Hard science quiz 14 questions
A science quiz that’s genuinely hard and you’re not supposed to nail it, but the payoff is learning a whole stack of facts you’ll randomly drop later. Most abundant protein in the human body? Collagen. Hormone that raises blood glucose when it gets too low? Glucagon, not insulin. Mass of a single protein molecule is measured in Daltons, the SI unit of magnetic flux is the Weber, and an animal most active at dawn and dusk is crepuscular. Different versions of the same gene are alleles, helicase unwinds the DNA double helix during replication, and programmed cell death is apoptosis. Telomeres protect chromosome ends, the Golgi apparatus modifies and packages proteins, and lysosomes break down waste with digestive enzymes. RNA carries uracil instead of thymine, the mitral valve separates the left atrium from the left ventricle, and dendrites are the part of a neuron that receives signals from other nerve cells. 14 questions that humble you then build you back up with answers that stick

This is a hard science quiz. You're not expected to know the answer to these questions and don't worry if you get most of them wrong. But have a go, see if you can get any right and worst case scenario, you'll learn a load of new information. What is the most abundant protein in the human body? Collagen. What is the main hormone that raises blood glucose when it becomes too low? The common mistake is insulin. The correct answer is glucagon. What unit is used to measure the mass of a single protein molecule? Dalton What is the SI unit of magnetic flux? The Weber What term describes an animal that is most active at dawn and dusk? Crepuscular What are different versions of the same gene called? Alleles. Which enzyme unwinds the DNA double helix during replication Helicase or helicase What is the name of programmed cell death Apoptosis. What structures at the end of chromosomes help protect DNA from deterioration? Telomeres Which organelle modifies and packages proteins before they are transported elsewhere in a cell? Golgi apparatus Which organelle contains digestive enzymes which break down waste materials within a cell? Lysosome Which nitrogenous base is found in RNA but not DNA? Uracil. Which valve separates the left atrium from the left ventricle? The mitral valve. Which part of the neuron receives signals from other nerve cells? The dendrite.
