Answer:
DNA replication is described as semi-conservative.
Explanation:
DNA replication is described as semi-conservative because each double helix formed comprises one strand from the helix from which it was copied and a new strand. That is, the replication of one helix results into two new copies of which each contains one of the original double stranded helix from which it was synthesized.

What is different concerning the DNA in bacterial cells as opposed to eukaryotic cells

• Which of these statements is true regarding cell division in the body of a growing teenaged human?
o Only a subset of cells is dividing at this point o We grow by cell division, but not all of our cells are dividing
• Dividing cells must copy their DNA
( replication ), segregate DNA and other cellular components during
( mitosis ) and split apart during
( cytokinesis)
• Our chromosomes exist as many sets of similar pairs with the EXCEPTION of our sex chromosomes o the sex chromosomes of the human female are also pairs. It is the X and Y of the male that break this rule •
A. Carbon dioxide levels are increasing in the air, and the ocean is absorbing carbon dioxide; atmospheric levels are increasing so much that the increase is still apparent even with increasing absorption of carbon dioxide by the ocean. Research conducted by the University of Miami (UM) has found that the waters of the North Atlantic absorbed 50 percent more carbon dioxide of human origin in the last ten years than in the past decade.
The results of the study show the impact that the burning of fossil fuels has had on the world's oceans in the last ten years
