Lame (but technically true) nitpick! He clearly means “A (type of) bacteria.” You will find that this “mistake” is quite common and may even be said regularly on the news. It’s not a big deal.

99% percent of quiztakers know what is Andromeda but only 84% percents of them know that Sun is heavier than Earth? Also only 76% knows the pH of water and 66% knows the function of mitochondria. They are very basic knowledges that any middleschool student can easily answer.

Don't forget that the school systems can be widely differ between countries or even states. And from comments under other quizzes I get the impression that for some people here the middle school was long time ago. Do you really remember everything you learned back then?

Good for you that you can remember everything you ever learned in middle school. I wasn't interested in science back then. Most things I know now I looked up myself when that changed. And multiple choice sometimes makes you rethink logical things or things you thought you knew. Yes, our sun is so much bigger than the earth but is it that clear it's heavier? I mean it's mostly made up of gasses which could easily be lighter no matter the enormous size. Just saying.

That was exactly my thinking when I got the earth/sun question wrong. Knowing how vastly greater the sun is only makes me think it could be a "trick" question. :P

That was my initial thought, too, and I obviously got it wrong. I thought it was a trick question. But if you consider how many times Earth would fit in the Sun, then you realise that our reasoning was totally stupid! lol

This is a trivia site, and as such, much of what is quizzed here is "trivial", as in "not much use in everyday life." How often does an average person use info like the pH of water or the purpose of mitochondria or whether the sun is heavier than the earth (I'm honestly surprised even 84% get that right)? No need to be shocked that not everyone knows these things.

You don't actually need to know the pH of water to get that question right – you only need a vague sense of how the pH scale works. And if there is anyone here high school age or over that can't logic out that the sun is heavier than the Earth, I am very sad about the state of basic science knowledge in the world. I agree with you that not everyone will know all these answers because some are indeed "trivial" (I had no idea about the 5,000-year-old tree, for example), but most of these questions had choices that could be figured out with basic knowledge that in my opinion, should. be. known.

Having taught middle schoolers I can definitely say next to none of them would know these facts. Perhaps that says something about the US school system...

level 68
Jun 2, 2019
Having taught both high school and middle school science I would say that trivial knowledge of irrelevant facts are not an indicator of anything. Students who end up in the sciences would know these. Adults who don't work in these fields offload any knowledge that's irrelevant to their current jobs or life. For example, I imagine there is a higher rate of parents getting the chicken pox answer correct than adult non-parents - especially parents who were around before the vaccine. That doesn't make adults smarter than non-parents. It's just trivia.

"any middleschool student can easily answer" This is true, but once you leave middle school you have to retain the knowledge. People forget a lot of things if they don't use the knowledge in their daily lives. I got 100%, but there is plenty of knowledge I have forgotten that I once knew in middle school.

I think I remembered everything besides the mandatory year of history, and the german die,das der, den, die grammar. (also a mandatory subject which I didnt choose). Ow and maybe some artmovement stuff (again mandatory which I dropped). I honestly dont think I remember anything I learned in history class. (Only the stuff I allready knew beforehand) I cant think of anything I learned there now anyway, trying hard to think of something. (I do like history though, but more about civilisations and not about dates of wars and names of generals etc)

@NINJAQKk there's a company in the US called 23 and me, which offers the service to analyse your genetic sequence (the 23 chromosomes) and give you information about your ancestry, predisposition to illnesses etc. Kal just replaced the correct answer to the genome question in the quiz with one of the wrong options.

That question about the moon was so wrong in terms of expression...it should be *natural satellite cause it basically asks what is the largest natural satellite of our solar system
+2
level 57
Jun 2, 2019
A moon is a natural satellite of a planet. All sufficiently large objects in the solar system are natural satellites of something, so the answer if it was changed to natural satellite would be the sun.

Well... Mitochondria is the powerhouse of the cell!
+1
level 57
Jun 2, 2019
Just a few nitpicky comments -
The word "heavy" generally refers to weight and not mass so question one should probably ask which has the higher mass, not which is heavier.
A better answer to question 8 would probably be to conduct aerobic respiration, as energy is not really "generated" per se, it is released from the glucose and oxygen.
An amount of energy is always measured in joules (or some equivalent unit such as electron-volts or kilowatt-hours), so for question 12 the question could be phrased more generally (though it is fine as it is).

Overall a very good quiz though.

"Heavy" is used in this sense commonly, though, even by astrophysicists. It's commonly understood what is meant by it is how heavy something would be given its mass if it were at normal Earth gravity.

Although it's mostly accepted that the earth is 4.5 billion years old, the real answer is no one knows (for sure) because it is unmeasurable. It could be 4.6 or 4.4 billion, for example.

level 57
Jun 2, 2019
This is about how old the Earth is, not the universe. We know how old the Earth is, as QM said above, to a reasonable degree of approximation, and the same is thought to be true of the universe though I recently saw an article saying new evidence suggests that it may be significantly younger (significantly in this context means around 12.5 billion years instead of 13.8 billion years).

The age of the Earth is very debatable. Because carbon dating has been proven to be very faulty, it is not a reliable source to date anything.
+3
level 65
Jun 3, 2019
Carbon dating is only “faulty” if used for the incorrect timescale, of which billions of years is too long. This is why astrophysicists don’t use it to approximate the age of the universe, and instead rely upon cosmic microwave background radiation (CMB), which is for much longer timescales.

Grrr.... I guess so. Sodium is a mineral in the dietary sense. It isn't a mineral in the sense the question was asking. Here's a list of all mineral species. Sodium is absent. In any case, changed the answer to Lithium to avoid further discussion.
