- Question
Which of the following foods does not support bacterial growth?
Options- A. Raw carrots
- B. Sauted onions
- C. Refried beans
- D. Cooked rice
- Correct Answer
- Raw carrots
ExplanationCooked food create an enabling environment for bacteria to grow because of their moisture content and because of the normal temperature of the food. Raw food does not offer suitable conditions for bacteria growth.
Hence, raw carrots does not support bacterial growth.

Correct Answer: capillaries of the active muscles will be engorged with blood.
Explanation:
During vigorous exercise capillaries of the active muscles will be engorged with blood.
Correct Answer: moderate tempatures
Explanation:
The moderate temperatures allow Earth to maintain bodies of water into its normal state.
Changes in the bodies of water in terms of volume and structure would change due to the change in temperature.
Correct Answer: 3
Explanation:
Tablespoon > Teaspoon
In US & UK, 1 Tablespoon = 3 Teaspoons.
Correct Answer: 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.
Correct Answer: impair the racial qualities of future generations either physically or mentally
Explanation:
Eugenics is the study of altering human beings by changing their genetic components.
It is the study of the agencies under social control that may improve or impair the racial qualities of future generations either physically or mentally.
Correct Answer: Talc
Explanation:
Cosmetic powders are prepared from Talc.
Face powder is a cosmetic powder applied to the face to set a foundation after application. It can also be reapplied throughout the day to minimize shininess caused by oily skin. There is translucent sheer powder, and there is pigmented powder.
Correct Answer: Sulphur
Explanation:
Sulfur vulcanisation is a chemical process for converting natural rubber or related polymers into more durable materials by heating them with sulfur. By this they achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.
Correct Answer: Corona
Explanation:
The outermost layer of the sun is called The Corona.
The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region.
Correct Answer: Light
Explanation:
Light travels Faster than Sound.
Light :
1. Light doesn't require a medium to travel.
2. It travels in the vaccum with the speed of 1,86,000 miles per second.
Sound:
1. Sound rquire a medium.
2. It travels in the Air with the speed of 340 meters per second.
3. It travels Faster in Water than in Air.
4. It travels Faster in Steel than in Water.
Correct Answer: Fungi
