Explanation:

A model illustrates the shape of the molecule and the orientation, in space, of the atoms that make up the molecule. This visualization enables the students to understand how the position of the atoms (beads) in the molecule and the different types of bonds (pegs) that join them. The interaction of the atoms (beads) and the bonds (pegs) between them affect the geometric structure of the molecule. This subsequently increases understanding of the molecule’s stereochemical outcomes of reactions.

Answer:

The one treated with DNase and protease

Explanation:

<em>The samples that will transform yellow into purple if RNA is the genetic material are the ones treated with </em><em>DNase </em><em>and </em><em>protease</em><em> respectively.</em>

<u>The treatment of the heat-killed sample of the purple life with DNase will ensure that the DNA in the sample becomes degraded while treatment with protease will ensure that protein is degraded, leaving only the RNA. Thus, the RNA can be taken up by the yellow life form and become transformed into purple if indeed RNA is the genetic material.</u>

The sample treated with RNase cannot transform the yellow life into purple because the RNase catalyzes the degradation of RNA into smaller components.

The image shows a bean-shaped bacterium with long tail-like projections streaming from it.
Leto [7]
I'd also say that the morphology presented in this picture is filamentous.
The reason for my believing this is that filamentous morphology concerns long visible chains, threads, or filaments, which you can see in the image.

Vedmedyk [2.9K]

Answer:   3- mutation, natural selection, migration

Explanation:

1-genetic drift, mutation, natural selection

2-mutation, founder principle, bottleneck effect

3-mutation, natural selection, migration (gene flow)

The correct answer for this question is" #3.mutation, natural selection, migration (gene flow)." The sequence of evolutionary mechanisms which have come into effect in each event is that of mutation, natural selection and migration. There is a steady rise in the population of bright-colored fish. Both populations thrive.
