• Procedure 1: All the reactants were liquids that evaporated.

  Procedure 2: A gas was formed as one product, and it escaped into the air.

• Procedure 1: One of the reactants was converted to thermal energy. Procedure 2: All the products were liquids.

• Procedure 1: The reactants were liquids with different densities. Procedure 2: The reactants were combined into only one product.

• Procedure 1: One of the products was a gas that escaped into the air. Procedure 2: A gas from the air reacted with one of the other reactants.

Some areas of an ocean are known as dead zones. These zones form when excess organic material decomposes. This increased decomposition uses up the oxygen from the water. Which human activity is most affected by the increasing number of dead zones in the ocean?

• Offshore oil drilling, because water in dead zones is toxic

• Commercial fishing, because fish cannot survive without oxygen

• Commercial shipping, because dead zones change the course of ocean currents

• Sand mining, because oxygen is not available to form the sands on ocean beaches

Whitetip reef sharks spend most of the day lying on the ocean floor. While remaining still, these sharks pump water across their gills.

The movement of water across their gills is necessary for —

• staying cool

• accessing food

• obtaining oxygen

• avoiding predators

Many processes occur in the digestive system. Which process is best classified as a physical change?

• Digestive enzymes breaking down proteins into smaller fragments

• Bacteria converting lactose into simple sugars in the intestines

• Teeth grinding an almond into smaller pieces in the mouth

_________ is an objects tendency to resist changes in motion (ex. speeding up, slowing down, stopping)

• Force

• Inertia

• Friction

• Newton
