Answer:

Gene flow prevents  reproductive isolation of populations and prevents speciation.

Explanation:

Speciation is the process of formation of new species from the existing ones. Two species are reproductively isolated and cannot interbred to produce fertile progeny. Gene flow is exchange of alleles between local populations and does not allow them to become reproductively isolated. Since the two populations can interbreed, they cannot form two separate species.

What is the weakest part of a developing, adolescent long bone?
shutvik [7]

Answer:

The weakest part of a long developing and adolescent bone is called growth cartilage (epiphyseal plate)

Explanation:

Both children's bones and adults' bones are at risk of injury. However, in the case of bones in a child, they are subject to an injury known as a growth cartilage fracture or epiphyseal plate. These growth cartilages are areas that are in full development in the vicinity of long bones. Its function is to help establish the length and shape of the bone in the process of maturation. The growth of a long bone happens from the end next to the growth cartilage. In adulthood, these growth cartilages are strengthened forming the bone.
