1. Know the hierarchy of life in order of the individual to the biosphere and what each level consists of. | |
What two domains contain the prokaryotes? | |
Know some general characteristics of each of the groups of microorganisms,example,if a patient were diagnosed with a diseased caused by a single-celled microorganism with a nucleus and moved by means of a flagella, | |
4. With respect to nitrogen-fixation what is a legume, the root nodule, Rhizobium, leg-hemoglobin, and the nitrogen fixers in aquatic environments? Of course, what is nitrogen fixation? | |
5. What are trophic levels and the characteristics of each level?So, for example, how would you answer this question?A cow’s herbivorous diet indicates that it is a(n): | primary consumer |
