Please prepare all three essays. Compare your answers with classmates. I will choose one of these to place on the test and you will have to write it fresh for 30 points.
1: Discuss how the concept of horizontal gene transfer relates to bacteria. Include the following in your discussion:
*
bacterial mechanisms of horizontal gene transfer and how they differ from normal inheritance
*
the importance of horizontal gene transfer to the treatment of bacterial infections
*
the effects this concept has on evolutionary relationships inside and outside the bacterial domain
2: Explain why the kingdom Protista is no longer a valid kingdom. Include the following as evidence:
*
the concept of monophyletic vs. para or polyphyletic
*
the evidence that neither protista nor the old subgroups “algae” and “protozoa” are monophyletic
*
your personal suggestion for how the major protist groups could be rearranged to create monophyletic kingdoms (remember to include the higher eukaryotes in your analysis)
3: Compare and contrast reproduction in nonvascular, seedless vascular, and seeded plants. Include the following in your answer:
*
the concept of alternation of generations and how this differs from human reproduction
*
a description of this alternation in moss, including the concepts of sporophyte/gametophyte, diploid/haploid, spore/gamete, and dominant/dependent
*
the key differences between your description in moss and the same processes in seedless vascular and seeded plants
I need a page for each question on the attached handout. Very precise .
