Q: What type of solid has atoms arranged in a repeating pattern? Read this paragraph and choose the correct option from the provided answers: Some solids are not crystals. Glass, or the rock obsidian, are solid. However, they are not crystals. In a crystal , the atoms are arranged in a pattern. This pattern is regular and it repeats. The image below shows how the atoms are arranged in halite (table salt) ( Figure below ). Halite contains atoms of sodium and chlorine in a pattern. Notice that the pattern goes in all three dimensions. Choices: - ions - metals - hydrocarbons - crystals A:
crystals

Q: Cooling or evaporation of what from the sea surface makes surface water dense? Read this paragraph and choose the correct option from the provided answers: Cooling or evaporation of fresh water from the sea surface makes surface water dense. This causes the surface water to undergo downwelling. Choices: - dirty water - salt water - warm water - fresh water A:
fresh water

Read this paragraph and choose the correct option from the provided answers: Electromagnetic radiation from the sun reaches Earth across space. It strikes everything on Earth's surface, including these volleyball players. Choices: - particle - static - seismic - electromagnetic A:
A: electromagnetic

Q: Which atomic model shows that the distances of electrons from the nucleus is not a fixed value? Read this paragraph and choose the correct option from the provided answers: In the Bohr model, the atom is viewed as a densely packed nucleus comprised of neutrons and protons that is surrounded by electrons at fixed distances, which correspond to specific energy levels. However, the quantum model showed that the distances between electrons and the nucleus are not really fixed. Due to their wave-like nature, we cannot pinpoint the exact location of an electron that is in motion, but we can determine the probability that a given electron will be in a particular region in three-dimensional space. Schrdinger's equations are used to determine the position of a specific electron with respect to a nearby nucleus. The region in space in which an electron is most likely to be found is referred to as an orbital . Choices: - the electron model - the distance model - the equivocation model - the quantum model A:
**Answer**
the quantum model

Q: What is muscle tissue that is attached to the bone called? Read this paragraph and choose the correct option from the provided answers: Muscle tissue that is attached to bone is skeletal muscle . Whether you are blinking your eyes or running a marathon, you are using skeletal muscle. Contractions of skeletal muscle are voluntary, or under conscious control. Skeletal muscle is the most common type of muscle in the human body, so it is described in more detail below. Choices: - ligament - cartilage - epithelial tissue - skeletal tisse A:
(Answer)
skeletal tisse
