2. Biologists find water bears in a sample of water collected from Calaveras River. Water
bears are microscopic creatures of size 4.8 nano meters or 4.8*10^-9 meters. Scientists
also found cyanobacteria in the water which are 3.6 micro meters or 0.0000036 meters.
a. How can you represent a cyanobacteria in scientific notation?
b. Which one is larger? How do you know?
c. If the two micro organisms were found side by side, how long would they be
together (write your answer in scientific notation).
d.
How many water bears could stand on top of each other to equal a cyanobacteria
(assuming they would do that - write your answer in scientific notation).
