Well, I don't fully understand your question. I think I know what you're getting at though.
In a system of sexual reproduction, you have genes coming from both an egg and the sperm. Therefore, it'll only contain half the total amount of chromosomes (46 in humans). A sperm will have 23, and the egg will have the other 23. Is that what you meant why the chromosomes are cut out in pairs? If that wasn't your question, please elaborate and I'll return to answer it to the best of my capabilities.
Answer:
Degree Heating Week (DHW) shows how much heat stress has accumulated in an area over the past 12 weeks (3 months) by adding up any temperature exceeding the bleaching threshold during that time period.
Answer: Replication is called semiconservative because each of the original strand is is used as a template for the synthesis of a new strand
Explanation: DNA is a double-stranded helix containing two antiparallel strands that are complementary to each other.
Replication is the process of making identical copies of a DNA molecule. Before replication begins, the double-stranded DNA is first unwound by helicase so that each strand will serve as a template for new strand synthesis.
DNA replication is semiconservative because each DNA strand serves as a template for the synthesis of a new strand, producing two new DNA molecules each one with one new strand and one strand.
Saved and used in the new strand
The answer would be fats and proteins.
