Why do the cells used for reproduction only have half (½) of the DNA that other cells have?
Answer:
Because each chromosome has a pair, these cells are called "diploid" cells. On the other hand, human sperm and egg cells have only 23 chromosomes, or half the chromosomes of a diploid cell.

Hooters of 2 g of sugar in 500 g of water what was the mass of a solution formed formed
Will do the brainlest
Answer:
Explanation:
The answer would be 502 grams because of the law of conservation of mass, you can't create or destroy mass so then 2 grams plus 500 grams is 502.
Answer:1,000 grams
502 grams
500 grams
498 grams
Explanation: The answer would be 502 grams because of the law of conservation of mass, you can't create or destroy mass so then 2 grams plus 500 grams is 502. I am 100% positive that B is correct.
How does DNA copy itself
Explanation:
DNA unwraps itself before cell division. It helps that each side of the double helix is in opposite direction of the other. Then the DNA polymerase travels around each strand and binds the complementary nucleotides (DNA's building blocks). The process is called DNA replication.
