Answer:
Most animals in the rainforest live in the canopy. The layer below the canopy is called the understory. Small trees and plants that do not need much light grow here. The last layer is the forest floor where only a few plants grow because it's so dark.
But in the tropical rainforest, plants grow so fast that they rapidly consume the nutrients from the decomposed leaf litter. As a result, most of the nutrients are contained in the trees and other plants rather than in the soil.
Explanation:
Answer:
i think oxygen from the surrounding is,obtained through the plasma membrane of an earth worm by the process called diffusion
Dominant genes will come before recessive. Someone with brown-eye and blue-eye genes will have brown eye since it's the dominant one. So sometimes blue -eye allele is hidden because it's not express, but not always.
People with blue eyes must have all blue-eye allele. Therefore, if there are people with blue eyes you can conclude that blue-eye allele has not disappeared in the human population.
If there is no factor that intervenes with population breeding, Hardy-Weinberg equilibrium will be maintained and that can be used to explain why the <span>all the blue-eye alleles have not disappeared in the human population</span>
