Where are diploid cells found? A. Only in reproductive organs

B. Only in twins siblings

C. Throughout the body

D. Only in the lungs

diploid cells are found throughout our body, cuz every cell is diploid in our body except the gametes , diploid means cell having full number of chromosomes like 23 pair in human beings.

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
