A is the correct answer.

Explanation: If it is an EPSP, it increases the likelihood of an action potential. Therefore only A and C make sense. To fire an action potential, the neuron has to depolarize; therefore A is the correct answer.

its probably to later but whats the question

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
