input with options: Answer the following question given this paragraph: Physical Therapist As muscle cells die, they are not regenerated but instead are replaced by connective tissue and adipose tissue, which do not possess the contractile abilities of muscle tissue. Muscles atrophy when they are not used, and over time if atrophy is prolonged, muscle cells die. It is therefore important that those who are susceptible to muscle atrophy exercise to maintain muscle function and prevent the complete loss of muscle tissue. In extreme cases, when movement is not possible, electrical stimulation can be introduced to a muscle from an external source. This acts as a substitute for endogenous neural stimulation, stimulating the muscle to contract and preventing the loss of proteins that occurs with a lack of use. Physiotherapists work with patients to maintain muscles. They are trained to target muscles susceptible to atrophy, and to prescribe and monitor exercises designed to stimulate those muscles. There are various causes of atrophy, including mechanical injury, disease, and age. After breaking a limb or undergoing surgery, muscle use is impaired and can lead to disuse atrophy. If the muscles are not exercised, this atrophy can lead to long-term muscle weakness. A stroke can also cause muscle impairment by interrupting neural stimulation to certain muscles. Without neural inputs, these muscles do not contract and thus begin to lose structural proteins. Exercising these muscles can help to restore muscle function and minimize functional impairments. Age-related muscle loss is also a target of physical therapy, as exercise can reduce the effects of age-related atrophy and improve muscle function. The goal of a physiotherapist is to improve physical functioning and reduce functional impairments; this is achieved by understanding the cause of muscle impairment and assessing the capabilities of a patient, after which a program to enhance these capabilities is designed. Some factors that are assessed include strength, balance, and endurance, which are continually monitored as exercises are... Q: What kinds of cells that are important to our physical functioning can atrophy when they are not used? A:

Q: Answer the following question given this paragraph: Normally blood needs to flow freely through our arteries. Plaque in an artery can restrict the flow of blood. As you can probably imagine, this is not an ideal situation. And eating right, exercising, and not smoking can help keep your arteries healthy. Q: What impact can plaque in an artery have on the flow of blood? A:

OPTIONS:
- no effect
- allergic reaction
- increased flow
- restriction

A: restriction

input: OPTIONS:
- ions or hormones
- acids and bases
- enzymes and acids
- solid ions or molecules Now, answer this question: Answer the following question given this paragraph: Motion of water molecules helps break up interactions between solid ions or molecules. Q: Motion of water molecules helps break up interactions between what? A:
A:
output: solid ions or molecules

Answer the following question given this paragraph: Both mammals and birds evolved endothermy. Endothermy means controlling body temperature within a narrow range from the inside through biochemical or physical means. For example, on a cold day, an endotherm may produce more body heat by increasing its rate of metabolism. On a hot day, it may give off more heat by increasing blood flow to the surface of the body. That way, some of the heat can radiate into the air from the body's surface. Endothermy requires more energy (and food) than ectothermy. However, it allows the animal to stay active regardless of the temperature outside.

Q: What term means controlling body temperature within a narrow range from the inside through biochemical or physical means? A:

OPTIONS:
- exothermy
- regulation
- evaporation
- endothermy

Answer: endothermy

Problem: OPTIONS:
- noble gases
- the acid group
- metalloids
- the oxygen group
Q: Answer the following question given this paragraph: Group 16 is called the oxygen group. The first three elements in this group are nonmetals. They are followed by one metalloid and one metal. All the elements in the oxygen group have six valence electrons, and all are reactive. Oxygen (O), for example, readily reacts with metals to form compounds such as rust. Oxygen is a gas at room temperature. The other four elements in group 16 are solids. Q: Group 16 is called what? A:
Answer: the oxygen group
