The correct answer is: C) the random and independent way in which each pair of homologous chromosomes lines upat the metaphase plate during meiosis I
Independent assortment is the second Mendel’s law which states that the alleles of two/more different genes are sorted into gametes independently.
When homologous pairs line up during the metaphase at meiosis I they do that random. This means that formed gametes will get different combinations of "mom" and "dad" homologues and consequently, different alleles on those homologues.
The right way to write scientific names is: "<em>Genus</em> <em>specie"</em>. So, the right name is: "<em>Drosophila melanogaster</em>", letter b)

Answer:
150 - 300 bp
Explanation:
Micrococcal nuclease, indistinctly from the time of treatment and in average organisms, will realize the cuts on DNA o RNA zones rich in AT or AU. It is not a specific endonuclease.
Even so, the mean size of the expected fragments will have between 150 bp and 300 bp.
It is very important to run your digestion along with a proper label.
Answer:
Predators are an important part of a healthy ecosystem. Predators remove vulnerable prey, such as the old, injured, sick, or very young, leaving more food for the survival and success of healthy prey animals. Also, by controlling the size of prey populations, predators help slow down the spread of disease.
