Answer:

The route of entry is absorption.

Explanation:

Hazardous chemicals can enter the body of a person by processes such as inhalation, absorption, ingestion and injection.

If a hazardous chemical, such as sodium hydroxide, enters the body of a researcher through the eyes or through contact with the skin, then such a method of the entrance is termed as absorption. The epidermis and dermis layer of the skin can absorb various chemicals which will then be transferred into the bloodstream.

The label on a granola cereal box indicates that it contains 40 grams of total carbohydrate, 13 grams of sugar, and 240 Calories

MArishka [77]

Answer:

b. 22%

Explanation:

In order to calculate the percent of calories coming from sugar, it is necessary to know that

1 g of sugar provides 4 calories.

It is provided in the question that,

There are 13 grams of sugar in one serving of granola cereal box.
There are 240 calories in one serving of granola cereal box.

Calculating the calories coming from sugar,

13 x 4= 52 calories

Hence, calculating the percent of calories coming from sugar,

$\frac{52}{240}$ x100 = 21.6% approximated to 22%

Therefore, 22% of calories come from sugar in a serving of granola cereal box.
