Answer the following question given this paragraph: When using measuring devices, we often use a technique called calibration to increase the accuracy of our measurements. Calibration is a method of setting or correcting a measuring device by matching it to known measurement standards. To better understand calibration, we will look at the example of calibrating a thermometer. All thermometers are slightly different in their temperature readings. One way to calibrate a thermometer is by using the freezing point and boiling point of water ( Figure below ). If we know that water freezes at 0C and boils at 100C, we can calibrate our thermometer by measuring the temperature of ice water and of boiling water. We place the thermometer in ice water and wait for the thermometer liquid to reach a stable height, then place a mark at this height which represents 0C. Then we place the thermometer in boiling water, and after waiting for the thermometer liquid to reach a stable height, we place a mark at this height which represents 100C. We can then place 100 equally spaced divisions between our 0 and 100C marks to each represent 1C. Our thermometer has now been calibrated using the known values for the freezing point and boiling point of water, and can be used to measure temperatures of objects between 0 and 100C. Q: What is the method of setting or correcting a measuring device by matching it to known measurement standards called? Choices: - parallax - distortion - precision - calibration A:
calibration
Answer the following question given this paragraph: Millions of acres of forest have been cut and burned to make way for farming. Figure below shows an example. Burning trees produces most of the same pollutants as burning fossil fuels. Q: Burning trees produces most of the same pollutants as burning what? Choices: - fossil compounds - carbon - coal fuels - fossil fuels A:
fossil fuels
Q: Answer the following question given this paragraph: Connections of Proteins to Glucose Metabolism Proteins are broken down by a variety of enzymes in cells. Most of the time, amino acids are recycled into new proteins. If there are excess amino acids, however, or if the body is in a state of famine, some amino acids will be shunted into pathways of glucose catabolism. Each amino acid must have its amino group removed prior to entry into these pathways. The amino group is converted into ammonia. In mammals, the liver synthesizes urea from two ammonia molecules and a carbon dioxide molecule. Thus, urea is the principal waste product in mammals from the nitrogen originating in amino acids, and it leaves the body in urine. Q: Amino acids broken down by metabolic process are mostly recycled into new what? Choices: - lipids - hormones - enzymes - proteins A:
A: proteins
Question: Answer the following question given this paragraph: Q: What prevents solutes that have accumulated in the xylem from leaking back into the soil solution? Choices: - the exoskeleton - the exodermis - the altostratus - the endodermis A:
Answer: the endodermis

**Answer**

Choices: - coral reefs or freshwater - oceans or estuaries - estuaries or saltwater - saltwater or freshwater A:
(Answer)
saltwater or freshwater
