I think it’s the third option but I’m not entirely sure
The experimental control is the standard used as a comparison for the experimental groups.
For example, you may be trying to find out how different types of disinfectants affect bacterial growth. The control group would receive <em>no</em> disinfectant whereas the experimental groups would be the ones on which the disinfectants were tested.
Hope this makes sense!
Answer: 0.52 L of 15 M 
will be used to prepare this amount of 0.52 M base.
Explanation:
But on diluting the number of moles remain same and thus we can use molarity equation.
(to be prepared)
where,
=concentration of stock solution = 15 M
= volume of stock solution = ?
= concentration of solution to be prepared = 0.52 M
= volume of solution to be prepared = 15 L
Thus 0.52 L of 15 M will be used to prepare this amount of 0.52 M base
Answer:
D. 60.3 kilometers per hour
Explanation:
Hello,
In this case, we first compute the miles in kilometres:
Then the minutes in hours:
Finally, the velocity:
Thus, answer is D. 60.3 kilometers per hour
Best regards.
There are three main stages to a ticks life cycle:tick larva, tick Nymph, and adult ticks. Nymphal ticks cause the most Lyme disease infections in people. They are extremely small and have a painless bite which make them incredibly hard to detect. I hope i helped good luck mate!
