DNA replicates before cell division, duplicating chromosomes. This occurs during S stage of interphase! Now each chromosome has two identical double helical models.
Explanation:
the lower power will focus betterthan the high magnification
Photosynthesis<span> makes the glucose that is used in </span>cellular respiration<span> to make ATP. The glucose is then turned back </span>into <span>carbon dioxide, which is used in </span>photosynthesis<span>. While water is broken down to form oxygen </span>during photosynthesis, in cellular respiration<span> oxygen is combined </span>with<span> hydrogen to form water.

Cold air is drier because the water molecules are more likely to condense to a liquid.
This was the answer on my course, hope it helps!
Nucleic acid<span> typically contain phosphorous, and nitrogen plays an important structural role in nucleic acids and proteins. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium.</span>
