When chiasmata can first be seen in cells using a microscope, the following processes has most likely occurred in prophase I.

<h3>When chiasmata can first be seen in cells using a microscope?</h3>

Recombination can occur at any two chromatids within this tetrad structure.

Crossovers between homologous chromatids can be visualized in structures known as chiasmata, which appear late in prophase I.

Thus, option "C" is correct, Prophase I.

Who discovered that dna was the genetic material or transforming factor that could convert nonvirulent r-type streptococcus pneu
KatRina [158]
Discovery
               In 1928 it was discovered by Frederick Griffith in an experiment generally known as transformation.

Experiment
                 
 In his experiment he considered two strains of <em>streptococus pneumonia,</em> one was R-type which was non-virulent and cause no disease in mice, other was virulent and S-type which cause disease and at last death of mice.
This experiment was comprised of four steps which are as follow:

 Step 1:
           First he injected living strain of S into mice, after sometime mouce died.

Step 2:
          He injected living strain of R into mice, the mice alive as he did not got any disease.

Step 3:
         He injected heat killed strain of S into mice and mice remain alive.

Step 4:
           He mixed living R strain with heat killed S strain and then inject into mice. As a result the mice died.

Conclusion:
                  It was found that genetic material from heat killed S stain were transferred to living R (non-virulent) strain, as a result R become virulent and cause the death of mice.

describe the basic process of evolution by natural selection. Describe the underlying genetic basis and role of the environment
shepuryov [24]

Answer AND Explanation:

Darwin describes natural selection as a process whereby nature selects those organisms that have favourable characteristics to be parents of the next generation. The individuals possessing the favourable traits are better suited to the prevailing environmental conditions. This enables them to stand a better chance to survive in the struggle for existence due to limited resources.
