Question: Answer the following question given this paragraph: Parts of a Typical Rib The posterior end of a typical rib is called the head of the rib (see Figure 7.27). This region articulates primarily with the costal facet located on the body of the same numbered thoracic vertebra and to a lesser degree, with the costal facet located on the body of the next higher vertebra. Lateral to the head is the narrowed neck of the rib. A small bump on the posterior rib surface is the tubercle of the rib, which articulates with the facet located on the transverse process of the same numbered vertebra. The remainder of the rib is the body of the rib (shaft). Just lateral to the tubercle is the angle of the rib, the point at which the rib has its greatest degree of curvature. The angles of the ribs form the most posterior extent of the thoracic cage. In the anatomical position, the angles align with the medial border of the scapula. A shallow costal groove for the passage of blood vessels and a nerve is found along the inferior margin of each rib. Q: The posterior end of a typical rib is called what? A:
OPTIONS:
- neck
- chest
- bottom
- head
Answer: head

input with options: Answer the following question given this paragraph: The warm-air vent is placed near the floor of the room. Warm air is less dense than cold air so it rises. If the warm-air vent were placed near the ceiling instead, how would this affect the transfer of thermal energy throughout the room?. Q: What property of warm air causes it to rise above cold air? A:
OPTIONS:
- greater pressure
- greater density
- higher temperature
- lower density
output: lower density

Q: Answer the following question given this paragraph: Animals are multicellular eukaryotes in the Animal Kingdom. All animals are heterotrophs. They eat other living things because they can't make their own food. All animals also have specialized cells that can do different jobs. Most animals have higher levels of organization as well. They may have specialized tissues, organs, and even organ systems. Having higher levels of organization allows animals to perform many complex functions. For a visual introduction to what makes a living thing an animal, watch this short video: https://www. youtube. com/watch?v=DXPhJUHooP8 . Q: All animals have specialized types of what basic structures, which can then do different jobs? A:

OPTIONS:
- proteins
- muscles
- atoms
- cells

A: cells

input: OPTIONS:
- oxidation
- Diffusion
- permeability
- reactivity Now, answer this question: Answer the following question given this paragraph: Reactivity is the ability of matter to combine chemically with other substances. For example, iron is highly reactive with oxygen. When it combines with oxygen, it forms the reddish powder called rust (see Figure below ). Rust is not iron but an entirely different substance that consists of both iron and oxygen. Q: What term describes the ability of matter to combine chemically with other substances? A:
A:
output: reactivity

Question: Answer the following question given this paragraph: When a sarcomere shortens, some regions shorten whereas others stay the same length. A sarcomere is defined as the distance between two consecutive Z discs or Z lines; when a muscle contracts, the distance between the Z discs is reduced. The H zonethe central region of the A zonecontains only thick filaments and is shortened during contraction. The I band contains only thin filaments and also shortens. The A band does not shortenit remains the same lengthbut A bands of different sarcomeres move closer together during contraction, eventually disappearing. Thin filaments are pulled by the thick filaments toward the center of the sarcomere until the Z discs approach the thick filaments. The zone of overlap, in which thin filaments and thick filaments occupy the same area, increases as the thin filaments move inward. Q: The distance between two consecutive z discs or z lines is called what? A:
OPTIONS:
- contractile
- ligule
- radius
- sarcomere
Answer:
sarcomere
