the science calorie (little c) is a measure of heat energy the food calorie (big C) is a measure of energy that we burn, but it is equal to 1,000 science calories so 1 big C is equal to 1,000 little c's.
Protists are a group made up of protozoa, unicellular algae, and slime molds. We will concentrate on the animal portion of this group: the protozoa (proto = first, zoa = animals).
Animals are multicellular; most protozoans are unicellular.      For protozoans that are multicellular, the organism is built up of  cells that are all the same type â¦ . Animals have cells that have  differentiated and are thus more than one type in the same  organism.ut the ones refered to as this are usually called this because they do not produce their own energy (i.e. Autotrophic...Photosynthesis) but rather active â¦ ly hunt prey to get energy. Which is what animals do, so they are animal-like in that manner.
