Q: Answer the following question given this paragraph: The pharyngeal slits are located in the pharynx. The pharynx is the tube that joins the mouth to the digestive and respiratory tracts. Q: Where are the pharyngeal slits located? Choices: - nasal cavity - larynx - esophagus - pharynx A:
A: pharynx

Q: Answer the following question given this paragraph: Why do satellites stay in orbit? Why don't they crash into Earth due to the planet's gravity? Newton's law of universal gravitation describes what happens. Every object in the universe is attracted to every other object. Gravity makes an apple fall to the ground. Gravity also keeps you from floating away into the sky. Gravity holds the Moon in orbit around Earth. It keeps Earth in orbit around the Sun. Q: What keeps earth in orbit around the sun? Choices: - energy - motion - momentum - gravity A:
A: gravity

Q: Answer the following question given this paragraph: Figure below shows how phospholipid molecules are arranged in a cell membrane. One end (the head) of each phospholipid molecule is polar and attracts water. This end is called hydrophilic ("water loving"). The other end (the tail) is nonpolar and repels water. This end is called hydrophobic ("water hating"). The nonpolar tails are on the inside of the membrane. The polar heads are on the outside of the membrane. These differences in polarity allow some molecules to pass through the membrane while keeping others out. You can see how this works in the video at the URL below. Q: The end of the phospholipid molecule that is polar and attracts water is called what? Choices: - cytosolic - hydrophobic - magnetic - hydrophilic A:
A: hydrophilic

Q: Answer the following question given this paragraph: Kinetic and potential energy add up to mechanical energy. Q: Mechanical energy can also usually be expressed as the sum of kinetic energy and what other kind of energy? Choices: - reflective energy - directional energy - partial energy - potential energy A:
A: potential energy
