In Mitosis, one parent cell divides into 2 daughter cells with identical chromosomal number. However, in Meiosis, one diploid parent cell divides into 4 haploid daughter cells.

In each segment of the circle, multiply the outer two numbers together and subtract the sum of the outer two numbers in the opposite segment to give the value in the  inner grey segment

Hence, the missing number iss 25.

A conjugate acid, is a species formed by the reception of a proton (H+) by a base—in other words, it is a base with a hydrogen ion added to it.

On the other hand, a conjugate base is what is left over after an acid has donated a proton during a chemical reaction. Hence, a conjugate base is a species formed by the removal of a proton from an acid.

Because some acids are capable of releasing multiple protons, the conjugate base of an acid may itself be acidic.

Represented as the following chemical reaction:

Acid + Base ⇌ Conjugate Base + Conjugate Acid

The water molecule is the conjugate acid of the hydroxide ion after the latter received the hydrogen proton donated by ammonium. On the other hand, ammonia is the conjugate base for the acid ammonium after ammonium has donated a hydrogen ion towards the production of the water molecule. We can also refer to OH- as a conjugate base of H2O, since the water molecule donates a proton towards the production of NH+4 in the reverse reaction, which is the predominating process in nature due to the strength of the base NH3 over the hydroxide ion.

When you work at a call center you will come across irritated, angry, and abusive customers, you can say you will do that following to handle them:

-  Listen to them and empathize with their situation

-  Apologize and take ownership of the problem and give a solution

-  Approach them and ask for a reason for their displeasure

-  If they insist on talking to your manager, get him on line ASAP

- Follow up after giving the solution and ask for feedback
