Answer the following question given this paragraph: An articulation is any place at which two bones are joined. The humerus is the largest and longest bone of the upper limb and the only bone of the arm. It articulates with the scapula at the shoulder and with the forearm at the elbow. The forearm extends from the elbow to the wrist and consists of two bones: the ulna and the radius. The radius is located along the lateral (thumb) side of the forearm and articulates with the humerus at the elbow. The ulna is located on the medial aspect (pinky-finger side) of the forearm. It is longer than the radius. The ulna articulates with the humerus at the elbow. The radius and ulna also articulate with the carpal bones and with each other, which in vertebrates enables a variable degree of rotation of the carpus with respect to the long axis of the limb. The hand includes the eight bones of the carpus (wrist), the five bones of the metacarpus (palm), and the 14 bones of the phalanges (digits). Each digit consists of three phalanges, except for the thumb, when present, which has only two. The Pelvic Girdle The pelvic girdle attaches to the lower limbs of the axial skeleton. Because it is responsible for bearing the weight of the body and for locomotion, the pelvic girdle is securely attached to the axial skeleton by strong ligaments. It also has deep sockets with robust ligaments to securely attach the femur to the body. The pelvic girdle is further strengthened by two large hip bones. In adults, the hip bones, or coxal bones, are formed by the fusion of three pairs of bones: the ilium, ischium, and pubis. The pelvis joins together in the anterior of the body at a joint called the pubic symphysis and with the bones of the sacrum at the posterior of the body. The female pelvis is slightly different from the male pelvis. Over generations of evolution, females with a wider pubic angle and larger diameter pelvic canal reproduced more successfully. Therefore, their offspring also had pelvic anatomy that enabled successful childbirth (Figure 38.13). Q: Any place at which two bones are joined is called a what? Choices: - modification - constriction - expression - articulation A:
(Answer)
articulation
Ques: Answer the following question given this paragraph: Lions live in social groups called prides . Adult females in the pride hunt cooperatively, which is more efficient than hunting alone. Then they share the food with the rest of the pride. For their part, adult males defend the pride's territory from other predators. Q: What is a group of lions called? Choices: - coven - herd - bevy - pride A:
Ans: pride

Answer the following question given this paragraph: Another amazing feature on the Sun is solar prominences. Plasma flows along the loop that connects sunspots. This plasma forms a glowing arch. The arch is a solar prominence. Solar prominences can reach thousands of kilometers into the Sun's atmosphere. Prominences can last for a day to several months. Prominences can be seen during a total solar eclipse. Q: What is the arch called that forms when plasma of the sun flows along the loop that connects sunspots? Choices: - Energy prominence. - vertical prominence - large prominence - solar prominence A:
(A).
solar prominence
Ques:Answer the following question given this paragraph: A magnet is an object that attracts certain materials such as iron. All magnets have north and south magnetic poles. The poles are regions where the magnet is strongest. Q: In a magnet, what are the regions called that are the strongest? Choices: - positives - plates - negatives - poles A:

Ans:poles
Answer the following question given this paragraph: Savannas Savannas are grasslands with scattered trees, and they are found in Africa, South America, and northern Australia (Figure 20.18). Savannas are hot, tropical areas with temperatures averaging from 24oC 29oC (75oF 84oF) and an annual rainfall of 51127 cm (2050 in). Savannas have an extensive dry season and consequent fires. As a result, scattered in the grasses and forbs (herbaceous flowering plants) that dominate the savanna, there are relatively few trees (Figure 20.20). Since fire is an important source of disturbance in this biome, plants have evolved well-developed root systems that allow them to quickly re-sprout after a fire. Q: What type of landscape has grasslands with scattered trees, are hot and have extensive dry seasons along with fire? Choices: - deserts - arctic - tundra - savannas A:
savannas
