<u>Answer:</u>

Schwann cell is found in the central nervous system and it is named after the German scientist who discovered it. Schwann cells are initiated during any nervous injury and helps in the regeneration of the dead cell.  The DNA protein in the Schwann cell helps to revert the damaged cells back to their original form.

When an Axon gets distorted in the peripheral nervous system the myelin sheath is provided from the Schwann cells. Hence the absence of these cells will not induce the formation of new cell by resulting in deformed or immature repair.

3. In pea plants, flowers can be purple (P) or white (p). Purple is dominant to white. In a field of peas, you count 18 plants w
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

Dvinal [7]

Answer:

El problema es "¿Cuál es la capacidad de solubilidad de los cristales de yodo en diferentes tipos de líquidos?"

Explanation:

Solubilidad es el término que se refiere a la capacidad de las sustancias (solutos) para disolverse en presencia de líquidos (solventes). Así, podemos decir que si Luís quiere saber si los cristales de yodo se pueden disolver en diferentes líquidos, está intentando solucionar el problema de la capacidad de solubilidad de estos cristales.

En este sentido, podemos decir que el yodo no es una sustancia que se disuelva fácilmente en agua, pero sí se puede disolver fácilmente en cloroformo.

Each round of the citric acid cycle begins when the four-carbon molecule oxaloacetate is converted to the six-carbon molecule ci
Verdich [7]

Answer:

The added carbon is supplied by acetyl CoA and the 2 eliminated carbons are released as CO2.

Explanation:

TCA cycle or citric acid cycle occurs in the mitocondrial matrix.

           The ist step of TCA cycle deals with the formation of citrate molecule bt the addition of Acetyl CoA with oxaloacetate. The acetyl CoA is a 2 carbon compound formed from pyruvate by the catalytic activity of pyruvate dehydrogenase .

          The 2 eliminated carbons are released as carbon di oxide or CO2.The CO2 molecule is eliminated during the formation of alpha ketoglutarate from isocitrate .The second CO2 molecule is eliminated when alpha ketoglutarate is converted to succinyl CoA.
