Why are non-native species dangerous to ecosystems?
Vesnalui [34]

Answer & explanation:

Non-native species may be animals, plants or microorganisms introduced into an ecosystem of which they are not originally part, but where they adapt and come to dominate, harming natural processes and native organisms.

When a new species is introduced into an environment other than its own, it may compete with others, prey heavily on some species, over-breed and even cause disease.

Therefore, it can be concluded that this action may cause the destruction of some species, directly affecting the balance of that ecosystem.

zhenek [66]

Answer:

The answer is mother in meiosis II

Explanation:

nondisjunction can be defined as the failure of the segregation of the child chromosomes in meiosis I and meiosis II resulting in gametogenes. This results in abnormal gametes with some chromosomal imbalance being formed and subsequent fertilization of these gametes results in a generation of abnormal individuals.

According to exercise, red-green color blindness follows an X-linked recessive pattern and the phenotype is only expressed. the father cannot bring the possibility of color blindness to his children, and the nondisjunction, defined earlier, cannot occur in either meiosis I or meiosis II. As a conclusion we can say that it may have a place in meiosis I or meiosis II corresponding to the mother and although the mother's condition may be normal, the first child would be compromised with color blindness, therefore, the mother is the carrier.
