The genome of a newly-isolated member of the Proteobacteria has been completely sequenced and its genome size determined to be 5.5 Megabase pairs. A broth culture of this Proteobacteria has been grown to a density of 2 x 108 cells per mL in a 5-mL volume. Estimate the total amount of DNA in the culture, express your answer in kilometers, then describe this total DNA length in terms of a symbol on the log scale below (yellow star, black heart, green square, etc.) You may assume that there is exactly one copy of the genome per cell and that each base pair contributes 0.34 nm to the genome length.

Refer to this portion of a dichotomous key for fish identification to answer the question. 1. (a) has a single dorsal fin ® 5 (b) has a double dorsal fin ® 2 2. (a) one fin is spiny, the other is smooth ® 3 (b) one fin is not spiny or smooth ® 4 5. (a) has small fin on back near tail ® 6 (b) has no fin on back near tail ® 7 6. (a) has barbs near the mouth ® catfish (b) does not have barbs near the mouth ® 10 7. (a) tail is asymmetrical ® 8 (b) tail is symmetrical ® 9 10. (a) scales are small ® trout (b) scales are large ® whitefish what is the next step to complete to identify a fish that has a single dorsal fin, no fin on the back near the tail, and no barbs near the mouth? step 2 step 5 step 7 step 10
