What organelle found in eukaryotic cells was once thought to be bacteria?
The endosymbiont theory posits that multiple cells came together to mutually benefit one another. In this case, the mitochondria was engulfed by a eukaryotic cell leading to the cellular structure observed today.
What is the name of the region of DNA that exists as a buffer on the edge of chromosomes?
Telomeres are buffers on the end of chromosomes that protect against DNA from being permanently damaged by DNA transcription.
What is the term for when similar characteristics emerge across species that are not taxonomically related?
Although bats are not related to insects, the fact that both of these creatures developed a similar physical structure of a wing is an example of convergent evolution.
What is the name of the theory that describes how the mitochondria came to exist within the cell?
Mitochondrias are believed to have previously existed out of eukaryotic cells but now reside within them as they present mutually beneficial outcomes for one another.
The word “biology” derives from a latin root, meaning what?
The term was coined in the 19th Century, coming from both the German and the French word bios, meaning life.
Which term characterizes an organism that eats only plants?
Herbivores are evolutionarily advantaged in their capacity to acquire energy via plants.
What is the process whereby light energy is used to combine carbon dioxide and water, producing oxygen as a byproduct?
Photosynthesis is used by many organisms, primarily plants, that contributes to their metabolism.
Natural Selection posits that fitness is determined by what characteristic of a species?
Survival of a species is postulated to be tied to their reproductive ability.
What was the name of the ship that Charles Darwin sailed on to the Galapagos?
During the 1830s, Darwin sailed on the HMS Beagle as a Naturalist, during which he documented his findings that lead to his theory of Natural Selection.
The eukaryotic cell membrane is composed mostly of what element?
The phospholipid bilayer, mostly made of fats and alcohol, create a barrier for which cells can regulate which types of materials can cross the cell barrier.
Natural Selection posits that fitness is determined by what characteristic of a species?
Survival of a species is postulated to be tied to their reproductive ability.
