Answer:
The frequencies would be - AaBb= 2/4= 1/2.... Therefore AaBb= 50%
- aabb= 2/4= 1/2.... Therefore aabb= 50%
Explanation:
The resulting F1 cross, AaBb, indicated that A is dominant over a, and B is dominant over b. Therefore a cross between AaBb and aabb would result to---
AaBb x aabb
= AaBb AaBb aabb aabb
Answer:
Option A, Glucose metabolism in the fetal brain increased
Explanation:
Usage of cocaine during pregnancy is prohibited. However, in case if cocaine is taken it disrupts the metabolism as it increases brain glucose metabolism to the level of an adult human being. Since glucose metabolism in brain is a sensitive process, any disruption in it can lead to unaccounted effects such as dysfunctional circulation, and pharmacological effect. Cocaine increases the dopamine by blocking the dopamine transporters thereby increasing the Vmax. Since the brain of a child has all kind of neurochemical components, cocaine intakes by a pregnant woman produces reinforcing effects in brain of fetus and also make it pharmacologically active
Hence, option A is correct

Answer: Here you go
Explanation: nerves (cranial, spinal, and peripheral) and neurons (sensory, motor)
Answer:
Myelination
Explanation:
Myelin is a fatty substance composed of lipids which surrounds the axons of the nerve cells in the central nervous system. The myelin is formed by the oligodendrocytes in CNS and Schwann cells in PNS.
The plasma membrane of the oligodendrocytes containing the myelin covers the axons of the neurons in spiral fashion thus proving a sheath around through the process called "myelination".
This myelin sheath protects the neurons from the external environment as well as insulates the neuron which increases the efficiency of the impulse.
Thus, Myelination is the correct answer.
