Saliva that covers the food particles is produced by salivary glands in the mouth cavity. Salivary amylase is an enzyme found in saliva.

Dietary carbohydrates are converted to glucose, fructose, and/or galactose in the small intestine and then absorbed into the blood. The breakdown and absorption of dietary carbohydrates can be influenced by a variety of factors.

What mass of water in grams will fill a fish tank 100 cm long, 50 cm wide, and 30 cm high?
Natasha_Volkova [10]

Answer:

150,000cm^3, or 1,500m^3

Explanation:

The question is basically asking the volume of this rectangular tank.

The formula to find the volume is length x width x height.

This is because we're trying to find the area of the base (length x width), and then we're multiplying the base times the height, to get how much of the base area can fit in the height of the rectangle.

So, the answer is 100cm x 50cm x 30cm = 150,000cm^3, or 1,500m^3, because 1 meter = 100 centimeters.
