Single celled Organisms
What does "Eu" in Eukaryote mean?
True
(True or false) An example of natural selection would be frogs that are green survive in the forest longer than red frogs.
True
Where is the major source of you microbiome located?
Stomach/gut
What is it called when two species interact?
Symbiosis
What is the term for a bacterium that can exchange its genes with another nearby bacterium.
Conjugation (lateral gene transfer)
How do Prokaryotes reproduce?
Binary Fission
What is the term for a species that has multiple traits within the same population?
Variation
(True or false) All bacteria are bad
False
A tick getting blood from a dog.
Parasitism
Describe how a mutation effects antibiotic resistance
A gene mutates to help a bacteria have a defense against something that is trying to kill it.
What is the part of a Bacterium that helps with movement called?
Flagellum
What is it called when two species evolve to help eachother live?
Coevolution
Name a way bacteria helps you live.
Digestion, fighting off bad bacteria, aiding in reproductive health
A bird getting nectar from a flower and a flower having its pollen spread.
Mutualism
Explain why species with genetic relatedness might help eachother to cooperate or promote cheating.
Fighting for the same resources would cause cheating, fighting together to get a resource would promote cooperation.
Name an organelle that Prokaryotes and Eukaryotes don't share.
Mitochondria, Helical DNA/spherical DNA, Capsul, NUCLEUS
What are the 4 major parts of natural selection? (this will be a test question)
variation, inheritance, selection and time
(true or false) All bacteria are killed by a prescribed antibiotic.
False
A squirrel living in a tree. (Tree does not care)
Commensalism
Over time, genes in a population change due to species getting specialized traits that help them survive. What is that called?
Adaptations.
How does a disease go from transmittable to "epidemic"
Wide spread transmission. (No clear distinction)
What is the definition of Natural selection? (You must use the words "fit", "survive", and "reproduce")
A species that is fit enough to have the ability to survive long enough to reproduce.
Why is diversity good for your microbiome?
Diversity promotes different kinds of bacteria that all specialize in helping you and other good bacteria live. The more species we have the more bases we cover in internal gut health.
Describe two ways bacteria can spread from human to human.
Liquids (snot and sneezes), and Contact (A firm handshake after those first two...)
Why is it beneficial for humans to have extreme variation within our species?
More chance for survival, less plagues effecting a large population, genetic disorders and diseases will be mitigated and a lot more! (It's all in the next unit...)
