distance

Q: What term means the abnormal or excessive extension of a joint - particularly a hinged joint - beyond its normal range of motion, thus resulting in injury? Read this paragraph and choose the correct option from the provided answers: These include anterior-posterior movements of the arm at the shoulder, the forearm at the elbow, the hand at the wrist, and the fingers at the metacarpophalangeal and interphalangeal joints. For the thumb, extension moves the thumb away from the palm of the hand, within the same plane as the palm, while flexion brings the thumb back against the index finger or into the palm. These motions take place at the first carpometacarpal joint. In the lower limb, bringing the thigh forward and upward is flexion at the hip joint, while any posterior-going motion of the thigh is extension. Note that extension of the thigh beyond the anatomical (standing) position is greatly limited by the ligaments that support the hip joint. Knee flexion is the bending of the knee to bring the foot toward the posterior thigh, and extension is the straightening of the knee. Flexion and extension movements are seen at the hinge, condyloid, saddle, and ball-and-socket joints of the limbs (see Figure 9.12a-d). Hyperextension is the abnormal or excessive extension of a joint beyond its normal range of motion, thus resulting in injury. Similarly, hyperflexion is excessive flexion at a joint. Hyperextension injuries are common at hinge joints such as the knee or elbow. In cases of "whiplash" in which the head is suddenly moved backward and then forward, a patient may experience both hyperextension and hyperflexion of the cervical region. Choices: - sprain - tear - hypercorrection - hyperextension A:
hyperextension

Q: Q: What kind of air does a continental polar air mass hold? Read this paragraph and choose the correct option from the provided answers: An air mass takes on the conditions of the area where it forms. For example, a continental polar air mass has cold dry air. A maritime polar air mass has cold moist air. Which air masses have warm moist air? Where do they form?. Choices: - cool moist air - frigid wet air - warm dry air - cold dry air A:
A: cold dry air

Question: Q: Water is an oxide of what element? Read this paragraph and choose the correct option from the provided answers: Carbon dioxide is an oxide of carbon, while water is an oxide of hydrogen. Early scientists viewed oxidation as a process in which a substance was reacted with oxygen to produce one or more oxides. In the previous examples, magnesium and methane are being oxidized. Choices: - nitrogen - helium - carbon - hydrogen A:
Answer: hydrogen

Q: What form when water vapor condenses in the air around specs of matter? Read this paragraph and choose the correct option from the provided answers: Clouds form when water vapor condenses in the air around specs of matter. Clouds are classified on the basis of where and how they form. Types of clouds include cirrus, stratus, and cumulus clouds. Choices: - humidity - storms - condensation - clouds A:
**Answer**
clouds

Q: What factor largely determines the distinguishing features of terrestrial biomes? Read this paragraph and choose the correct option from the provided answers: Terrestrial biomes include all the land areas on Earth where organisms live. The distinguishing features of terrestrial biomes are determined mainly by climate. Terrestrial biomes include tundras, temperate forests and grasslands, chaparral, temperate and tropical deserts, and tropical forests and grasslands. Choices: - density - sea level - migration - climate A:
climate
