I believe that the best answer for this question would be spirillum. Spirillum is a genus of bacteria within the family of Spirillaceae. Typically, they are big, elongated, rigid, and spiral-shaped. Some have flagella tufts at either end. They are typically found in still freshwater. Hope this helps.
There would just be dust everywhere. There would be nothing: no stars, galaxies, planets, or life. There would just be nothing.
The correct answer is Mitosis.
The mitosis is a type of cell division, in which the parent cell produces a similar type of daughter cell. The daughter cells, which are formed by the process of the mitosis would have the same number of the chromosomes and the ploidy of the daughter cells would also be same as the parents. In the sexual reproduction, the process of meiosis result in the formation of haploid cells during the process of gamete formation. Hence, meiosis, sexual reproduction, and gamete formation are incorrect answers.
