Jorge is conducting an comparative experiment where he is comparing the heights of adults who grew up taking a certain vitamin and adults who did not. He finds that those who took vitamins are, on average, 2 cm taller. What is a major limitation of his experiment?

Answers

Answer:

Major limitation of Jorge's experiment are -:

Vast amounts of data can be obtained.He does not prove definitively that a person is taller because of vitamins. No association between vitamins and height can be seen.

Explanation:

ABOUT VITAMINS -:

A vitamin is an organic molecule that is an important micronutrient that an organism requires in limited amounts for the proper functioning of its metabolism (or a chemically closely connected group of molecules, i.e. vitamins). In the body, basic nutrients can not be synthesized in adequate amounts, either at all or not, and must therefore be ingested via a diet.

Hence, the major limitations of the experiment are mentioned above.

Which one is not needed ?

Answers

Answer:

Space

Explanation:

Answer:

Well... I would say it is gravity that is not needed.

Explanation:

In the picture at the top it says "we need to breathe air and live in some type of space. If these requirements are lacking, life ceases to exist."

Thus, stating that air, space, energy, and water are needed for life to exist. That leaves out gravity. Gravity is not needed for life to exist because, for example, humans and other living organisms are already living in outer space without the need for gravity.
