ELEN [110]

Answer:

Total 495 liters of natural oil are needed.

Explanation:

It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil.

It means the ratio of natural oil and synthetic oil is

\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{5}{5+3}=\frac{5}{8}

Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.

It means the ratio of natural oil and synthetic oil is

\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{x}{792}

Equate both ratios,

\frac{x}{792}=\frac{5}{8}

On cross multiplication we get

8\times x=5\times 792

8x=3960

Divide both sides by 8.

x=\frac{3960}{8}

x=495

Therefore total 495 liters of natural oil are needed.

The picture represents a protein in the stomach being broken down into individual amino acids. Which is mixed with proteins to b
Alexeev081 [22]

Answer: The correct answer is Enzymes.

Process of digestion involves the breakdown of large complex molecules ( like carbohydrates, and proteins) present in the food into smaller soluble molecules ( like glucose and amino acids) that can be absorbed by bloodstream and transported to various body organs.

Protein in the stomach is broken down into amino acids with the help of enzyme called as pepsin ( a protease). It is an endo-peptidase that is produced in the stomach and helps in the digestion of proteins at acidic pH of the stomach ( 1.5 to 2).
