Unsaturated fats have these double bonds which bend the structure. These "kinks" in the molecule are what make unsaturated fats liquid at room temperature.
Gametes are mature haploid cells, or sex cells. When gametes unite with others from the opposite sex in the form of fertilization they create a zygote which then forms an embryo etc. At the end of meiosis the gametes only have <u>half</u> the chromosomes of the organism (only one copy of DNA)
