evolution remediation

The phrase "survival of the fittest" refers to the -

• fastest organism in a specific environment

• strongest organism in a specific environment

• best-adapted organism in a specific environment

• biggest organism in a specific environment

IS the following an example of mutation or evolution; Physical structure of an organism that is best suited to survive in an environment

• mutation

• adaptation

Is the following an example of mutation or evolution; the survival and reproduction of the individuals who are exhibiting variations that best enable them to survive in their environment

• mutation

• adaptation

Is the following an example of mutation or evolution; changes in the DNA of of an organism

• mutation

• adaptation

Is the following an example of mutation or evolution; a change that can cause a species to go extinct

• mutation

• adaptation

A forest experiences some changes to foliage (leave color). An existing population of beetles have variations in their colors that include orange and green. Based on the evidence in all 3 pictures, what can be said about variations?

• The variations in color decrease the probability of a beetle surviving and reproducing in this changing environment.

• The variations in color increase the probability of a beetle surviving and reproducing in this changing environment.

• The variations in color don't affect the probability of a beetle surviving and reproducing in this changing environment.

• The variations in color help every beetle survive and reproduce in this changing environment.

Look at the genetic variations in the mice family. How is it possible for two parents with gray fur (F) to have offspring with white fur (f)?

• Genetic variation is the result of both dominant and/or recessive genes being passed down.

• Genetic variation is the result of mutations caused by pollutants.

• Genetic variation is the result of an organism's desire to survive and reproduce.

• Genetic variation is the result of the changing environments due to climate change.

What is the relationship between mutations, variations in traits, and natural selection?

• Mutations create variations in a population that don't allow organisms to survive. Therefore, mutations stop organisms from being naturally selected.

• Variations in a population only come from mutations, which will lead to natural selection.

• Mutations create variations in a population. If those variations allow a population to succeed in their specific environment, those individuals are naturally selected for survival.

• Natural selection leads to variations in organisms. Random and spontaneous mutations can stop natural selection from occurring.

The finches (birds) in the Galápagos Islands are similar, but the finch on each island has a different variation of beak. What is the most likely explanation for the different variations of beaks?

• Predators on the island are attracted to birds of different beaks.

• Chemical waste spills in the Pacific Ocean led to mutations in bird beaks.

• C. Large amounts of rainfall on the islands led to the variety in beak sizes.

• The various beaks are each best-adapted to the type of food found on their specific island.

A forest near a river experiences severe flooding more than normal. A species of lizard in one of the affected areas does not have any traits to allow it to survive, nor does it have adaptations for this change in the environment.

What will MOST LIKELY happen to the species if the lizards cannot move to a new habitat?

• It will become extinct.

• It will experience a random mutation in its DNA.

• It will disappear for a short time and repopulate later.

• It will evolve by natural selection to have webbed feet.
