I Love Biology Trivia Quiz

Answer: Anton van Leeuwenhoek

Anton van Leeuwenhoek observed bacteria as well as discovering sperm and determining that it was a source of reproduction. The fact that he did this in the late 1600s makes him a man ahead of his time.

Answer: Drosophila melanogaster

The correct answer was Drosophila melanogaster. The fruit fly has been the subject of many scientific studies. Daubenonia madagascariensis is an aye-aye, Partulina perdix is a land snail and Pyxidea mouhotii is a keeled box turtle.

Answer: Jan Ingenhousz

Jan Ingenhousz was a 18th century Dutch scientist and physician. He discovered that plants go through a process called photosynthesis. Photosynthesis is when a plant converts light energy to chemical energy and stores it in bonds of sugar. He also realized the differences in plant metabolism during night and day.

Answer: Nerve Impulses

Nails on a chalk board, squealing brakes, or a crying baby are all sounds that can make one's skin crawl. When we detect a sound, sound waves travel to our ears and the sound energy is converted to nerve impulses. These impulses travel to the auditory cortex of the brain's temporal lobes for processing.

Another brain structure, the amygdala, heightens our perception of the sound and associates it with a particular emotion, such as fear or unpleasantness.

Answer: Julius Von Sachs

Julius Von Sachs discovered chloroplasts in plants in 1865. He was a founder of experimental plant physiology. 1865 was a good year for science, as Gregor Mendel also introduced his work in the field of heredity.

Answer: False

Cerumen is the proper name for earwax and is only found in your ears. Its reason for existence is protection and lubrication. The common types of gallstones are cholesterol, black pigment, and brown pigment.

Answer: Myth

The 5-second rule is based on the theory that food that has been dropped on the floor for a brief period of time does not pick up many germs and is safe to eat. This is a myth. Several factors play a role in the level of contamination that may occur once food has been dropped on the floor or other surface.

These factors include the texture of the food (soft, sticky, etc.) and the type of surface (tile, carpet, etc.) involved. The level of contamination may vary, but any food is likely to have been contaminated if dropped.

Answer: Anthocyanin

Anthocyanin is a blue, violet, or red flavonoid pigment found in plants.

Answer: Eukaryotic and prokaryotic

Eukaryotic and prokaryotic cells are the two main types of cells. Eukaryotic cells are called so because they have a true nucleus that is enclosed within a membrane. Animals, plants, fungi, and protists are examples of organisms that contain eukaryotic cells. Prokaryotic organisms include bacteria and archaeans.

Answer: Gums

Pyorrhoea, or periodontal disease, to give it a proper medical term, is a disease of the gums and is one of the most widely prevalent diseases. It affects the membrane surrounding the roots of the teeth and leads to loosening of the teeth, pus formation, and shrinkage of the gum. This disease is the primary cause for tooth loss among adults.
