Selected Answer: Tru e Answers: Tru e False Question 13 2.2 out of 2.2 points Which organ system protects organs, allows for support and movement, and also plays a key role in blood formation? Selected Answer: Skeletal system Answers: Circulatory system Muscular system Skeletal system Nervous system Response Feedback: The skeletal system protects organs, gives the body support and allows it to move, and also plays a role in the formation of blood cells. The circulatory system distributes oxygen, nutrients, water, hormones, and other electrolytes; it also has a role in fluid and electrolyte balance. The muscular system allows the body to move and produces heat. The nervous system regulates and coordinates other systems, and also has a role in sensation and memory. Question 14 16.6 out of 16.6 points Match each term to its definition.

Muscle contracts to produce movement. Nerve tissue generates and transmits impulses to regulate body function. Question 18 2.2 out of 2.2 points The constancy of the body’s internal environment is called homeostasis. Selected Answer: Tru e Answers: Tru e False CHAPTER 2 Question 1 2.3 out of 2.3 points Which four elements make up more than 96% of the human body?

Calcium, iron, and sodium are critically important to the body’s structure and function but combined they make up less than 2% of its mass. Question 2 2.3 out of 2.3 points How do cells obtain energy? Selected Answer: Cells break bonds in ATP molecules. Answers: Energy is made in the liver and released into the blood for the cells to use. Cells break down protein molecules. Energy stored as fat is released into the blood. Cells break bonds in ATP molecules. Response Feedback: Cells obtain energy by breaking phosphate bonds in the ATP molecule. The liver does not release energy into the bloodstream; cells release energy when they need it. Proteins, fats, and carbohydrates can all be used for energy production; however, those substances must first be converted to ATP. Question 3 2.3 out of 2.3 points Covalent bonds form when Selected Answer: two atoms share electrons to fill their outer shells. Answers: positively charged hydrogen atoms attract negatively charged atoms. electrostatic forces bring atoms together to form a new molecule. two atoms share electrons to fill their outer shells. a nitrogen atom combines with a carbon atom. Response Feedback: Covalent bonding occurs when electrons are shared by two atoms so that each has a complete outer shell of eight electrons. The attraction of hydrogen atoms to oxygen atoms is an example of hydrogen bonding. Electrostatic forces pull ions together; no electrons are shared. Nitrogen and carbon are involved in peptide bonds. Question 4 2.3 out of 2.3 points Where are protons and neutrons located? Selected Answer: Protons and neutrons both reside in the nucleus. Answers: Protons and neutrons orbit the nucleus in one or more concentric clouds. Protons orbit the nucleus in a cloud, and neutrons reside in the nucleus.
