480630 biology expert need for 10 questions

i need a assignment done about 2 pages of my book ill send you the pages of my book details are below ,

Order description : a paragraph answer to each of the following questions. Part 1 1. Explain the importance of sexual reproduction, not only in terms of continuation of the species, but in evolutionary terms as well. Compare the different types of life cycles exemplified by Chlamydomonas, corn (maize), and humans. Be sure to indicate which stage(s) is (are) dominant in each life cycle. How do these life cycles illustrate genetic trends in the evolution of higher plants and animals? 2. Why are calico cats almost always female? In what rare circumstances is a male calico cat possible? Explain the details of the cellular mechanisms that result in their patchwork coat color. In your explanation, be sure to define the following terms: X-inactivation, dosage compensation, Barr body and the Lyon hypothesis. Part2 1. Discuss the three different types of gene mutations discussed in the commentary: Week 6–Gene Mutations and DNA Repair. Describe in detail how addition, deletion, and base substitution of nucleotides can have a significant impact on genes. Find three specific examples (actual gene mutations, not chromosome mutations) of ways in which a very small change in DNA can have a major impact on an organism, and describe each mutation in detail. 2. Why do agricultural researchers intentionally produce polyploid crop plants? Explain in detail what polyploidy means and discuss different types of polyploid plants. Give four specific detailed examples of actual commercial crops that are polyploid. In each case explain why polyploidy is advantageous. Also, indicate whether the polyploidy occurred naturally or describe how botanists created the new varieties. Why is it more common for polyploidy to occur in plants than in animals? Give examples of types of animals that have been found to exhibit polyploidy. Part 3 1. Re-read pages 183-186 in the textbook describing Avery, MacLeod and McCarty\'s important experiment. In your own words, write a few paragraphs that could serve as an abstract for their landmark paper. (Review the procedures for devising an abstract in the \"Scientific Method\" commentary in Module 1.) Abstracts may be quite different in different journals or for different purposes, such as poster presentations. What I am looking for here is a brief summary of the research, including details about how the experiment was carried out. 2. Discuss different models for DNA replication that were considered by early researchers. Explain why they settled on the current model for DNA replication. Describe this model in detail and interpret the significance of helicases, gyrases, RNA primer, DNA polymerase, Okazaki fragments, and DNA ligase. Payout 20.00 US must be doen within the next 8 hours
