DiKsa [7]

Answer:

The answer is b. Both of them are characterized by selective permeability.

Explanation:

Option a. states that both, the nuclear and the cell membrane have two layers. This is only true for the nuclear membrane that consists of two lipid bilayers whereas the plasma membrane only contains one layer.
c. Only the nuclear membrane has nuclear pores that connect the two bilayers. The pores act as protein channels or passages that allow transport of materials. The cell membrane does contain channel proteins or transmembrane proteins but not protein channels.

tatyana61 [14]

Answer:

A nerve impulse from one neuron affects the activity of a neighboring neuron at a point of interaction called the: SYNAPSE

Explanation:

A NEURON(or nerve cell) has 3 parts:

1. The dendrites(multiple)

2. The axon

3. The cell body

A SYNAPSE is an area where the dendrites of one neuron communicates with the axon of another neuron.

At the synapse, nerve impulses are transmitted from one neuron to the other. This is possible through substances called NEUROTRANSMITTERS. There is no direct contact between the axon of one neuron and dendrites of another neuron.
