The EPA is an independent agency formed for environmental protection. Hence the statement The Clean Air Act would be a reason for the Environmental Protection Agency (EPA) to regulate car emissions is true.
Car emissions are very harmful for all the living organisms in an environment.
To accomplish the dilution the microbiologist should dilute 1 mL of the bacterial culture in 100 mL of the total volume. Thus, option C is correct.
<h3>What is dilution?</h3>
Dilution is a process of decreasing the solute concentration by the addition of the solvent in the solution. The volume for the dilution is calculated as:
Given,
C1 = 100,000 cell per mL
C2 = 1000 cell per mL
V1 = 1 mL
C1 V1 = C2 V2
100,000 × (1 ÷ 1000)
= 100 mL
Therefore, 100 mL should be used to dilute 1 mL.

#SPJ1
Nitrogenous base pairs would form the rungs of the ladder.
Answer: 26.75 meters.
2πr = 84
2 * 3.14 * radius = 84
radius = 84/6.28
r= 13.375
So the diameter will be 13.375 + 13.375 which is 26.75 meters.
