Cell biologist, Dr. Martine Dinen, is observing an organism's cell using a transmitting electron microscope. She notices that wi
Assoli18 [71]

The cell is most likely prokaryotic because:

Prokaryotes lack membrane-bound organelles such as the nucleus due to which the DNA are seen throughout the cytoplasm.

Eukaryotes have membrane-bound organelles such as the nucleus. So for eukaryotes, the DNA will be present packed inside the nucleus instead of being dispersed in the cytoplasm.

Prokaryotes can either be autotrophic or heterotrophic depending on their mode of nutrition. Autotrophic prokaryotes can make organic molecules for a carbon dioxide source. On the other hand, heterotrophic prokaryotes can take carbon from organic compounds. Hence, the organism can be autotrophic or heterotrophic.

Natural selection relies on genetic variation. In any population of beetles, there are alleles for brown or green color. What ha
Savatey [412]

The correct order for natural selection can be summarized as:

1. Inherited variation: Individuals among the population exhibit inherited variation such as body color, body size, hair colors, voice properties, et cetera.

For example, the population of beetles: an equal number of green and brown beetles.

2. Competition: Organisms face the struggle for their survival.

For example, Natural habitat is in trees. Green leaves hide green beetles.  

The brown beetles are noticed by birds in the area.

Birds eat brown beetles.

3. Selection: It leads to differential reproduction, that is, the organisms with adaptive traits tend to survive and reproduce more.

For example, green beetles reproduce in greater number than brown beetles.

4. Adaptation: The organisms with survival traits tend to survive more and pass their traits to the future generation.

For example, more green beetles survive than brown beetles.

5. Evolution: The change in allele frequency of the population takes place.

For example, beetle population changes from brown and green to mostly green beetles.

Thus, the correct order would be:

1. The population of beetles: an equal number of green and brown beetles.

2. Natural habitat is in trees. Green leaves hide green beetles.  

3. The brown beetles are noticed by birds in the area.

4. Birds eat brown beetles.

5. Green beetles reproduce in greater number than brown beetles.

6. More green beetles survive than brown beetles.

7. Beetle population changes from brown and green to mostly green beetles
