100
The most commonly used species concept.
What is the biological species concept?
100
Viruses that have a protective coating around their nucleocapsid are known as this.
What is enveloped?
100
This domain of cells occured first on earth.
What are archaea?
100
Fungi get their energy from this.
What is food?
100
Archaeans can survive in very harsh and hostile conditions. They are commonly referred to as this.
What are extremophiles?
200
This early species concept emphasizes physical differences to seperate organisms into different species.
What is the morphological species concept?
200
The protein shell of a virus containing many repeating subunits.
What is a capsid?
200
The three domains of life.
What are eukarya, bacteria, and archaea?
200
Give an example of a protist.
Answers vary (ex. malaria, algae, slime mold, T. cruzi)
200
Bacteria have this protective outer layer.
What is a capsule?
300
The form of speciation in which the two species are not geographically seperated.
What is sympatric speciation?
300
This virus shape.
What is helical?
300
This large boom of life occurred at the start of the Paleozoic era.
What is the Cambrian Explosion?
300
These fungi form symbiotic relationships with photosynthetic microorganisms, usually algae.
What is lichen?
300
This bacteria shape
What is cocci/spherical?
400
All of the following are types of reproductive isolation except for
Gametic negation
Behavioral isolation
Hybrid breakdown
Mechanical isolation
What is gametic negation?
400
In this virus life cycle, the virus incorporates its DNA into the host bacteria's chromosome, and the host reproduces normally, duplicating the viral DNA.
What is lysogeny/the lysogenic life cycle?
400
This theory states how the predecessors to eukaryotic cells took in smaller cells that could create energy or food very efficiently. The smaller cells eventually became the mitochondria and chloroplast.
What is endosymbiosis?
400
Fungal cells that have no division of the cytoplasm are know as this.
What is coenocytic?
400
Bacteria do this by connecting to each other and sharing small segments of DNA, known as plasmids.
What is conjugation?
500
Two species of snakes share similar morphology and on rare occasions will interbreed and produce viable offspring. Despite the fcat that they live in the same habitat, this interbreeding is rare because they have vastly differing niches. Under this species concept, they would be considered different species.
What is the ecological species concept?
500
A virus such as AIDS, that replicates many times without killing the host cell, is an example of this kind of animal virus.
What is persistent?
500
An experiment by this scientist in 1953 showed that organic molecules, such as amino acids, can form inorganically, in "early earth" conditions.
Who is Stanley Miller?
500
This phyla of fungi produces large fruiting bodies carrying spores in sacs known as asci.
What is ascomycota?
500
These types of bacteria have thick cell walls made of peptidoglycan, which easily absorbs chemical stains.
What are gram-positive bacteria?
