You observe an animal-like protist under the microscope. it has no hairlike or whiplike structures. it moves by forming temporary bulges of cytoplasm. how would you classify this protist?

it is a protozoa, specifically an amoeba

Explanation: protozoa is classified under the kingdom protista.

Protozoa consist of microscopic , Unicellular animals .they are said to be the most primitive.protozoa are highly adaptable and are found anywhere.they reproduce asexually by binary fission, multiple fission and budding.some reproduce sexually.Most protozoa are parasitic eg trypanosoma.

they move with the aid of pseudopodia, flagella and cilia.

The amoeba moves by the pseudopodia,by temporarily protruding it's cytoplasm.

Within it's cytoplasm is it's nucleus,contractile vacuole and food vacuole .

It feeds by engulfing food and digesting the food particle in a food vacuole.

Gaseous exchange is by diffusion through it's cytoplasm.

It's contractile vacuole helps it control excess water in it's cytoplasm.amoeba reproduces by binary fission or multiple fission

coal is not sustainable because it will one day run out.

not too sure but maybe in the hot springs.
