This sounds a lot like its hinting at the bodies proactiveness in preparing for evolution of any sort.
I would say the 2nd one It helps growth and repair of cells of orgasms
But your school would probably say the 3rd one It helps remove toxins from the body to maintain homeostasis
The answer would be d because the genes come the two parents
To know what happens here, you need to analyze the alleles.
If the father is color blind and the daughter is not, you can suppose that is a recessive allele.
You can tell she is a carrier only, and because we received one sexual allele from each parent. If they ask you about the gender, we can suppose a cross between Xx and XY being lower x the recessive allele (color-blind vision).
When you draw the Punnett square, you'll found the probabilities are XX, XY, Xx, and xY.
So, you have a 50% chance of having a boy and 25% chance of having a color-blind boy.
It should be equal
nothing is lost, nothing is created
