A and C are true statements about a zygote.
A. They form when male sex cells unite with female sex cells. This is true. A zygote is formed when a sperm cell from the father fertilizes an egg cell from the mother.
B. They form when bees pollinate a plant. This statement is false. Bees pollinate plants, but they do not form zygotes.
C. They have a combination of the DNA of both parent cells. This is true. When a sperm cell and an egg cell unite, they each contribute half of the genetic information that will make up the zygote's DNA.
D. Their DNA is an exact replica of the male sex cell. This statement is false. The zygote's DNA is a combination of genetic material from both the sperm and the egg, so it is not an exact replica of either.
