1. Which question could best be investigated using scientific inquiry?

• When do most people plant flower gardens?

• Which color of flowers do people like to grow in their gardens?

• How many flowering plants have become extinct throughout Earth’s history?

• How does the amount of sunlight received affect the growth of flowering plants?

• an organism exchanging materials with its environment

• an organism responding to internal stimuli

• an adaptation helping an organism to survive

• metabolism regulating an organism’s activities

Which statement describes the energy of a ball after it is thrown straight up into the air?

• When the ball is about to hit the ground, its kinetic energy is lowest

• When the ball is about to hit the ground, its potential energy is highest

• When the ball is at its highest point, its kinetic energy is equal to its potential energy

• When the ball is at its highest point, its potential energy is highest and its kinetic energy is lowest .

The diagram below represents the rock cycle.

According to this diagram, metamorphic rock is formed by

• melting and solidification

• burial and compaction

• weathering and erosion

• heat and/or pressure
