specific traits that help the fitness of a species
What is adaptation

What process leads to favoring one variation over another in a species?
What is Natural Selection
200
Which scenario correctly depicts natural selection A - bacteria were exposed to antibacterial drugs. Some mutated their DNA to combat the drug. This change was passed on to offspring which survived the drug. B- bacteria were exposed to antibacterial drugs. The DNA in some randomly mutated. The gene the drug was affective on changed. This change was passed on to offspring which survived the drug.
What is B

In the northern midwest states Wolves have been reinitroduced to the environment. Before the wolves were reintroduced bears and coyotes were the top predators. Would it be beneficial for the 3 animals to compete for the same food sources or find their own niche.
What is find their own niche
400
If 2 organisms mate but produce an offspring that could not have offspring. What does that say about the original parents?
What is they are of a different species.
400
All organisms, trees to bacteria to humans share a common ancestor. The evidence scientists have for this is that all organisms have this one thinig in common.
What is all have DNA

A species of rabbits has many different ear lengths. This is an example of
What is variation
500
A genetic change remains in a species if it _________________ fitness
What is increase or improves
500
True or false - Natural selection works by organisms changing because their environment changes
What is False
500
True or False - In a population of 1,000 fish of the same species, 600 are black, 400 are white. Overtime, the population of black fish went down to 200 the population of white fish went up to 500 and 300 of the fish were a new grey color. This new grey fish is a new species.
What is False...it is just a new variation.
