Answer:
They are killed by predators for energy
This will result to an excitatory postsynaptic potential ((EPSP)
Neurotransmitters are those chemical messages that transmits signals from nerve cells to their target cells.
Neurotransmitters are packed inside vesicles at the presynaptic nerve terminal.
The arrival of an action potential at this terminal leads to opening of Voltage gated channels.
This leads to a change in membrane voltage of the postsynaptic cell following the influx of positively charged ions (sodium ion) into the cell which is called the excitatory postsynaptic potential.
Therefore, excitatory postsynaptic potential ((EPSP) occurs when a neurotransmitter opens a chemically gated ion channel that allowing sodium to enter the postsynaptic cell.

Answer:
5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)
6.) Frequency of R: 0.5
7.)Frequency of R: 0.5
8.)Frequency of R: 0.375
Explanation:
5.) If R and B code for the different forms of the same protein then they are only a few possible out comes
6.) First calculate the total alleles in population
allele R= 40
Allele B=40
total allele = R+B= 40+40
=80
Now to find allele R frequency is:
(Total R alleles) / (Total allele in pop)
40/80=
0.5
7.)Calculate the total alleles
Alleles from for R
RR= 10
R=10x 2= 20
Multiply the value by 2 because there are 2 R alleles present in
RB=20
R=20
Number doesn't change there is only 1 R allele
Total R=20+20
=40
Alleles For B
BB=10
B=10×2
=20
Same thing here, two B alleles together so multiple by 2
RB=20
B=20
Total B= 20+20
=40
Total alleles in pop add
40+40
=80
Frequency of R
Total of R/Total Alleles
=40/80
=0.5
8.)Repeat the same thing in 7 but use different numbers
RR=10
R=10x2
=20
RB=10
R=10
Total R= 20+10
=30
