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? A:
****
A: skeletal and muscular

Answer the following question given this paragraph: Ceres ( Figure below ) is a rocky body that orbits the Sun. It could be an asteroid or a planet. Before 2006, Ceres was thought to be the largest asteroid. Is it an asteroid? Ceres is in the asteroid belt. But it is by far the largest object in the belt. Ceres has such high gravity that it is spherical. Q: What explains the spherical shape of ceres, once thought to be the largest asteroid? A:
OPTIONS:
- orbital plane
- space debris
- low gravity
- high gravity

Answer: high gravity
