g If a pair of sister chromatids fail to separate during anaphase II (meiosis II), what will be the chromosome number of the fou

r resulting gametes with respect to the normal haploid number (n)

Answer:

The result will be two gametes with a normal haploid number (n), one gamete containing an extra chromosome (n + 1) and one gamete missing one chromosome (n − 1).

Explanation:

Nondisjunction is caused by the failure in the mechanism of separation of homologous chromosomes or sister chromatids during meiosis and/or mitosis. The failure in the separation of sister chromatids during meiosis II is referred to as 'secondary nondisjunction' and it produces two daughter cells with abnormal chromosome numbers.  

The fusion of one gamete containing an extra chromosome (n + 1) with a normal (n) gamete will lead to trisomy (2n + 1), while the fusion of one gamete missing one chromosome (n - 1) with a normal gamete will lead to monosomy (2n-1).

Answer:

They evolved from entirely different ancestors, but both developed wings in response to similar ecological conditions.

Explanation:

Based on the info given, they possibly could have had the same ancestor, but even if that was true, the bat would have some type of resemblance other than wings. I think that due to environmental changes, natural selection allowed these organisms to fly so they can survive in that environment. Birds got feathers because they could have been in a cold ecosystem so they needed warmth for themselves and their young as well as stay away from predators, due to their small size they had no way to get away without wings. They didn't have legs for running so they developed wings. Bats may have been in a fine temperature, but the day caused problems due to hunting, so they developed wings to hunt at night and keep themselves in caves to hide from predators.

This is the best I could do, I hope this helped :)

This is the process of changing energy from one form to another. Solar energy is changed into chemical energy by plants.
Colt1911 [192]

Answer:

Energy Transformation

Explanation:

The conversion of energy from one from to another is known as energy transformation.

Energy can only be converted or transferred from one object to another or to a different location but it can never be created from scratch. A good example is given in the question that solar energy is converted into chemical energy with the help of plants.

I hope the answer is helpful.

Thanks for asking.
