SCIENCE TRIVIA VI

51) Which of the following has the LEAST amount of chromosomes?


In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Water buffalo and potatoes each have 48, and Silkworms have 54.

52) How long does it take an individual blood cell to make a complete circuit of the body?


The average person has about 5 liters of blood, and the average heart pumps about 70 ml of blood with each beat. If your heart rate is 70 beats per minute, you will pump about 4.9 liters of blood (70 beats X 70 ml) in one minute, which is roughly your entire blood supply. So an individual blood cell should make a complete circuit of the body at least once every 60 seconds.

53) How many earthquakes are there worldwide each year?


Several million earthquakes occur in the each year across the planet, although many go undetected because they hit remote areas or have very small magnitudes.

54) How fast can lava flow?


Once a lava flows became established and good channels develop, the lava in the channels can flow at up to 60 km/hour. That's faster than a sprinting greyhound!

55) How often do your taste buds regenerate?


The taste buds themselves are a collection of cells on the surface of the tongue, each housing about 50 taste cells. The buds renew themselves every ten days to two weeks. However, anything that causes inflammation, such as infections or smoking, can damage the taste buds and affect their renewal.

56) Who invented dynamite?


Alfred Nobel, a Swedish chemist, invented dynamite in 1867. Nobel held 355 different patents, dynamite being the most famous. After reading a premature obituary which condemned him for profiting from the sales of arms, he bequeathed his fortune to institute the Nobel Prizes.

57) When will the sun run out of fuel?


The sun has used up about half of its hydrogen fuel in the last 4.6 billion years, since its birth. It still has enough hydrogen to last about another 5 billion years before it runs out of fuel and turns into a Red Giant.

58) How much skin will the average person shed during their lifetime?


Humans shed about 600,000 particles of skin every hour -- about 1.5 pounds a year. By the age of 70, an average person will have shed more than 100 pounds of skin.

59) CH3COOH is the chemical formula for what common household item?


Vinegar is approximately 5% acetic acid in water. The structural formula for acetic acid is CH3COOH.

60) Mycology is the study of what?


Mycology is the branch of biology concerned with the study of fungi, including their genetic and biochemical properties, their taxonomy and their use to humans as a source for tinder, medicine, food, and entheogens, as well as their dangers, such as poisoning or infection.
