Answer:
B. Black Squirrels have a survival advantage over gray squirrels
Explanation:
Using the information provided, it can be inferred that there is a difference between how many Gray squirrels and how many Black squirrels are being naturally selected.
This means:
Black squirrels have an advantage that reduces the amount of squirrels being selected from their environment.
Hope this helps!
Answer:
B. a food chain
Explanation:
Food chain: a hierarchical series of organisms each dependent on the next as a source of food.
There should not be any changes in the gene pool.
In Hardy-Weinberg equilibrium, the gene pool should have a constant rate. The equilibrium can be achieved if there is no factor that favors one gene more than the others. Since the genes have the equal chance to survive and mating, the ratio of the gene pool should not change dramatically.
Answer:
The correct answer is option a, that is, cerebellum.
Explanation:
Alcohol acts as a CNS depressant. When more amount of alcohol is taken and the levels of alcohol rise within the body, some sections of the brain get influenced and a reduction in the functioning is witnessed in that particular part.
The region of the brain accountable for coordinating movement and also some kinds of learning seems to be sensitive specifically to the consumption of alcohol. Thus, cerebellum is the part of the brain, which gets most affected due to the consumption of alcohol. Therefore, test is performed to witness the balance of an individual, as cerebellum is the part of the brain responsible for appropriate posture and balance.
Answer:
The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype
