Salt relates to hydrophilic because salt is very attracted to water. Hydrophilic molecules have an affinity for water. They are capable of interacting with water through hydrogen bonding.

The moss on this rock is an example of a bryophyte, a plant that does not flower or contain vascular tissue for the transfer of water and other nutrients throughout the plant. Bryophytes reproduce using spores, not seeds, unlike other flowering plants do.

That is olive oil that is  from the pantry. It is hydrophobic because oils do not bond well with water; if you've ever mixed olive oil and water, the oil and water separate and the oil floats to the top. Hydrophobic means that a substance does not dissolve in water.

Eubacteria: mostly unicellular and does not have a nucleus. Eubacteria can be good when found in food and when breaking down food in our bodies, but they are bad if they are pathogens (in this case causing things such as tuberculosis or typhoid). This particular type of bacteria is found in food such as the cheese in this picture.
