Really Tough Trivia Stuff Trivia Quiz

Answer: Collagen

Collagen makes up around 25 to 35 percent of the total body protein content. It can be found in bones and cartilages. It is a strong and flexible protein. Keratin can found in human hair and nails. Tubulin regulates intracellular transport. Arginine is an essential amino acid which means our body needs this amino acid from an external source and cannot produce it on its own.

Answer: Copper

Azurite is an ore of copper. It is a blue-colored ore with a chemical formula of Cu3(CO3)2(OH)2. Copper is a brownish-yellow colored metal that is used for various purposes. It is ductile and conductive hence used in making electrical wires. It is also used in making utensils.

Answer: Scissors

In a first class lever system, the fulcrum is located between load and effort. The effort is the force applied by us. The load is the weight on the lever and the fulcrum is the fixed point around which the lever moves independently. Scissor is a first-class lever system. Lemon squeezer and Nutcrackers are second class lever system where the load is located between fulcrum and effort. Tongs come under the third-class lever system where effort is located between load and fulcrum.

Answer: Hydrochloric acid

Hydrochloric acid is also known as muriatic acid. It is also written as HCl. It is a strong acid and has a pungent smell. This acid is also produced in our stomach in small amounts. It aids digestion and helps kill any microorganisms that might have reached there through ingestion.

Answer: False

The Rankine scale is an absolute scale which was proposed by the Scottish Physicist William John Macquorn Rankine in 1859, based on the Fahrenheit scale. The symbol of the Rankine scale is degree Rankine or °R. On this scale, pure water freezes at 492 degrees Rankine and boils at 672 degrees Rankine.

Answer: 0

This was a bit of a trick question. There are no electrons in the nucleus of an atom. The nucleus of an atom has protons and neutrons in it. If an atom has atomic number 6, it means it has 6 protons in the nucleus and 6 electrons revolving around the nucleus. The mass number is 12, which means there are 12-6 = 6 neutrons in the nucleus.

Answer: Hand

The capitate bone can be found in the human hand. It is the largest of all the carpel bones present in our wrist and forms its center.

Answer: White

The purest form of CuSO4, also known as anhydrous copper sulfate is a dry white powder-like substance. Here the word anhydrous represents the lack of water in CuSO4. When mixed in water it gets hydrated and starts giving a blue color. Its hydrated form (which is more common and stable at room temperature) can be written as CuSO4.5H2O.

In its hydrated crystalline form, it is also known as blue vitriol.

Answer: Guard cells

Chloroplasts contain chlorophyll which is required for photosynthesis. Plants need carbon dioxide, water, and sunlight with chlorophyll to do photosynthesis and in return, we get oxygen as a byproduct of this process. Guard cells are the specialized cells that are found in stomata. Stomata are the small pores through which the plant breathes. Companion cells move sugars and amino acids in and out of sieve elements. Tracheids are long cells in the xylem tissue of plants that transport water and minerals.
