When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.

Answer:
a) All Walnut , Genotype - RrPp
b) Walnut : Rose: Single
1:1:2
Explanation:
Phenotype and their Genotype -
Walnut comb - R_ P_
Rose Comb - R_ pp
Pea Comb - rr P_
Single Comb - rr pp
a) RR PP * rr pp
All progenies will have genotype RrPp (Walnut Comb)
b) Rr Pp * rr pp
RrPp (4), Rrpp (4), rrpp (8)
Walnut : Rose: Single
1:1:2
Answer:
The correct answer is 4,960,000
Explanation:
If a yeast cell divides into two yeast cells in 120 minutes that means a yeast cell needs 2 hours to get double. So according to the question 2 hours ago a yeast colony consisted of 310,000 cells that means the present colony should have 620,000 cells.
So after six hours from now, this population will divide three times in six hours because the generation time of yeast cell is 2 hour and each time the number of cells will double.
Therefore, in first time the number will increase to 1,240,000(620000*2), the second time the number will increase to 2,480,000(1240000*2) and after final division, the number will be 4,960,000(2480000*2).
Therefore after 6 hours from now, the approximate number of yeast cells will be 4,960,000.
