Answer:
B
Explanation:
A zygote is the resulting cell from fertilization.
Fertilization occurs when the sperm (the male gamete/sex cell) fuses with the egg (the female gamete/sex cell). After they fuse, or fertilize, a cell forms that contains half of the DNA from the father (sperm) and the other half from the mother (egg). It has a complete set of DNA, and is considered a haploid cell.
It is not the structure that nourishes the fetus, an un-fertilized egg, or a ball of about 100 cells. Therefore, the correct answer is B: a sperm fused with an egg.
In Biology, a zygote simply refers to: B. a sperm fused with an egg.
What is a zygote?
A zygote can be defined as an eukaryotic cell that is typically formed by the fusion of two (2) haploid gametes in living organisms, which includes a sperm and an egg.
This ultimately implies that, a zygote is a sperm that is fused with an egg.
Additionally, the female reproductive system is primarily responsible for nourishing a developing zygote within the uterus in humans.
