Q: The sun's gravity is relatively strong because the force of gravity between two objects is directly proportional to their what? Read this paragraph and choose the correct option from the provided answers: As you can see in this NASA photo, Earth is tiny compared with the massive sun. The sun's gravity is relatively strong because the force of gravity between two objects is directly proportional to their masses. Gravity between the sun and Earth pulls Earth toward the sun, but Earth never falls into the sun. Instead, it constantly revolves around the sun, making one complete revolution every 365 days. Choices: - tissues - Liquids - rocks - masses A:
masses

Q: How many different kinds of ions are produced when sodium chloride dissociates ? Read this paragraph and choose the correct option from the provided answers: The sodium chloride dissociates into two ions, while the glucose does not dissociate. Therefore, equal concentrations of each solution will result in twice as many dissolved particles in the case of the sodium chloride. The vapor pressure of the sodium chloride solution will be lowered twice the amount as the glucose solution. Choices: - five - one - three - two A:
two

Q: Dietary proteins are broken down into what components when food is digested? Read this paragraph and choose the correct option from the provided answers: Proteins in the diet are necessary for life. Dietary proteins are broken down into their component amino acids when food is digested. Cells can then use the components to build new proteins. Humans are able to synthesize all but nine of the twenty common amino acids. These nine amino acids, called essential amino acids , must be consumed in foods. Like dietary carbohydrates and lipids, dietary proteins can also be broken down to provide cells with energy. The amino acids regarded as essential for humans are phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, leucine, lysine, and histidine. Additionally, cysteine, tyrosine and arginine are required by infants and growing children. Choices: - organic acids - protein acids - polymer acids - amino acids A:
amino acids

Q: Mineral crystals that form when magma cools are usually _______ than crystals that form when lava cools. Read this paragraph and choose the correct option from the provided answers: Mineral crystals that form when magma cools are usually larger than crystals that form when lava cools. Choices: - older - denser - smaller - larger A:
larger
