Answer:

The correct answer is option A, that is, mitosis only has one cell division set.

Explanation:

The two kinds of nuclear division that takes place at the time of cell differentiation are meiosis and mitosis. In the process of mitosis, the cells of the body get divide, while in meiosis the sex cells are differentiated.  

While going through the process of mitosis, the cell divides only one time, on the other hand, during meiosis a cell divides two times. After going through mitosis production of two diploid daughter cells takes place, while after going through meiosis generation of four haploid daughter cells takes place. Thus, it is clear from the diagram that the process of meiosis is taking place, as the formation of four haploid cells is taking place as the cell is dividing two times.

How does reproduction leads to natural selection in a population
Advocard [28]

Natural selection requires variation between individuals. Mutations and reproduction increase genetic variation in a population. Natural selection occurs when environmental pressures favor certain traits that are passed on to offspring.

What is the pH of 0.10 M NaF(aq). The Ka of HF is 6.8 x 10-4
dsp73

<u>Given information:</u>

Concentration of NaF = 0.10 M

Ka of HF = 6.8*10⁻⁴

<u>To determine:</u>

pH of 0.1 M NaF

<u>Explanation:</u>

NaF (aq) ↔ Na+ (aq) + F-(aq)

[Na+] = [F-] = 0.10 M

F- will then react with water in the solution as follows:

F- + H2O ↔ HF + OH-

Kb = [OH-][HF]/[F-]

Kw/Ka = [OH-][HF]/[F-]

At equilibrium: [OH-]=[HF] = x and [F-] = 0.1 - x

10⁻¹⁴/6.8*10⁻⁴ = x²/0.1-x

x = [OH-] = 1.21*10⁻⁶ M

pOH = -log[OH-] = -log[1.21*10⁻⁶] = 5.92

pH = 14 - pOH = 14-5.92 = 8.08

Ans: (b)

pH of 0.10 M NaF is 8.08
