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.
Answer and explanation;
-There are advantages to being multicellular rather than unicellular. These include; allowing the organism to be larger, allowing
cell differentiation (having different types of cells with different functions)
, and also allowing the organisms to be more complex.
-Complex organisms often have specialized cells that carry out different functions. Having specialized cells and systems allows the process such as transport of nutrients and waste to and from all the cells of the body to occur.
