Does respiration always involve the production of carbon dioxide and water?
no.
How does the fertilization affect the menstrual cycle?
Fertilization would be when conception occurs, if the fertilized egg implants itself in the uterus lining this is when pregnancy occurs and thus the menstrual cycles stop. Although fertilization doesn't always result in pregnancy, and pregnancy can miscarry at any point.
What kind of gametes can be made of AABbCCDd?
Each gamete contains one allele from each of the genes (in this case one version of each letter). Any gene for which the individual is homozygous (has two of the same alleles) can only produce gametes with that allele. So in this case the organism has BB and dd - so will always have a B and d in the gamete. So the possible gametes are: ABCdE ABcdE ABCde ABcde aBCdE aBcdE aBcde aBCde
What is the result if mutations occur during meiosis?
The offspring of the organism will have a mutation.

What are the different types of sex cells?
The human gametes are the sperm cell (male) and the egg cell (female). The chromosomes carried by the sperm cell can have two forms, the X cell (female offspring) or the Y cell (male offspring). These combine with the egg cell, which virtually always carries only an X chromosome. So an XX cell would develop as a female, and an XY cell would result in a male offspring.

Why genetic variation is still possible if self pollination occurs?
This is because during meiosis there is (mostly) genetic variation by means of crossing over, independent assortment and mutations. As two gametes are being fused, the end product will be different from the parent, because the factors mentioned above ensure this. For a bit more info: The end product might not always be different as sometimes (in a very rare case), independent assortment and mutations might not occur to the two gametes which are to be fertilised, and if the two gametes both contained chromosomes on which crossing over did not occur, and if these two gametes were to fertilise, then the product would be genetically the same as the parent plant.
Does respiration always involve the production of carbon dioxide and water?
