Science GMAS Review 1

What evidence indicates a chemical change has occurred?

• Color change, temperature change, gas production, or the formation of a precipitate.

• Change in mass, change in volume, change in shape, or change in density.

• Change in color, change in size, change in texture, or change in smell.

• Change in temperature, change in pressure, change in state, or change in phase.

What are the characteristics of vertebrates?

• Vertebrates have a skeleton made of bone or cartilage, a nervous system, and are classified into five main groups.

• Vertebrates are exclusively aquatic animals with gills and fins.

• Vertebrates are characterized by their ability to fly and have feathers.

• Vertebrates are cold-blooded animals that lay eggs in water.

What happens to a river as it flows into the ocean?

• The river speeds up and carries more water.

• The river slows down, leading to deposition of sediments.

• The river evaporates completely before reaching the ocean.

• The river changes its color to blue.

What are the two main groups of plants based on reproduction?

• Spore producers and seed producers

• Flowering plants and non-flowering plants

• Herbaceous plants and woody plants

• Aquatic plants and terrestrial plants

What is the backbone's function in vertebrates?

• Provides structural support and protects the spinal cord

• Produces red blood cells

• Stores calcium and phosphorus

• Regulates body temperature

What are vertebrates?

• Animals that have a backbone or spinal column, including mammals, birds, reptiles, amphibians, and fish.

• Animals that live in water and have gills.

• Animals that are warm-blooded and give live birth.

• Animals that are cold-blooded and lay eggs.

How can you increase the strength of an electromagnet?

• By increasing the electric current flowing through the wire.

• By using a thicker wire only.

• By reducing the number of coils in the wire.

• By using a weaker power source.

What is deposition in geology?

• The process of eroding rocks and soil from a landform.

• The process by which sediments, soil, and rocks are added to a landform or land mass.

• The process of transforming liquid rock into solid rock.

• The process of weathering that breaks down rocks into smaller pieces.

What is the role of a river in building up a floodplain?

• A river builds up a floodplain by overflowing its banks and depositing sediments as it slows down.

• A river erodes the floodplain by cutting through the soil and rock.

• A river prevents flooding by maintaining a steady flow of water.

• A river creates a floodplain by diverting water into nearby lakes.

What is a chemical change?

• A process where substances combine or break apart to form new substances, often accompanied by energy changes.

• A physical change that alters the appearance of a substance without changing its composition.

• A reaction that only involves the physical state of a substance, such as melting or freezing.

• A change that occurs when a substance is dissolved in a solvent, resulting in a homogeneous mixture.
