Answer the following question given this paragraph: Particles of a hypothetical ideal gas have no significant volume and do not attract or repel each other. In general, real gases approximate this behavior at relatively low pressures and high temperatures. However, at high pressures, the molecules of a gas are crowded closer together, and the amount of empty space between the molecules is reduced. At these higher pressures, the volume of the gas molecules themselves becomes appreciable relative to the total volume occupied by the gas (Figure 9.36). The gas therefore becomes less compressible at these high pressures, and although its volume continues to decrease with increasing pressure, this decrease is not proportional as predicted by Boyle's law. Q: At high pressures, how are the molecules of a gas crowded? Choices: - few together - further apart - small together - closer together A:
closer together

Ques: Answer the following question given this paragraph: Medications that can result in edema include vasodilators, calcium channel blockers used to treat hypertension, nonsteroidal anti-inflammatory drugs, estrogen therapies, and some diabetes medications. Underlying medical conditions that can contribute to edema include congestive heart failure, kidney damage and kidney disease, disorders that affect the veins of the legs, and cirrhosis and other liver disorders. Therapy for edema usually focuses on elimination of the cause. Activities that can reduce the effects of the condition include appropriate exercises to keep the blood and lymph flowing through the affected areas. Other therapies include elevation of the affected part to assist drainage, massage and compression of the areas to move the fluid out of the tissues, and decreased salt intake to decrease sodium and water retention. Q: Activities that can reduce the effects of what condition include exercises to keep the blood and lymph flowing through affected areas? Choices: - anemia - inflammation - asthma - edema A:
Ans: edema

Answer the following question given this paragraph: Carbohydrates include sugars, starches, and fiber. Sugars and starches are used by the body for energy. One gram of carbohydrates provides 4 Calories of energy. Fiber, which is found in plant foods, cannot be digested but is needed for good health. Simple carbohydrates are small carbohydrates found in foods such as fruits and milk. These carbohydrates include lactose, fructose and glucose. Complex carbohydrates are much larger molecules. Starch, which is a complex carbohydrate found in vegetables and grains, is made of thousands of glucose units bonded together. Q: What category of food includes sugars, starches and fibers? Choices: - enzymes - proteins - alcohols - carbohydrates A:
(A).
carbohydrates
Ques:Answer the following question given this paragraph: Q: Within each sporangium, hundreds of what kind of spores develop and are dispersed through the air? Choices: - diploid - polyploid - infertile - haploid A:

Ans:haploid
Ques:Answer the following question given this paragraph: Assume you are finding the area of a rectangle with a length of 6.8 m and a width of 6.9 m. When you multiply the length by the width on your calculator, the answer you get is 46.92 m 2 . Is this the correct answer? No; the correct answer is 46.9 m 2 . The correct answer must be rounded down so there is just one digit to the right of the decimal point. That's because the answer cannot have more digits to the right of the decimal point than any of the original measurements. Using extra digits implies a greater degree of precision than actually exists. The correct number of digits is called the number of significant figures . To learn more about significant figures and rounding, you can watch the videos at the URLs below. Q: What two measurements are multiplied to find the area of a rectangle? Choices: - depth and width - volume and mass - length and depth - length and width A:

Ans:
length and width
