Answer:
Mitosis is a type of cell division in which a parent cell divides into two identical daughter cells, each with the same number and kind of chromosomes as the parent cell.
When a parent cell divides more times than usual during mitosis, the division of chromosomes between the chromosomes would not be proper. For example, a daughter cell may end up with one chromosome less than the parent cell. This ultimately results in genetic disorders.
Answer:

Explanation:
As we know that rms speed of ideal gas is given by the formula

here we know that

molecular mass of gas is given as

now from above formula we have

now we have

The correct answer is A. Most reactive non metals.
Firstly if some one knows how to read the periodic table he would have no confusion in deciding whether group 7 has metals or non metals. Group 7 contains non metals so basically we can easily cancel out two options of metals.
Secondly group 7 non metals are the most reactive non metals as they need only one electron in order to complete their valence shell and become stable.
