1. Describe two roles that prokaryotes have in the environment. What would happen to other organisms if prokaryotes did not recycle nutrients? 2. Describe two ways in which bacteria cause disease. Give an example for each.

 Describe two roles that prokaryotes have in the environment. What would happen to other organisms if prokaryotes did not recycle nutrients?  decomposing waste and dead organisms so that nutrients can be recycled, producers of food and biomass, fixing nitrogen gas so that plants can use it. If prokaryotes did not recycle nutrients, the nutrients would remain in dead organisms and could not be reused by other organisms. Eventually, these organisms would most likely die

 Describe two ways in which bacteria cause disease. Give an example for each.  Bacteria cause disease by damaging cells and tissues and by releasing chemicals that disrupt homeostasis. An example of the former is tuberculosis: the bacteria that cause tuberculosis cause an immune response that breaks down lung tissue. For the latter, the bacteria that cause botulism, a type of food poisoning, release toxins in the body.

 Be prepared to share your response to the following: ◦ Biological evolution happens at the __________ level, not the individual organism level. ◦ All three definitions mention genetic changes or changes in allele frequency within a population from one generation to the next. ◦ Based on what you have learned about evolution and genetics in the past, list 2 or 3 events or circumstances that could cause these changes.

Steps: 1. Remove the excess paper from the top and bottom by cutting along the dotted lines shown below in red.

2. Fold along the center line shown in red below.

3. Cut along the dotted lines between each box. Stop cutting where the dotted lines end.

4. Fold along the red dotted lines shown below so that each box folds open.

5. Glue the section highlighted in yellow below to the back page so that only the tabs will fold open.
