Q: What did rockets help launch into space during their beginning? Read this paragraph and choose the correct option from the provided answers: One of the first uses of rockets in space was to launch satellites. A satellite is an object that orbits a larger object. An orbit is a circular or elliptical path around an object. Natural objects in orbit are called natural satellites. The Moon is a natural satellite. Human-made objects in orbit are called artificial satellites. Choices: - rovers - shuttles - sensors - satellites A:
**Answer**
satellites

Q: In a ketone, two of which kind of groups are attached to the carbonyl carbon atom? Read this paragraph and choose the correct option from the provided answers: Note The carbonyl group is ubiquitous in biological compounds. It is found in carbohydrates, fats, proteins, nucleic acids, hormones, and vitaminsorganic compounds critical to living systems. In a ketone, two carbon groups are attached to the carbonyl carbon atom. The following general formulas, in which R represents an alkyl group and Ar stands for an aryl group, represent ketones. Choices: - ions - nitrogen groups - oxygen groups - carbon groups A:
**Answer**
carbon groups

Q: When magma cools slowly, what texture does it have? Read this paragraph and choose the correct option from the provided answers: Texture indicates how the magma cooled. Magma that cools rapidly has small or no visible crystals. Magma that cools slowly has large crystals; reference the Table above for the type of rock, the amount of silica it has, and examples. Choices: - large squares - large gases - small circles - large crystals A:
**Answer**
large crystals

Q: In the human ear, sound waves cause the stapes to press against what? Read this paragraph and choose the correct option from the provided answers: Figure 36.14 In the human ear, sound waves cause the stapes to press against the oval window. Vibrations travel up the fluid-filled interior of the cochlea. The basilar membrane that lines the cochlea gets continuously thinner toward the apex of the cochlea. Different thicknesses of membrane vibrate in response to different frequencies of sound. Sound waves then exit through the round window. In the cross section of the cochlea (top right figure), note that in addition to the upper canal and lower canal, the cochlea also has a middle canal. The organ of Corti (bottom image) is the site of sound transduction. Movement of stereocilia on hair cells results in an action potential that travels along the auditory nerve. Choices: - yellow window - shaped window - Idea Window - oval window A:
**Answer**
oval window
