const2013 [10]

Answer:

a) p=0.665

b) q=0.335

c) 2pq=0.445

d) (0.665^2)+(0.335^2)+(2*0.665*0.335)=1

Explanation:

For solve this exercise I will use the Hardy-Weinberg principle. We have the following:

a) and b)

number of purple flowers=142

number of white flowers=18

total number of flowers=160

frequency of white flowers=q^2=18/160=0.112

q=0.335

if

p+q=1

Clearing p:

p=1-0.335=0.665

c) the heterozygous is 2pq:

frequency of heterozygous allele: 2pq=2*0.665*0.335=0.445

d) p^2+2pq+q^2=1

(0.665^2)+(0.335^2)+(2*0.665*0.335)=1

Cells A and B receive the same high levels of stimulation, but Cell A shows a lower level of activity relative to Cell B. A like
Hitman42 [59]

Answer:

Cell A is laterally being inhibited by other neighbouring cells.

Explanation:

Cell A showing lower activity compare to cell B despite both having high simulation is because Cell A is surrounded by neighbouring cells and these neighbouring cells hinder the action potential of cell A through their numerous activity they perform around cell A.

Therefore they restrain the activities of cell A.
