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.
- d. The nuclear membrane separates nuclear contents from the cytoplasm whereas the cell membrane separates cellular contents from the extracellular environment.
 
        
             
        
        
        
Gunter will be undergoing functional Magnetic Resonance Imaging (fMRI).
This technique for brain activity measuring is based on the fact that cerebral blood flow and neuronal activation are coupled. Blood flow increase in an area of the brain that is in use.
 
        
             
        
        
        
The carrying capacity is impacted by both biotic and abiotic processes. The carrying capacity develops as these conditions improve. The carrying capacity decreases as the factors grow scarcer. When resources are depleted faster than they are replaced, the species has reached its carrying capacity.
<h3>What is carrying capacity?</h3>
The average population size of a species in a given habitat is referred to as carrying capacity. 
Environmental considerations such as appropriate food, shelter, water, and mates limit the species population size.
The carrying capacity is impacted by both biotic and abiotic processes. The carrying capacity develops as these conditions improve. 
The carrying capacity decreases as the factors grow scarcer. When resources are depleted faster than they are replaced, the species has reached its carrying capacity.
Thus, in this way abiotic factors and biotic factors affect population growth.

Answer: 
A story that might be a good human interest story would be the vaccines for corona. Everyone these days are waiting desperately for corona to end. Talking about a vaccine might give them hope, and it would be nice to see how the scientist and doctors truly care for the people. Maybe encourage them to wear the masks until the vaccines come out?
