How does natural selection contribute to the process of evolution?

• Natural selection allows for the adaptation of species to their environment, leading to changes in the genetic makeup of a population over generations.

• Natural selection always leads to the extinction of species

• Natural selection only affects individual organisms, not populations

• Natural selection is a random process with no impact on evolution

Explain how the study of the rock cycle can help us understand the history of the Earth.

• The study of the rock cycle has no relevance to understanding the Earth's history

• Understanding the rock cycle helps us interpret the history of the moon

• By understanding the processes of rock formation and transformation, we can interpret the Earth's history through the rock record.

• By studying the rock cycle, we can predict future geological events

Keesha performed a chemical reaction and the products looked quite different from the reactants. She knew the amount of matter had not changed due to the law of conservation of mass. According to the law of conservation of mass, what happens in a chemical reaction?

• Matter is not created or destroyed and the same amount of mass remains.

• A new kind of matter is created and the amount of mass either increases or decreases.

• Matter is not created or destroyed and the amount of mass may change after the reaction.

• New matter is created and changes form so that the mass of the reactants and the products will almost be equal.
