Answer:
A.producing changes in the genetic code
Explanation:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
The right option is; a. A tree grows tall
A tree grows tall is an example of cell division at work because growth is associated with cell division. Also, cell division in multicellular organisms such as plant involves tissue growth and maintenance. Cell division is a process of reproduction in which a cell divides into two or more cells. In this process, production of new cells involves DNA replication and there are various types of cell division. Prokaryotes (such as bacteria) divide their cell using binary fission, while eukaryotes divide their cell by mitosis or meiosis in some.
<span>The correct answer is testes. Gametes are sex cells, meaning that when the sex cell from a male joins with the sex cell from a female, reproduction occurs. In males, the sex cells are sperm and in females, they are eggs. The formation of these sex cells occurs in the testes for males and in the ovaries for females. So, the second option is incorrect because ovaries belong to females, gametes are incorrect because they are the product of the gamete formation organs, and the last option is incorrect because oogonia is a female sex organ for a specific type of algae. </span>
