BILD 2 Lecture Notes - Lecture 7: Asexual Reproduction, Sexual Reproduction, Internal Fertilization
Document Summary
It turns out that your mitochondria sometimes makes reactive oxidant free radicals" that cause mutations in dna, and antioxidants like vitamin e neutralize these free radicals. Would you expect vitamin e to help with cancer: no, on the one hand, it gets rid of potential mutation-causing radicals. However, these radicals are important for cell death, which could be necessary for cells that should die but haven"t done so yet: must look at complex picture to reach conclusion in biology. Reproduction: generation of new individuals from existing ones. Asexual vs. sexual reproduction: ex: the desert grassland whiptail lizard is an all-female species. When they stimulate mating with each other, one lizard ovulates (produces an egg). The egg doubles its chromosomes and grows into an embryo. Is this asexual or sexual reproduction: asexual: gametes aren"t fused. Sex and reproduction in people: male reproductive anatomy, female reproductive anatomy.
