Yuliya22 [10]

Answer:

1. gravel of the sand: a part is dissolved and the remainder is grouped at the bottom of the beaker.

2. drop of sunflower oil: It is not absorbed and heaps on the surface of the water contained in the beaker.

Explanation:

Gravel of the sand is a polar substance. This means that this substance has the ability to dissolve and mix with water in a system in which both were placed together, such as a beaker, for example. However, the beaker limits the amount of water, which limits its ability to dissolve polar substances. Therefore, depending on the quantity, the gravel of the sand, when placed in a beaker with water, will dissolve, in parts, what is not dissolved will accumulate in the bottom of the beacker, because the gravel of the sand is denser than the water.

With the drop of sunflower oil the exact opposite happens. This is because drops of oil are nonpolar substances, which means that they do not have the ability to be dissolved in water. This means that when dropped into the beaker with water, the drop of sunflower oil will not dissolve, but will pile up on the water surface, because it is less dense than water.

4. Living things are sometimes called "carbon-based life forms." Do you think this is a good way to describe life? Explain your
victus00 [196]

Answer:

Explanation:

Yes, for a couple of reasons.

1. Carbon connects easily with other carbons.

2. Carbon forms chemical that can change and connect with other carbons even in biology or especially in Biology. If you take a brown seen and plant it where it can get water and soil nutrients, to will come up as a green plant. Think about the chemistry that goes into that. Not only that, but there are mechanisms that tell the upper part of the plant that the roots can't supply any more growth. Isn't that something? All made from Carbon.

3. The human body is a mass of Carbon based chemicals and all cells there can have different functions. Amazing isn't it? I'm a fan of the diversity of our planet and its growth.
