The question has been answered itself but the answer will contain the detail explanation.
Answer:
1. The replication fork formation during DNA replication is important for the continuity and the addition of the further base pair on the template. The DNA initiation process starts by the formation of replication fork.
2. The okazaki fragments are the short DNA fragments that are formed on the lagging strand. These fragments are later joined by the enzyme DNA ligase.
3. Leading strand is the continuous strand that formed during the DNA replication. The direction of the leading strand is 5' to 3' .
4. DNA polymerase is the main replicating enzyme during the DNA replication process. Different types of DNA polymerase with multiple subunits are present in prokaryotes and eukaryotes.
5. The new DNA that are formed from the parental strand and complementary with each other are called daughter DNA.
Mitosis
Explanation ~ Mitosis creates two daughter cells each having the same number and kind of chromosomes as the parent nucleus
By being in the same area or Causing weathering at the same time or place

<h2>Fixation</h2>
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
<h3>Biologically: </h3>
Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
<h3>Through lightning: </h3>
Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.

Explanation:
gene flow is a movement of the genes in or out of population. This movement can be caused by the migration of organisms that reproduce in the populations. Or the movements of the gametes
