Here, we would choose "Myobacterium Tuberculae", which 'causes Tuberculosis in Humans.

It is spreadable disease and highly contagious, and communicate very rapidly, so when it first appeared, it was very difficult task to prevent ourselves from that Hazardous condition.

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.
