Explanation:
I think it all of the above
The time it takes in milliseconds for the brain to transmit a signal to your skeletal muscles can be determined given the speed and distance. It was given that the signal travels at approximately 25 m/s while the distance between the brain and one' hand can be set to approximately 1 m. To obtain the time, we divide the distance by the speed and convert it to milliseconds.
The equation would be: (1 m/ 25 m/s)*(1000 ms/1 s) = 40 ms.
Thus, it will take 40 ms for the brain's signal to travel before it can command your skeletal muscles to react accordingly.
Haloplanktons from the statement above are one of the two main sub types of zooplankton which, unlike meroplankton, are permanent members of the zooplankton family
<h3>What are holoplanktons? </h3>
Holoplanktons can be defined as organisms which live in the water column and cannot swim against a current for their entire life cycle.
Holoplanktons are one of the two major types of zooplankton that spend their entire lives as part of the plankton. Some examples of these have are:
Therefore, holoplanktons are permanent members of the zooplankton family

Lets understand the experimental setup by breaking down the method.
A group of (I) middle school students were given a short course in speed-reading. The instructor was curious if a (II) monetary incentive would influence performance on a reading test taken at the end of the course. Half the students were offered $5 for obtaining a certain level of performance on the test, the (III) other half were not offered money.
(I) The number of middle school students present will be the constant of the experiment as it is not changing.
(II) Monetary incentive would influence performance on a reading test. This statement reflects that monetary incentive of $5 is the independent variable and the performance on a reading test is the dependent variable.
(III) The other half were not offered money. This statement mentions the control group of the experiment who are not receiving money regardless of their performance in the test. The comparison of the case with incentive of $5 to the control group will help establish any causal effect.
Based on the above understanding of the passage, here's the answer,
1 - (d), 2 - (a), 3 - (b), 4 - (c)
