<h2>Instantaneous speciation;the formation of a new species over a few generation.</h2>
Explanation:
- This is a type of speciation where new species are produced which are separated from the parental individual by biological or geographical barrier.
- This type of speciation occur among individual and not in a population.
- It is a kind of sympatric speciation which is caused by poliploidy.
The segments of DNA that contain the code for specific proteins are called, genes.
The bacteria shown in the figure has been magnified ten thousand times, as indicated by the value of the magnification factor.
<h3>What is the magnification of an object?</h3>
When examined using a magnifying device such as a microscope, the size of an item seems to have expanded by a certain degree or quantity. This phenomenon is referred to as the magnification of the thing in question.
Magnification = size of the image/size of the actual object
Therefore

Therefore
2.0 µm = 2.0 * 1/10 000 cm
= 2.0 * 10^{-4} cm
Hence, Magnification
M= 2.0 cm /2.0 * {-4} cm
M = 10000 X

Answer:
S phase is called as DNA synthesis phase.
In G1 Phase the DNA replication Begins.
During G2 phase cell grow rapidly and protein is synthesized and cell prepares itself for mitosis.
During Mitotic (M) phase, cell division occur.
spermatogenesis is the process during which the production of male sperms occur.
In oogenesis the female egg is produced. Further explanation in attached figures.
