A student observes some effects of electricity. The student records these observations in the following table. What should the student record in place of letters P and Q in this table?

• electric current for both P and Q

• static electricity for both P and Q

• electric current for P and the static electricity for Q

• static electricity for P and electric current for Q

How is an electromagnet different from a bar magnet? Select TWO answers.

• An electromagnet has only one pole.

• An electromagnet does not attract iron.

• An electromagnet can be turned on and off.

• An electromagnet is created by electric current.

• An electromagnet does not have a magnetic field.

Which is the BEST comparison of static electricity and electric current?

• Static electricity flows through wires, while electric current jumps across wires

• Static elecctricity involves open circuits, while electric current involves closed circuits

• Static electricity involves the build-up of electrons in an object, while electric current involves the flow of electrons through wires

• Static electricity begins with objects that have a negative charge, while electric current begins with objects that have a positive charge.

Which statement about vertebrates is true?

• Vertebrates have skeletons.

• Vertebrates live only on land.

• Most animals are vertebrates.

• Vertebrates do not have backbones.

• flowering plants, coniferous plants

Which statement describes how deposition builds up the surface of a floodplain?

• Lava flows from a volcano and piles up

• Rainwater seeps into the ground and freezes

• A river flows over its banks and slows down

• A river slows down as it flows into the ocean
