Answer:
A
Explanation:
Epipelagic zone is the one closest to the surface and is the best lit.
As the number of organisms increase so does their tropic levels. As one organism eats the other energy is being transferred to that organism. The larger the food chain the lesser the organism' s would be because they would lose energy while trying to hunt and catch their prey and other activities. The food chain usually ends at the tertiary consumer or the fourth link because if it goes on like that there would be less energy hence these organisms would most likely starve and gradually die.
Answer:
The correct answer is convergent evolution.
Explanation:
The wings of bats, butterflies, and most birds are the example of analogous structure. Analogous structures are the structures which are similar in appearance and function but have separate evolutionary origin.
They are similar superficially because they experienced a natural selection that evolved them to have that shape which helps them to fly. Analogous structures are produced due to convergent evolution.
Convergent evolution describes the presence of the same trait in unrelated species. Therefore the correct answer is convergent evolution.
Answer:
No because we need to observe the suspected parents karyotypes 6.
HOPE IT HELPS
Explanation:
Answer:
The correct answer is - 0.084
Explanation:
Sickle cell anemia is a autsmal recessive blood disorder of RBCs where RBC shape altered to the sickle shape or cresecent moon that obstruct and damage the veins and artries.
Normal allele is represented by - HbA - p
sickel cell allele is represented by - HbS - q
genotype frequency of normal allele HbA in the population = p2
genptype frequency of HbAHbS in the population = 2pq
genotype frequency of autosomal recessive HbS = q2 = 0.007 (given)
So, the allelic frequency of the recessive allele =
q = √ 0.007 = 0.08366 or 0.084
