GB2_Quiz 2 (Lesson 2)

It is the process of how present-day organisms have descended from ancient ones.

A well-supported, testable explanation of a natural phenomenon.

A key factor for an organism to thrive and reproduce depends on how well suited the organism is to the environment.

• Stanley Miller

• Harold Urey

• Charles Darwin

• Charles Darwin

• Alexander Ivanovich Oparin

• Harold C. Urey

Which of the following were the best environments for organic reactions to occur during early Earth?

It happens when a change in the environment causes a change in the observable spectrum of phenotypes

• directional selection

• stabilizing selection

• diversifying selection

• disruptive selection

It occurs when intermediate phenotypes are more likely to survive in the environment.

• directional selection

• stabilizing selection

• disruptive selection

• diversifying selection

In populations of animals with multiple male mating strategies, such as lobsters, large alpha males can obtain a mate by force, whereas small males can sneak in to copulate with females in an alpha male's territory. In this situation, both large and small lobsters will be naturally selected, but medium-sized males, which cannot overtake large males and are too big to sneak unlike small males, will not be favored. What type of natural selection exist in this kind of situation

In Artificial Selection, nature provides the variation among different organisms so that humans can select the variations that are useful to them. This can be done through a technique called ____
