What is speciation?

Back

Speciation is the evolutionary process by which populations evolve to become distinct species. It often occurs when populations are isolated from each other and undergo different evolutionary pressures.

Front

What environmental factor most strongly affects the bill width in finches?

Back

The type of seeds present in their environment is the most significant factor affecting the bill width in finches, as it influences their feeding habits and survival.

Front

What is the function of polar heads in a phospholipid bilayer?

Back

The polar heads help to prevent the fatty acids from sticking together, allowing for fluidity in the cell membrane.

Front

How do evolution and natural selection relate to each other?

Back

Natural selection is a major mechanism by which evolution occurs, as it favors individuals with traits that are better suited to their environment.

Front

Why are individuals more likely to survive in their environment according to natural selection?

Back

Individuals are more likely to survive because they are better adapted to their environment than others.

Front

Define natural selection.

Back

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring.

Front

What is the role of genetic variation in evolution?

Back

Genetic variation provides the raw material for natural selection, allowing populations to adapt to changing environments.

Front

What is an example of a factor that can lead to speciation?

Back

Geographic isolation, such as a river or mountain range separating populations, can lead to speciation by preventing interbreeding.

Front

What is the significance of adaptation in evolution?

Back

Adaptation is significant in evolution as it enhances an organism's ability to survive and reproduce in its environment.

Front

What is the difference between mutation and natural selection?

Back

Mutation is a change in the DNA sequence that can introduce new traits, while natural selection is the process that favors the survival of those traits that are advantageous.
