The ______ ________ limits the number of organisms that the ecosystem can support.
carrying capacity
___________ is the formation of a new species.
Speciation
Genetic continuity in sexually reproducing organisms requires _____________ which produces cells with half the number of chromosomes.
Meiosis
How do viruses reproduce?
By infecting a host cell and replicating, using energy from the host.
Why are offspring produced through sexual reproduction genetically different from their parents and each other?
crossing over, genetic recombination, etc.
What are some examples of limiting factors in an ecosystem?

monosaccharide, 1:2:1
If you get a viral infection, should you take antibiotics? why or why not?

What is the difference between exponential growth and logistic growth?
Exponential is a J curve that continues to increase. Logistic is an S curve that levels out at carrying capacity.
What could be a possible explanation for the divergence of bear species into the polar bear and the grizzly bear?
They were separated at some point because their environments changed. the polar bear developed white fur to blend in with snow and the grizzly bear developed dark fur to blend in with its environment.
__________ synthesize proteins and then attach to the ________, a network of membranes that form transport tubes. The _____________ then modifies them and packages them into ___________. These then bind to the __________ for transport out of the cell.
Ribosomes, ER, Golgi, Vesicles, Cell Membrane
What is biological resistance?

DNA, RNA, protein
Why is biodiversity important?
Biodiversity contributes to the resilliance of an ecosystem and allows it to recover after a disturbance.
When comparing the amino acid sequences of 2 organisms, how would you be able to determine how recently they diverged from a common ancestor?
The more similar their amino acid sequences, the more recently they diverged.
