Answer:
Lateral inhibition.
Explanation:
Lateral inhibition may be defined as the ability of an excited neuron to reduce or decrease the activity of ts side by or neighbor's neuron. The sensory [perception is increased during lateral inhibition.
The stronger response is detected at the surface edge rather than on the cell's middle surface. The excited neurons move in the lateral direction and decreases the activity of the middle or neighbor neurons.
Thus, the answer is lateral inhibition.
 
        
             
        
        
        
Answer:
photosynthesis process uses the sun's energy to combine carbon dioxide and water to form glucose, a sugar. Carbon dioxide enters plants through tiny pores in the bottoms of leaves or by diffusion through cell membranes in the case of algae and protists.
 
        
             
        
        
        
Answer:
Farming enabled people to grow all the food they needed in one place, with a much smaller group of people. This led to massive population growth, creating cities and trade.

Answer:
Explanation:
My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene. 
B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee. 
Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.
