Alright my friend the answer to your question will be true let's put an example in to inform why it is alright so say you and your cousin look a like that's because the genetics are similar but not exactly the same
On the off chance that a change happens, if beneficial in the scarcest, normal choice picks it to wind up noticeably the more typical quality, and consequently development happens. For instance the dark demise wiped out one in three Europeans, now researchers are finding that some of the individuals who survived had transformations on their resistant framework cells; they needed regular receptors, or generally had few. (DNA resembles history, obviously, they aren't meeting with dark torment patients, the DNA in Caucasian Europeans goes about as an authentic guide of past bottlenecks.) Because Europeans with this transformation were to the least extent liable to bite the dust of the dark passing they were the well on the way to survive, which is the reason the calamity of the bubonic torment brought about somewhere in the range of 20% of Caucasian European relatives to do not have these receptors on their invulnerable framework cells which thusly diminishes the danger of resistance illnesses, for example, assistants.
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
