To calculate the water's salinity
by Elena
Well, there are two kinds of organisms: osmoregulators, that can regulate the level of salt and the salinity does not affect them (an example is salmon: for salmon this sentence is true. Generally, for most fish this sentence is true)
However, for some species, such shark - osmoconformers - this is false: they are affected by the salinity. in general I would conclude that This is false: the marine salinity DOES affect the fish (and other organisms) living there.
Correct answer : are eukaryotes
1. They are not plants. Plants belong their own respective kingdom : Plantae, while Mushrooms are in the fungi kingdoms.
2. As the statement states, they are heterotrophic. They do not have the ability to use photosynthesis, as they take nutrients from their surrounding environment.
3. Eukaryotes = Multiple cells. Yes, they are eukaryotes.
4. Prokaryotes are almost always bacteria.
5. Unicellular = one cell
