Answer:
c) the emotional or neutral word list
Explanation:
In research, we usually have two different types of variables:
- The independent variable is the one that the researchers can control and that will have an effect on another variable.
- The dependent variable is the one that cannot be control and that is affected by the independent variable. Researchers observe this variable to see how it changes. This is the variable that will be tested or measured.
In other words, the independent variable has an effect on another one and it can actually be controlled by researchers.
In this example, Dr. Kang wants to examine the effects of emotion on memory. In other words, how emotions affect memory. He proceeds to hand a list of words with very emotional content to a group of subjects and a list of neutral words to another group and then measures how many words each group is able to remember. We can see that he thinks emotional words will have an EFFECT on emotion. Also, he can control this variable by handing different lists (emotional or neutral words) to each group. Therefore, this is the independent variable. ( c. the emotional or neutral word list)

D. The mule that results from this mating, is sterile and not able to produce offspring of its own.
Explanation:
Mules are result of the mating between a male donkey and a female horse (a mare). Donkeys have 62 chromosomes, and horses have 64. Mules have a mixture of that - 63 chromosomes. That is what prevents the chromosomes from pairing up. As a consequence, mules end up not being able to create embryos properly, which makes them sterile.
