Answer:
The dependent variable - the cholesterol level
Independent variables are the exercise and the drug.
Explanation:
A variable is a factor that can be modified or change. It is the factor that can be measured, altered, controlled in research or the experiment. It can be dependent or independent of their effect.
The independent variable is the factor of the experiment that controlled or manipulated by the researcher and it is considered to have a direct effect on the dependent variable whereas the dependent variable is being checked or tested.
So, in this experiment, the variable that is being tested is the cholesterol level that means it is a dependent variable. The independent variable here is exercise and drug as they manipulate and have an effect on the direct variable.
Thus, the correct answer is -
The dependent variable -the cholesterol level and
independent variables - exercise and the drug.
Chest pains and trouble breathing
I had to ask for help on this one. I had no idea what it meant. The people on the forum figured it out (I think). They said it was a driving question and I should have known. I live in the country. We have plenty of both.
Y intersection looks just like a Y. You are coming from the bottom of the Y and moving upwards. You come to a fork in the road and you must choose to go upwards either by taking the left or right hand side. Both will permit you to go in the same direction you were traveling in the first place. You might wind up in a slightly different place.
T intersection. A t Intersection makes you stop because you cannot keep going in the direction you were traveling in the first place. That direction is a complete Dead End.
You are forced to go either left or right at the intersection. The original direction you were travelling is now lost to you. If you were travelling North then the T requires you to go either East or West.
If they have missed the question, let me know. I can edit it.
