Which of these options was NOT a result of humans beginning to control fire?

The discovery of fire changed the way we're built. We began cooking food on controlled fires around 790,000 years ago— which meant the average human was soon consuming far less dangerous bacteria. Turns out, less raw meat = less grossness. That soon led to shorter human digestive tracts, as there was less of a need to process foods. The increase in healthy meat consumption also led to more energy available, which evolution translated into taller bodies and larger brains.

If a person was thrown into space without a spacesuit, how would they die?

We've all seen the movies: if you're ever thrown out into the vacuum of space, you can basically expect to disintegrate, right? Or your blood will boil, or something. Not true! Turns out, we're made of tougher stuff than Hollywood seems to think. For example, although many liquids do boil in open space, our blood is kept in check by our circulatory system and would therefore be OK. Freezing isn't a concern either, as a vacuum actually acts as a pretty good insulator. It's not all good news though: your death would still be pretty gruesome. The lack of air will render you unconscious in about 15 seconds... before you asphyxiate and die in about a minute.

How long does it take for the brain to react to alcohol consumption?

Pixabay
Advertisement
Brain cells experience a reaction to alcohol consumption within a mere 6 minutes. Alcohol is able to cross the blood-brain barrier, which means it can actually touch brain cells directly. This helped perpetuate the idea that “alcohol kills brain cells,” which is somewhat of a myth anyway: moderate alcohol use doesn't kill brain cells, while rampant abuse can damage the brain.

How much stronger is Earth’s gravity, compared to the Moon?

Shutterstock

If you lived on the moon, you would weigh a lot less than you do now. Gravity on the moon is a mere sixth of the gravity on Earth. This is because the moon has only 1% of the mass of Earth. A human’s weight will vary depending on what planet they are on.
