Front

What do transitional fossils best support?

Back

The Theory of Biological Evolution.

Front

What is the result of increased upwelling in a coastal area?

Back

More aquatic life.

Front

What happens to the deer population if wolves are removed from their area?

Back

The population of deer will increase.

Front

What does the Law of Superposition state?

Back

In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.

Front

Why were some strawberries able to survive a hard freeze?

Back

They have different genetic variations that cause them to be more resistant to cold temperatures.

Front

What is biological evolution?

Back

The process by which species change over time through genetic variation and natural selection.

Front

Define upwelling in oceanography.

Back

The process where deep, cold, nutrient-rich water rises to the surface, supporting marine life.

Front

What is the significance of genetic variation in a population?

Back

It increases the chances of survival and adaptation to changing environments.

Front

Explain the concept of natural selection.

Back

The process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the role of predators in an ecosystem?

Back

Predators help control the population of prey species, maintaining balance in the ecosystem.
