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 refrigerator must do work to reverse the normal direction of thermal energy flow. Work involves the use of force to move something, and doing work takes energy. In a refrigerator, the energy is usually provided by electricity. You can read in detail in the Figure below how a refrigerator does its work. For an animation of how a refrigerator works, go to this URL: http://www. chemistry. wustl. edu/~edudev/LabTutorials/CourseTutorials/LabTutorials/Thermochem/fridge_movie. html. Q: A refrigerator must do work to reverse the normal direction of what? Choices: - visible energy flow - coolant energy flow - spectral energy flow - thermal energy flow A:
(Answer)
thermal energy flow
Ques: Answer the following question given this paragraph: Ohm's law may be easier to understand with an analogy. Current flowing through a wire is like water flowing through a hose. Increasing voltage with a higher-volt battery increases the current. This is like opening the tap wider so more water flows through the hose. Increasing resistance reduces the current. This is like stepping on the hose so less water can flow through it. If you still aren't sure about the relationships among current, voltage, and resistance, watch the video at this URL: http://www. youtube. com/watch?v=KvVTh3ak5dQ. Q: Increasing voltage with a higher-volt battery does what to the current? Choices: - blocks it - stops it - decreases it - increases it A:
Ans: increases it
(Q).
Answer the following question given this paragraph: Segmentation evolved next. Segmentation is the division of the body into multiple parts, or segments. Both the earthworm (Phylum Annelida) in Figure below and ant (Phylum Arthropoda) in Figure below have segmented bodies. The earthworm has many small segments. The ant has three larger segments. Segmentation increases an animal's flexibility. It allows a wider range of motion. Different segments can also be specialized for different functions. All modern annelids and arthropods are segmented. Q: Earthworms and ants possess what type of bodies, which means division into multiple parts? Choices: - elongated - truncated - elliptical - segmented A:
(A).
segmented
Ques:Answer the following question given this paragraph: Bioluminescent organisms include jellyfish and fireflies. Jellyfish give off visible light to startle predators. Fireflies give off visible light to attract mates. Q: What do jellyfish use to startle predators? Choices: - black light - bicellular light - harsh light - visible light A:

Ans:visible light
Question: Answer the following question given this paragraph: A: The modern kinetic theory of matter is remarkably similar to Democritus' ideas about the motion of atoms. According to this theory, atoms of matter are in constant random motion. This motion is greater in gases than in liquids, and it is greater in liquids than in solids. But even in solids, atoms are constantly vibrating in place. Q: What theory says atoms of matter are in constant random motion? Choices: - the theory of relativity - modern residual theory - sound kinetic theory - modern kinetic theory A:
Answer:
modern kinetic theory
