Answer the following question given this paragraph: 16.5 | Musculoskeletal System By the end of this section, you will be able to: Discuss the axial and appendicular parts of the skeletal system Explain the role of joints in skeletal movement Explain the role of muscles in locomotion The muscular and skeletal systems provide support to the body and allow for movement. The bones of the skeleton protect the body's internal organs and support the weight of the body. The muscles of the muscular system contract and pull on the bones, allowing for movements as diverse as standing, walking, running, and grasping items. Injury or disease affecting the musculoskeletal system can be very debilitating. The most common musculoskeletal diseases worldwide are caused by malnutrition, which can negatively affect development and maintenance of bones and muscles. Other diseases affect the joints, such as arthritis, which can make movement difficult and, in advanced cases, completely impair mobility. Progress in the science of prosthesis design has resulted in the development of artificial joints, with joint replacement surgery in the hips and knees being the most common. Replacement joints for shoulders, elbows, and fingers are also available. Q: Which two systems together provide support to the body and allow for movement? Choices: - muscular and nervous - skeletal and digestive - vascular and muscular - skeletal and muscular A:
skeletal and muscular
Answer the following question given this paragraph: A circuit that consists of two loops is called a parallel circuit. If one loop of a parallel circuit is interrupted, current can still flow through the other loop. Q: A circuit that consists of two loops is called a what? Choices: - diverse circuit - unnatural circuit - complex circuit - parallel circuit A:
parallel circuit
Q: Answer the following question given this paragraph: Earthquakes with a magnitude in the 9 range are rare. The United States Geological Survey lists five such earthquakes on the moment magnitude scale since 1900 (see Figure below ). All but one, the Great Indian Ocean Earthquake of 2004, occurred somewhere around the Pacific Ring of Fire. Q: Since 1900, four of the five earthquakes of the greatest magnitude occurred near what appropriately nicknamed pacific location? Choices: - shower of fire - quake epicenter - seismic zone - ring of fire A:
A: ring of fire
Question: Answer the following question given this paragraph: There are also bacteria that use chemical processes to produce food. They get their energy from sources other than the sun, but they are still called producers. This process is known as chemosynthesis , and is common in ecosystems without sunlight, such as certain marine ecosystems. Q: What is the process in which producers get their energy from sources other than the sun? Choices: - electrolysis - phototropism - biosynthesis - chemosynthesis A:
Answer: chemosynthesis

Answer the following question given this paragraph: Phospholipids As its name suggests, a phospholipid is a bond between the glycerol component of a lipid and a phosphorous molecule. In fact, phospholipids are similar in structure to triglycerides. However, instead of having three fatty acids, a phospholipid is generated from a diglyceride, a glycerol with just two fatty acid chains (Figure 2.23). The third binding site on the glycerol is taken up by the phosphate group, which in turn is attached to a polar "head" region of the molecule. Recall that triglycerides are nonpolar and hydrophobic. This still holds for the fatty acid portion of a phospholipid compound. However, the head of a phospholipid contains charges on the phosphate groups, as well as on the nitrogen atom. These charges make the phospholipid head hydrophilic. Therefore, phospholipids are said to have hydrophobic tails, containing the neutral fatty acids, and hydrophilic heads, containing the charged phosphate groups and nitrogen atom. Q: A phospholipid is a bond between the glycerol component of a lipid and what else? Choices: - chlorine molecule - elemental molecule - oxygen molecule - phosphorous molecule A:
**Answer**
phosphorous molecule
Q: Answer the following question given this paragraph: Many people have vision problems. Often, the problem is due to the shape of the eyes and how they focus light. Two of the most common vision problems are nearsightedness and farsightedness. Q: What are two of the most common vision problems? Choices: - blindness and astigmatism - myopia and nearsightedness - cross-eye and blindness - nearsightedness and farsightedness A:
A: nearsightedness and farsightedness
