This is Biology homework. I want to solve those questions based on the materials that I will be uploaded for you. Before solve questions, you should take a look about chapters powerpoint and study guides. There are 4 powerpoint and 4 study guides for chapter 1, 2, 3, and 4. The file name of homework is (Assignments+Chapters+1-4).

Be sure, to write easy words and easy vocabularies. Because I am international student and my English writing is very weak. Also I want to be free plagiarism.
