What did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

different species on different islands

all species on one of the islands

identical species on all the islands

the same species as North America

What is the advantage of having genetic variation in a population?

To increase changes of survival in a changing environment

To look different from other species.

To be able to change the traits born with to survive an environmental change

To protect itself against predators.

Natural selection is the process by which

organisms with traits well-suited to their environment reproduce at a greater rate than those having less favorable traits in the same environment

change occurs in the genetic characteristics of individuals that live together in an environment from one generation to another

use and disuse of a characteristic leads to evolutionary change

baseball players pass on the trait for strong arm muscles to children

In natural selection, what does the selecting?

genetic makeup of the individual

Antibiotic resistant bacteria are a problem because:

we can't help people with those infections

they are not a problem, I love being sick

What can we do to reduce the rate of development of antibiotic resistant strains of bacteria

Always finish a course of antibiotics

Only take antibiotics when they are really needed

Reduce the amount of antibiotics given to animals in the farming industry

Take antibiotics whenever it is possible

What can happen to bacteria cells when a person takes an antibiotic?

the resistant cells survive and reproduce

the bacteria cells change to become resistant

the cells with unfavorable traits survive

the cells with lower fitness survive

Why was Methicillin introduced as a way to treat Staph infections, according to the graph?

the bacteria became resistant to Penicillin

the bacteria became resistant to Methicillin

Methicillin effectively killed all hospital acquired Staph bacteria

A population of cockroaches was sprayed with an insecticide. Some cockroaches survived and produced a population of cockroaches that was resistant to this spray. What can BEST be inferred from this example?

Individuals with favorable variations survive and reproduce

species will adapt no matter what the environment

environment has no effect on the survival of an organism

Insecticides cause mutations that are passed on to the next generation
