Are You Smarter Than a Amoeba? Easy Bio-Trivia! 2

A squid has two long tentacles in addition to its eight arms, while octopuses have only their eight arms.

The flagellates exhibit the greatest diversity of nutrition among the protozoans, some of which are animal-like and others plantlike.

An enzyme acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process.

Louis Pasteur disproved the theory of spontaneous generation (the concept that bacterial life arose spontaneously), a question which at that time divided scientists into two opposing camps. By means of simple and precise experiments, including the filtration of air and the exposure of unfermented liquids to the air of the high Alps, he proved that food decomposes when placed in contact with germs present in the air, which cause its putrefaction, and that it does not undergo transformation or putrefy in such a way as to spontaneously generate new organisms within itself.

The sea cucumber is any of 1,200 species of marine invertebrates of the class Holothuroidea, related to starfish.

Homeostasis is the self-regulating process by which biological systems tend to maintain internal stability while adjusting to changing conditions.

Hibernation is a state of greatly reduced metabolic activity and lowered body temperature adopted by certain mammals as an adaptation to adverse winter conditions. The term hibernation is commonly applied to all types of winter dormancy in vertebrate animals.

The term fungi applies not only to mushrooms but to all of the large and diverse group of plantlike organisms to which the mushrooms belong.

Glycine is the simplest amino acid, obtainable by hydrolysis of proteins. Sweet-tasting, it was among the first amino acids to be isolated from gelatin.

Morphogenesis is the shaping of an organism by embryological processes of differentiation of cells, tissues, and organs and the development of organ systems according to the genetic "blueprint" of the potential organism and in response to environmental conditions.

The American biologist Edward O. Wilson popularized sociobiology, the study of the genetic basis of the social behavior of all animals, including humans. He pioneered sociobiology through his research on ants.

Amino acids are the building blocks of proteins. Although more than 100 amino acids occur naturally, only 20 are commonly used in protein synthesis; these are the same in all living organisms, from protozoans to plants and animals.

Phylogeny is the history of the evolution of a species or group, especially in reference to lines of descent and relationships among broad groups of organisms.

Nettie Maria Stevens, an American biologist and geneticist, was one of the first scientists to find that sex is determined by a particular chromosome. In 1905, after experiments with the Tenebrio molitor beetle, she published a paper in which she announced her finding that the chromosomes known as X and Y were responsible for the determination of the sex of an individual.

Chlorella algae has been studied as a food source because it is rich in proteins.
