Calorie is the unit. Specific Heat is the actual name for the energy to raise 1 degree.

The question explicitly states "water." This is the definition of a (small c) calorie. The calories can measure specific heat, among other things. There is nothing wrong with this question, even if you take a very pedantic perspective.

it says an animal, not the characteristic, that being said, this is a 5 year later response.

Should be "atom or compound that has an electrical charge." Atoms and charged polyatomic compounds can be ions, but molecules can not.

Strictly speaking, an "atom" has no charge. You might try "atomic particle"

An atom does have a charge, if it's an ion. If an atom has the same number of electrons as it does protons, then it has no (net) charge. However, if it gains one or more electrons, then the atom gets a negative charge. If it loses one or more electrons, then it gets a positive charge. Either way, we call the resulting charged atom an ion.

Were I somehow magically whisked back in time, I realized how utterly hopeless I would be at explaining our modern day knowledge.

"We've got this amazing thing known as electricity that powers our world, turns night into day, propels us at speeds you can't imagine..."

"Amazing! Tell us how it works!"

"Uh, actually I don't know. Get me a kite and key. I'm sure I can figure this out. Anyone know if it's supposed to rain this week?"

I am compelled to be pedantic with the question about catalysts. They increase the rate of a chemical reaction but crucially are not consumed in the reaction. There are many things that speed up reactions but only a catalyst isn't also used up

good quiz, my only whinge is I tried 'omnivorous' several times, I feel it should be counted.

I'm late to respond, but the question is "An animal that..." which requires a noun as the answer. "Omnivore" is a noun. "Omnivorous" is an adjective.

The wording of the question requires a noun for an answer. Omnivorous is an adjective, therefore it is incorrect. Omnivore(s) is a noun, therefore it is the only correct answer.
