Answer the following question given this paragraph: A related process to diffusion is the effusion. Effusion is the process of a confined gas escaping through a tiny hole in its container. Effusion can be observed by the fact that a helium-filled balloon will stop floating and sink to the floor after a day or so. This is because the helium gas effuses through tiny pores in the balloon. Both diffusion and effusion are related to the speed at which various gas molecules move. Gases that have a lower molar mass effuse and diffuse at a faster rate than gases that have a higher molar mass. Q: Both diffusion and effusion are related to the speed at which what objects move? Choices: - electricity - copper molecules - solids - gas molecules A:
gas molecules
Answer the following question given this paragraph: Genes play an important role in determining an organism's traits. However, for many traits, phenotype is influenced by the environment as well. For example, skin color is controlled by genes but also influenced by exposure to sunlight. You can see the effect of sunlight on skin in Figure below . Q: Skin color is controlled by genes but also influenced by exposure to what? Choices: - food - precipitation - makeup - sunlight A:
sunlight

Q: What type of bacteria stains red? Choices: - gram - such bacteria - kilogram-negative bacteria - calcium - negative bacteria - gram-negative bacteria A:
A: gram-negative bacteria
Question: Answer the following question given this paragraph: The larynx , also called the "voice box," is found just below the pharynx. Your voice comes from your larynx. Air from the lungs passes across thin tissues in the larynx and produces sound. Q: What is another term for the voice box? Choices: - pharynx - pancreas - optical nerve - larynx A:
Answer: larynx

(Q).
Answer the following question given this paragraph: At the beginning of the reaction, only the reactants A and B are present. Recall that over the course of a reaction, the reaction rate slows down. This is because the rate depends on the concentrations of one or more reactants. As the reactants are used up, their concentrations drop, thus decreasing the reaction rate. Q: What happens to the reaction rate over the course of a reaction? Choices: - reverses - stays the same - speeds up - slows down A:
(A).
slows down
