Science Park Trivia Quiz

Answer: Knot

Loop fingerprints are ovular in appearance, and 60-65% of fingerprints are loop shaped. On the other hand, whorl fingerprints are circular in appearance; 30-35% of fingerprints are whorls. Arch fingerprints look like the contour lines surrounding a river, where they curve quickly up and down. They constitute 5% of fingerprints.

Answer: 0.05-3% Salt

The three incorrect answers refer to other possible salinities of water. Water that is less than 0.05% salt is considered freshwater. Water that is 3-5% salt is considered saline. Water that is more than 5% salt is considered brine.
All four of the world's oceans are considered saline. The Pacific, Indian, and Atlantic oceans are of approximately equal salinity, while the Arctic Ocean is less salty, but still considered saline.

Answer: Blue-green

A major difference between cyanobacteria and other types of algae is that cyanobacteria is prokaryotic and most types of algae are eukaryotic. Prokaryotes lack double-membrane organelles, such as ribosomes of a nucleus. They consist of all types of bacteria. Eukaryotes have double-membrane organelles. All forms of life, other than bacteria, are eukaryotes.

Answer: The digestive system is having muscle contractions

In order to move food along the digestive system, the digestive organs have to contract, and this is known as peristalsis. During peristalsis, air bubbles that move with the digested food are squeezed, making a sound. Peristalsis can happen on an empty or full stomach, but the results are louder on an empty stomach.

Answer: Cellulose

Cellulose is composed of a long chain of glucose molecules. It is the primary component of plant cell walls. Despite not being digestible by most humans, Japanese people can digest cellulose. This is due to their long history of eating seaweed, which has allowed them to collect digestive enzymes from the seaweed they've eaten. These digestive enzymes later became part of their genome.

Answer: A fully circular, upside-down loop

If a roller coaster were to have a circular, upside-down loop, there would be enough g-forces generated to be able to snap your neck. In order to counteract this, roller coaster manufacturers either use an ovular loop shape or use a corkscrew with a circular loop to counteract g-forces. 90 degree inclines, 90 degree declines, and speeds exceeding 100 miles per hour are all common in modern roller coasters.

Answer: Ear

The semicircular canals are filled with a motion-sensor-containing fluid which detects even the slightest of movements and helps with balance. There are three different semicircular canals: the posterior, the superior, and the horizontal canal. These canals are connected to the utricle, which senses the movement of your head.

The utricle is connected to the cochlea, which enables you to hear by sending signals to the brain.

Answer: Glucose

A disaccharide is formed when two molecules of monosaccharides are connected together. Lactose is formed from one molecule of glucose and one molecule of galactose; maltose is formed from two molecules of glucose; sucrose is formed from glucose and fructose. Sucrose is commonly known as table sugar, and is the most common sugar that we humans eat. Dairy products are rich in lactose; starchy foods are high in maltose; fruits and vegetables, such as celery, beets, and cherries, are rich in galactose.

Answer: Sirius

The brightness of stars is measured by apparent magnitude, with lower numbers meaning higher visibility. Sirius is the only star with an apparent magnitude of less than -1, and thus is the brightest star in the night sky by far. The sun, however, is much brighter, since it is much closer to Earth. Other planets, by virtue of their proximity to Earth, are also brighter than Sirius.

Answer: 38,700

Each hour contains 3,600 seconds. 10 hours would contain 36,000 seconds, and the extra 3/4 hour created by the 45 minutes would add 2,700 seconds to your total, bringing your total to 38,700 seconds. The ancient Egyptians can be thanked for creating the idea of hours. al-Biruni of Persia can be thanked for inventing many other measurements of time, such as minutes and seconds.
