Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

Answer:

At the beginning you start out with a lot of energy and stamina but as you progress, maybe five minutes in, you start to get out of breath. While breathing harder, you are trying to intake more oxygen and at the 10 minute mark you can feel your muscles burning a little bit and tire out more. At this point you are gasping for oxygen because your muscles are deprived of oxygen and you body makes lactic acids which you muscles can use instead of oxygen. By the end of it you are very tired.

sesenic [268]

Answer:

A. 50, 88, 145, 227

Explanation:

The correct option would be option A.

<u>When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.</u>

<em>In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.</em>
