Q:

At what temperature do pathogenic bacteria grow best in food?

A) 5 to 15 degrees Celsius B) 15 to 25 degrees Celsius
C) 20 to 45 degrees Celsius D) 40 to 65 degrees Celsius
 
Answer & Explanation Answer: C) 20 to 45 degrees Celsius

Explanation:

The Bacteria that causes Food Borne illness are called Food Borne Pathogens. Most of the pathogens are mesophilic in nature, optimum temperature may be around 20-45 degree celsius. This range of temperatures is often called the "Danger Zone." Dry foods do not support the growth of bacteria.

 

In order to kill pathogenic bacteria you need temperatures above 74ºC. Temperature is the easiest factor to control in order to prevent bacterial growth.

Q:

Which of the following is not an intensive property?

A) Weight B) Density
C) Refractive index D) Melting point
 
Answer & Explanation Answer: A) Weight

Explanation:

An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system, if the system is divided in half, the mass and the volume change in the identical ratio and the density remains unchanged. Additionally, the boiling point of a substance is another example of an intensive property. For example, the boiling point for water is 100 °C at a pressure of one atmosphere, a fact which remains true regardless of quantity.

Q:

What comes next in this sequence

196, 169, 144, 121, 100, 81, ?

A) 77 B) 74
C) 67 D) 64
 
Answer & Explanation Answer: D) 64

Explanation:

The given number series follows a pattern that

196, 169, 144, 121, 100, 81, ?

    -27  -25   -23   -21  -19  -17

 

=> 81 - 17 = 64

Therefore, the series is 196, 169, 144, 121, 100, 81, 64.

Q:

Which layer of the atmosphere contains the ozone layer?

A) Troposphere B) Stratosphere
C) Thermosphere D) Mesosphere
 
Answer & Explanation Answer: B) Stratosphere

Explanation:

The ozone layer is a region of Earth's Stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

 

The Atmosphere is divided into 4 layers according to major changes in temperature. They are :

1. Troposphere,

2. Stratosphere,

3. Mesosphere  and

4. Thermosphere.

The farther away from earth, the thinner the atmosphere gets.
