- why do the embryos of different species resemble each other?Why is there a need for mitosis and meiosis? Are there characteristics that make them redundant? Explain. If you created an organism, would you use mitosis or meiosis in reproduction? Why? Provide two examples in nature of organisms that only use one process.Humans produce skin cells by mitosis and gametes by meiosis. Which of the following statements about the nuclei of skin cells is correct? a. They contain half as much DNA as the nuclei of gametes produced by meiosis. b. They contain four times as much DNA as the nuclei of gametes produced by meiosis. c. They contain the same amount of DNA as the nuclei of gametes produced by meiosis. d. They contain twice as much DNA as the nuclei of gametes produced by meiosis.
- How is it that the embryo sacs of some apomictic species look normal but contain diploid cells?What embryological evidences support the theory of evolution?What is one statement that would support the theory that all organisms are related? A) The genetic code is almost universal.B) All flies have 2 wings.C) Eukaryotes have mitochondria.D) Prokaryotes have circular chromosomes.E) That the Theory of Pangenesis has held up to scrutiny for thousands of years What is the difference between cross and self-fertilization? A. In cross-fertilization the gametes from one plant are used to fertilize the gametes of another plantB. In cross-fertilization the gametes from one plant are used to fertilize the gametes from the same plant C. In self-fertilization the gametes from one plant are used to fertilize the gametes from another plantD.
