II and III only. The fungus is a heterotroph, since it's not making it's own food, but it's also a Saprotroph (since it externally digests dead organic materials; saprotrophs are a special subset of heterotrophs).
<span>Metalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, colored or colorless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides.</span>
Answer:
They sleep on just one side of their brain at a time
Explanation:
Dolphins are different from fishes that can breathe underwater.
It is necessary for them to get to the surface of the water at intervals to breathe air.
While sleeping, dolphins allows one hemisphere of their brains fall asleep while the other half is fully conscious. This means that If the left brain is sleeping, the right eye stays open and if the right brain is sleeping, the left eye stays open.
This happens so they always know when it's time to surface and breathe and when to escape when there is trouble.
