Why does the cell duplicate its chromosomes before dividing? a. to become a polyploid cell. b. to create genetically different daughter cells. c. so each daughter cell will receive a duplicate set of dna. d. so each daughter cell will receive a full set of dna

The cell duplicates its chromosomes before dividing D. So each daughter cell will receive a full set of DNA.

If the cell were to divide without duplicating its chromosomes, the daughter cells would only receive half of the genetic information from their parents, and thus wouldn't be able to function correctly with only half of a genome. Additionally, you can confirm that the answer is D because the other answers are incorrect. If a cell duplicates before dividing, it will not become polyploid, this occurs with incorrect division, therefore answer A is incorrect. Answer B doesn't fit the question because not all daughter cells are genetically different from their parent cells (mitosis requires duplication but creates identical offspring). Finally, Answer C is incorrect because each daughter cell doesn't receive a duplicate set of DNA in mitosis, the parent cell physically splits itself into two (two daughter cells are created in place of the parent cell).

Hope this helps!

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
