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:
Sadly the peafowl are unable to swim, they have four toes on their feet. Three toes face forward and one toe faces backwards. This unique combination of toes enables the peacock to perch easily on branches of trees. They do not have webbed feet which are necessary for birds to actively swim.

Compare:
They are all natural disasters that cause a lot of damage.
Contrast:
Hurricanes are storms that cause high waves and can get into citys and towns and cause a lot of water damage.
Tornadoes are tunnels of wind that cause wind damage.
Blizzards are storms with strong winds and snow that can cause water, and wind damage!
