In the diagram of the human digestive system, what organ is labelled 5?
il63 [147K]

Answer:

The large intestine

Explanation:

The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.

As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the <em>small intestine</em>. Since we know that the large intestine <em>wraps around</em> the small intestine, we can infer that the organ is the large intestine.

Hopefully that was helpful! :)

A student wants to test the hypothesis that plants need soil to grow. Identify the independent
bija089 [108]

Answer:

Independent variable: Adding/not adding soil.

Dependent variables: Does the plant grow? Amount of leaves, plant length.

Controlled variables: Type of plant used, amount of sunlight received, pot used for plant, amount of water given, temperature of soil, etc.

Explanation:

Independent variable: The thing that you want to change. To see if plants need soil to grow, you would need to either add or remove soil altogether.

Dependent variables: The thing that is being measured. By adding your independent variable, you should be able to answer certain questions.

Controlled variables: Things you want to keep the same for each experimental group. For example, if you used different plants, your results could be affected negatively as some plants might rely on soil less than others/grow at a slower or faster pace.
