In scientific notation, the radius of each bacterium in a petri dish is 3.15 × 10-7 meter. the radius of the bacterium written as a decimal number in standard form is
meters.

radius of bacterium is given as

r = 3.15 * 10^{-7}m

now we know that

10^{-7} = \frac{1}{10^7} = \frac{1}{1}

now using the above value

r = 3.15 * 10^{-7} m

r = \frac{3.15}{10^7} m

r = \frac{3.15}{1} m

r = 0.315 m

so above is the standard form of the representation.

explanation:

the answer would be 24

hope this !

the answer is 1. photosynthesis. glad to
