Answer:

It consists of the mouth, or oral cavity, with its teeth, for grinding the food, and its tongue, which serves to knead food and mix it with saliva; the throat, or pharynx; the esophagus; the stomach; the small intestine, consisting of the duodenum, the jejunum, and the ileum; and the large intestine, consisting of the cecum, a closed-end sac connecting with the ileum, the ascending colon, the transverse colon, the descending colon, and the sigmoid colon, which terminates in the rectum. Glands contributing digestive juices include the salivary glands, the gastric glands in the stomach lining, the pancreas, and the liver and its adjuncts—the gallbladder and bile ducts. All of these organs and glands contribute to the physical and chemical breaking down of ingested food and to the eventual elimination of nondigestible wastes.

Answer:

1. Decibels

2. whisper - 20-decibels, normal talking - 60 decibels, rock concert - 120 decibels

3. 10,000

4. A Jet plane

Explanation:

1. The unit refers to what specifically is being measured. If the graph was of heights, it could be metres, centimetres, feet, or inches, for example. In this case, the graph is of sound level. We can see beside the Y axis label "Sound Level" that the unit is decibels.

2. Take each individual sound source and look at how tall the bars are (purple rectangles). For each one, we can look across to the Y axis (left side) and see the corresponding sound level for each

3. We were told in the introduction to the question that for every 10 decibel increase, the sound increases by 10 times. So going from 10 -> 20 decibels represents a 10x increase, and 10-> 30 represents a 100x increase.  

To figure out the increase from whisper (20) to normal talking (60), take away 20 from 60 to see how many decibels difference there are between the two levels.

60-20 = 40

There is a 40 decibel increase. If 10 decibel difference = 10x and 20 decibel difference = 100x, then 30 = 1000x, and 40 = 10,000x (keep adding a 0 with every 10!)

4. We can see from the graph that the pain threshold is 120 decibels. The sound level that is greater than the pain threshold (meaning it would be painful) is the jet plane.
