All right Quizmaster, this one was less risky. I don't really agree with your definition of a theory but it would be a bit complicated to explain that (and to make a short clue ;) ).

I don't think the first letter of each answer should be given - it's not the kind of quiz that needs it, like quizzes where there could be multiple answers for each question or where the questions have to be vague

Lithium does not mean "third element of the periodic table". It is the third element, but that's not a definition.

Penumbra comes up frequently when talking about eclipses.

Odd that the definition of lithium is:

the chemical element of atomic number 3, a soft silver-white metal. It is the lightest of the alkali metals

of which the first clause is equivalent to the periodic table definition.

It doesnt say anywhere "the first thing".
bostjan

Level 72
Feb 18, 2021
It doesn't say first thing, but an egg becomes a zygote when it is fertilized. The correct answer could have been Earth, if you want to be unfairly pedantic, since that's what every living thing eventually becomes anyway. But that's not how people think correctly. I think that, if the quiz is to be informative, the correct answer should be "zygote," since that is the thing that an egg becomes upon fertilization, by definition, and the given answer of "embryo" is a couple steps after that, if the zygote is successful at surviving, that it.

I got it, but it took me a while. The way the clue was phrased, I was thinking naturally occurring substances. As is, watch out for these substances, they can kill your plants. If it had said a type of poison designed to kill plants, I would have gotten it immediately.

The photosynthesis definition isn't correct. Plants don't convert sunlight into energy, they convert water and carbon dioxide into energy. They do use sunlight to activate this process though.
PearlP

You're right. Plants converts carbon dioxide and water into oxygen and sugars 'in the presence of' sunlight. Sunlight is the energy that drives this chemical reaction. The clue seems to suggest something else.

really dislike the theory definition. theory is more of an explanation of how a phenomenon works supported by experimental evidence.

hypothesis is about making a testable question- often times a hypothesis is written knowing that it is not correct, but is needed to exclude alternate possibilities

A fertilized egg is called a zygote, which then evolves to a blastocyst. It doesn't become an embryo until it implants. So the question would be better asked "what a blastocyst becomes after implantation" or in layman's terms "What does a fertilized become after it implants?"
