Q: What is formed when different gases are confined to the same container? Read this paragraph and choose the correct option from the provided answers: Gases mix homogeneously when confined to same container. When several gases are added to a container, the individual gas particles mix freely, forming a homogeneous mixture in which each type of gas is randomly distributed throughout all the available volume. Choices: - linear mixture - particulate mixture - compact mixture - homogeneous mixture A:
homogeneous mixture

Q: Q: What state of matter exists if particles do not have enough kinetic energy to overcome the force of attraction between them? Read this paragraph and choose the correct option from the provided answers: If particles do not have enough kinetic energy to overcome the force of attraction between them, matter exists as a solid. The particles are packed closely together and held rigidly in place. All they can do is vibrate. This explains why solids have a fixed volume and a fixed shape. Choices: - plasma - liquid - gas - solid A:
A: solid

Question: Q: What do puffer fish produce to protect itself? Read this paragraph and choose the correct option from the provided answers: This odd-looking creature is a fish called a puffer fish. Like all fish, puffer fish are vertebrates. The puffer fish puffs up by rapidly filling its stretchy stomach with water. The reason? Getting bigger makes the fish seem larger to potential predators.

Q: What is the process of moving air into and out of the lungs called? Read this paragraph and choose the correct option from the provided answers: Respiration begins with ventilation, the process of moving air into and out of the lungs. Gas exchange in the lungs takes place in across the thin walls of pulmonary arteries in tiny air sacs called alveoli. Oxygenated blood is transported by the circulatory system from lungs to tissues throughout the body. Gas exchange between blood and body cells occurs across the walls of peripheral capillaries. Choices: - naturalization - hydration - insulation - ventilation A:
**Answer**
ventilation

Q: Q: What's it called when the reaction is sped up until equilibrium is established? Read this paragraph and choose the correct option from the provided answers: If more NH 3 were added, the reverse reaction would be favored. This "favoring" of a reaction means temporarily speeding up the reaction in that direction until equilibrium is reestablished. Recall that once equilibrium is reestablished, the rates of the forward and reverse reactions are again equal. The addition of NH 3 would result in increased formation of the reactants, N 2 and H 2 . Choices: - limiting - pushing - division - favoring A:
A: favoring
