Jami is doing an experiment to find out how temperature slows down or speeds up the sprouting of bean seeds. to prepare for the experiment, she plans to put soil into three foam cups and place six seeds in each cup. when jami performs the experiment, which of the following should she keep the same for all of the cups of beans? i. the amount of sunlight ii. the amount of water iii. the temperature iv. the amount of fertilizer a. i, ii, and iv only b. i and iii only c. i and ii only d. ii and iii only

the answer is A because When performing an experiment, it is important to change only one independent variable at a time.

In[?] this experiment, since Jami wants to see how different temperatures [?]affect sprouting, she must change the temperature, but she should leave the amount of sunlight, water, and fertilizer the same for all of the cups of beans.

If[?] Jami changes two variables—such as temperature and water—at the same [?]time and then finds that some of the beans sprouted faster than others, [?]she will not know which change caused the sprouting to speed up.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
