It is B
Explanation:
I had this question on my test last week
It is definently All of the above because all of them have been advancements over the years
<span>Genes -- and, thus, the traits they code for -- are passed from parent to offspring. From generation to generation, well-understood molecular mechanisms reshuffle, duplicate, and alter genes in a way that produces genetic variation. This variation is the raw material for evolution.</span>
<u>Answer:</u>
Angle of inclination is the independent variable.
Distance covered by the rolling ball is the dependent variable.
<u>Explanation:</u>
An independent variable is the one whose variation is not dependent on the value of any other variable while dependent variable changes its value with a change in the independent variable.
In this experiment, angle of inclination (angle between a line and the x-axis) is an independent variable whereas the the distance covered by the rolling ball is a dependent variable which will vary with a change in angle of inclination.
