NGSS 8th Grade Review

Front

What is camouflage?

Back

Camouflage is a survival adaptation that allows an organism to blend in with its surroundings, making it less visible to predators.

Front

How do environmental factors influence natural selection?

Back

Environmental factors determine which traits are advantageous for survival and reproduction, affecting the likelihood of those traits being passed on to future generations.

Front

Why do some traits become more common in a population over time?

Back

Some traits become more common because they provide benefits for survival and reproduction, leading to natural selection.

Front

What causes a solar eclipse?

Back

A solar eclipse occurs when the Moon passes between the Sun and the Earth, blocking the Sun's light.

Front

What factors contribute to an animal's chances of survival?

Back

An animal's chances of survival can be influenced by genetic variations, environmental factors, and predator-prey relationships.

Front

What is natural selection?

Back

Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the gradual evolution of species.

Front

Define genetic variation.

Back

Genetic variation refers to the differences in DNA among individuals within a population, which can lead to different traits.

Front

What role do mutations play in evolution?

Back

Mutations are changes in DNA that can create new traits; some mutations may be beneficial and contribute to evolution.

Front

Explain the concept of adaptation.

Back

Adaptation is a trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What is the significance of the predator-prey relationship?

Back

The predator-prey relationship is significant because it influences population dynamics and natural selection, as predators affect the survival of prey species.
