The correct answer is A. Amount of sleep

Explanation:

In research, there are two main types of variables the dependent and the independent variable. The dependent variable refers to the factor or situation that is being studied by the research and therefore cannot be controlled by it. On the other hand, an independent variable is a variable the researcher modifies or controls in order to understand or study the dependent variable. This means while the dependent variable is the one that cannot be controlled and whose results answer the question of the research the independent variable is the factor control by the research and that varies according to the groups the researcher is studying.

Considering this, if the researcher wants to know the effects of sleep on memory and for doing this it gives two different groups of subjects the same lists to memorize, but different time to sleep the dependent variable is the memory and the list as it is the same for all the subjects and the independent variable, in this case, is the amount of sleep as this is the factor controlled by the researcher.

Write about a time when you successfully kept a News Year's resolution- or write about why you don't make New Year's resolutions
a_sh-v [17]

Why I Don't Make New Year's Resolutions:

The thing about New Year's resolutions is that it's similar to saying "I'll do it tomorrow". Some people say "hopefully next year I lose weight and exercise", see it sounds like a nice goal, but half the time it's just a method to push doing it farther back. It's not supposed to be a deadline that you extend and I get tired of seeing people do that because that means they won't do it here and now.

If you want to get something done, do it now. Not tomorrow, not the day after, and definitely not next year. If you have the time to dream to do this next year, then why can't you do it now? (This applies to the people that truly have time to make these improvements and meet these goals.)

Sorry if this isn't the best, but I hope this helps.
