Question 1

A muscle cramp happens when the muscle becomes contracted and rigid,and iscommonly associated with _____.&#10;A)drinking too much water&#10;B)lack of exercise&#10;C)not eating enough bananas&#10;D)too much exercise

Accepted Answer

Muscle cramps are commonly associated with too much exercise, as the muscles can become fatigued and overworked leading to cramping. Drinking too much water or not eating enough bananas are not typically associated with muscle cramps, and lack of exercise could potentially lead to muscle weakness but not necessarily cramping.

Question 2

Gas chromatography measures the caloric content of foods.

Accepted Answer

Gas chromatography is a technique used in chemistry to separate, identify, and quantify components in a mixture. It is not used to measure the caloric content of foods. Caloric content is generally measured using techniques such as bomb calorimetry or by calculating the energy value from the macronutrient composition of the food.

Question 3

The definition generally accepted in the United States and standard in thermochemistry is1 cal equals _____ joules (J)&#8203;.&#10;A)4.1840&#10;B)5.2840&#10;C)3.5840&#10;D)6.0840

Accepted Answer

The definition of one calorie (cal) as accepted in the United States and standard in thermochemistry is 4.1840 joules (J). Therefore, choice A is the correct answer.

Question 4

The first system of approximating the value of a food for nutritional purposes became known as _____.&#10;A)spectrophotomety&#10;B)liquid chromatography&#10;C)gas chromatography&#10;D)proximate analysis

Accepted Answer

The first system of approximating the value of a food for nutritional purposes is known as proximate analysis. It involves the determination of the amounts of protein, fat, moisture, ash, and fiber in a food sample. Spectrophotometry, liquid chromatography, and gas chromatography are analytical techniques used for measuring specific compounds or components in a food sample.

Question 5

Energy in food is measured in terms of calorimeters.

Accepted Answer

Energy in food is measured in terms of calories, not calorimeters. Calorimeters are devices used to measure the heat of chemical reactions or physical changes, including the calorific value of foods.

Question 6

Eating foods high in sodium and potassium can relieve muscle cramps.

Accepted Answer

Sodium and potassium are important electrolytes that help regulate muscle function. Consuming foods high in these minerals can help prevent and alleviate muscle cramps.

Question 7

_____ often will relieve muscle cramps.&#10;A)Drinking electrolyte drinks&#10;B)Drinking milk&#10;C)Avoiding foods with potassium&#10;D)Avoiding foods high in sodium

Accepted Answer

Drinking electrolyte drinks, such as Gatorade or Powerade, can help relieve muscle cramps. These drinks contain the electrolytes sodium, potassium, magnesium, and calcium, which can help replenish the body's lost electrolytes and prevent muscle cramping. Milk and foods high in potassium can also be beneficial for preventing muscle cramps, but avoiding foods high in sodium is not recommended as sodium is an important electrolyte that helps regulate fluid balance in the body.

Question 8

The term charley horse is most often used in connection with athletes,especially baseball players.

Accepted Answer

The term charley horse refers to a painful muscle spasm, and while it can happen to athletes, it is not exclusive to them. It can happen to anyone, regardless of their level of physical activity.

Question 9

The nutrient content of foods is influenced by variety,season,geographical differences,stage of harvesting,handling,commercial processing,packaging,storage,display,home preparation,cooking,and serving.

Accepted Answer

The nutrient content of foods can indeed be influenced by various factors such as the ones mentioned, including variety, season, and how they are prepared and processed.

Question 10

Methods such as liquid chromatography and gas chromatography determine the composition of foods.

Accepted Answer

Liquid chromatography and gas chromatography are analytical techniques that can be used to determine the components and composition of foods. These techniques involve separating and analyzing the different molecules in a sample, often by utilizing a stationary phase (such as a column filled with a solid or liquid) and a mobile phase (such as a solvent or gas). This allows scientists to identify and quantify the specific molecules present in a food sample.
