The right answer is A.
Meiosis is an important process in many organisms:
In angiosperms, plants with flowers, meiosis occurs for the production of cells of pollen grains (gametes, haploid cells).
In animals, meiosis is important because it is the mechanism of gametogenesis that produces eggs (oogenesis) and sperm (spermatogenesis).
In the fungi, meiosis produces spores, which by mitosis will give a haploid generation.
Cell division is when a cell under goes mitosis. Which divides in top to create another cell of the same kind.
In Gamete a haploid germ of either sex unites with the opposite sex to have sex and have a zygote.
Pieces of genes can be inserted into the genetic material of prokaryotes so that they will make the protein products encoded in the genes or copies of the genes themselves
Chemical change is a process where a current substance changes or is made into a new type of substance<span>. Unlike the physical change, which is reversible. Chemical change stays into a its new form. Take for instance these -physical change- examples, making ice cubes. The process involves solidification or freezing where the water becomes ice or solid but when it melts back to its original or typical form with respect to temperature, it’s still water. When the paper is cut into pieces it isn’t burned or exposed to a stimuli that can trigger immediate change in its composition. It’s still the same. On the contrary, baking a cake involves these different compositions or substances –flour, egg, yeast and etc. that is baked to a cake, a newly formed unified substance of all the included ingredients. </span>
