Answer the following question given this paragraph: of the proximal tibia. This versatile muscle flexes the leg at the knee and flexes, abducts, and laterally rotates the leg at the hip. This muscle allows us to sit cross-legged. The posterior compartment of the thigh includes muscles that flex the leg and extend the thigh. The three long muscles on the back of the knee are the hamstring group, which flexes the knee. These are the biceps femoris, semitendinosus, and semimembranosus. The tendons of these muscles form the popliteal fossa, the diamond-shaped space at the back of the knee. Q: The three long muscles on the back of the knee are part of which group? A:
****
A: hamstring group

Answer the following question given this paragraph: greater amount of chyme at one time would overwhelm the capacity of the small intestine to handle it. The rest of the chyme is pushed back into the body of the stomach, where it continues mixing. This process is repeated when the next mixing waves force more chyme into the duodenum. Gastric emptying is regulated by both the stomach and the duodenum. The presence of chyme in the duodenum activates receptors that inhibit gastric secretion. This prevents additional chyme from being released by the stomach before the duodenum is ready to process it. Q: Gastric emptying is regulated by both the stomach and what other digestive structure? A:
OPTIONS:
- small intestine
- appendix
- esophagus
- duodenum
duodenum

Answer the following question given this paragraph: In this lesson, you read that air density and pressure change with altitude. The temperature of the air also changes with altitude. Air temperature measures the heat energy of air molecules. Q: What does temperature measure? A:
OPTIONS:
- lowest kinetic energy of molecules
- average potential energy of molecules
- highest potential energy of molecules
- average kinetic energy of molecules

Answer: average kinetic energy of molecules

input with options: Answer the following question given this paragraph: Accuracy and Precision of a Measurement Science is based on observation and experimentthat is, on measurements. Accuracy is how close a measurement is to the correct value for that measurement. For example, let us say that you are measuring the length of standard computer paper. The packaging in which you purchased the paper states that it is 11.0 inches long. You measure the length of the paper three times and obtain the following measurements: 11.1 in. , 11.2 in. , and 10.9 in. These measurements are quite accurate because they are very close to the correct value of 11.0 inches. In contrast, if you had obtained a measurement of 12 inches, your measurement would not be very accurate. The precision of a measurement system is refers to how close the agreement is between repeated measurements (which are repeated under the same conditions). Consider the example of the paper measurements. The precision of the measurements refers to the spread of the measured values. One way to analyze the precision of the measurements would be to determine the. Q: How close a measurement is to the correct value for that measurement is known as what? A:
OPTIONS:
- frequency
- rate
- temperature
- accuracy
output:
accuracy
