steak the most?

In your stomach.

When we did the egg white

experiment, we had to let the egg

white sit in the liquids overnight.

When we did the amylase

experiment, we tested for starch andsugar after only 5 minutes.

Why did we have to wait such a longtime for the egg white, but not for

the amylase?


31/51

31

Because the amylase

experiment was about yourmouth. Food stays in your

mouth for a short amount of

time. But the egg white

experiment was about your

stomach. Food stays in yourstomach for several hours!

A man named Stuart got into a

serious accident. He lost half of

his large intestine. His waste

could still leave through the

rectum, but half of the large

intestine was missing. What

problem do you think he was

likely to have?

Your large intestine absorbs

water. So if you lose some of your

large intestine, less water will beabsorbed, making your waste

more watery and giving you

Diarrhea!
