<h2>Answer:</h2>

The two reasons are given below:

  • Natural selection.
  • Lack of food
<h3>Explanation:</h3>

Natural selection is the phenomenon of the evolution in which the organisms able to fit in the changing environment survive while other organism died. Hence the survival if the fittest and then these organisms. Further reproduce to give birth organisms more fit to the changing environment.

The long neck giraffe survive but short neck died. So the population of long neck increased while short neck go extinct.

Other reason is the change of food resource. The food resource change from grass to long trees.

In all cells, separation of replicated chromosomes is a prerequisite for cell division. However, the mechanism of chromosome sep
Ipatiy [6.2K]

1. two copies of the duplicated chromosome are attached at their centromeres before separating

2. chromosomes replicate before cell division

3. chromosome separation begins at the origin of replication on DNA

4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation

5. replicated chromosomes separate by attaching to some other structural feature of the cell

Explanation:

In the given question, the DNA replication steps of both prokaryotes and eukaryotes are provided in which some are common to both eukaryotes and prokaryotes and some are unique to the prokaryotes and eukaryotes.

<u>Eukaryotes </u>

1. Option-4 as the nuclear envelope is present in eukaryotes only.

2. Option-1 as centromere allows the kinetochores bind to the centromere which separates the chromosome.

<u>Bacteria </u>

1. Option-3 as DNA replication process separates the strand of the DNA.

<u>Both </u>

1. Option-5 as the chromosomes separate by other structures like microtubules

2. Option-2 as genetic material to be passed on to the generation must be replicated.
