C) stores heredity information
As per the rules of bionomial nomenclature, the species name that is written correctly is C. Pelecinus polytyrator (or B, because you wrote two answers which are completely the same).
You capitalize the genus name, but write the specific epithet in small letters.
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.
The dependent variable is how high the ice cube floats (measured in units).
