Answer: d. both a and b.

Explanation:

Soaps are cleansing agents. These are composed of salts and fatty acids. The soaps functions as degerming agents and surfactants.

A surfactant is a molecule which consists of a lipophilic end which basically attracts the grease and dirt. The other end is the hydrophilic which makes the dirt and grease molecules dissolve in water. This way functions as important cleansing agent.

Answer:

The correct answer will be the cell is in prophase I of meiosis and will enter metaphase I next.

Explanation:

Meiosis is a type of cell division which is involved in the formation of haploid gametes.

During meiosis the division of the genetic material is markedly observed and based on this meiosis is divided into 4 phases: prophase, metaphase, anaphase and telophase.

During prophase: the chromatin structure of DNA starts condensing to form chromatids which attaches to homologous chromatids and are known as sister chromatids. These sister chromatids exchange their genetic material via a process called called recombination or crossing over which takes place during pachytene stage of prophase I. After crossing over it is proceeded by the next stage that is metaphase I in which chromosomes gets aligned at the center of the cell.

Thus, the cell is in prophase I of meiosis and will enter metaphase I next is the correct answer.
