- 3. Soil erosion can be prevented by
Options- A. Removal of vegetation
- B. Overgrazing
- C. Afforestation
- D. Increasing bird population Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO
Correct Answer: Afforestation
Explanation:
The four most common soil erosion prevention methods are vegetation, geotextiles, mulch, and retaining walls.
By planting grass in areas of concentrated water flow, farmers can prevent much of the soil erosion that results from runoff, as the grass stabilizes the soil while still providing an outlet for drainage.
Preventing soil erosion is critical in protecting your property and exposed soil, whether from wind, weather, running water, and even the after-effects of the forest fire.
- 4. Fuse Wire is Made of?
Options- A. an alloy of Tin and Lead
- B. Nickel
- C. Copper
- D. an alloy of Nickel and Lead Also asked in: AIEEE, Bank Exams, CAT, GATE, GRE, Analyst, Bank PO, Database Administrator, IT Trainer
Correct Answer: an alloy of Tin and Lead
Explanation:
Fuse Wire is Made of an alloy of Tin and Lead.
If too high a current flows, the element rises to a higher temperature and either directly melts, or else melts a soldered joint within the fuse, opening the circuit. Thefuse element is made of an alloy of Tin and Lead to provide stable and predictable characteristics.
- 5. What is the measurement at remote distances by means of a radio -link from the object to the ground called? Discuss
Correct Answer: Telemetry
- 6. The Biggest cause of Foodborne Illness is
Options- A. Poor Hygiene
- B. Toothpick
- C. Employee snacking
- D. Virus Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO
Correct Answer: Poor Hygiene
Explanation:
The Biggest cause of Foodborne Illness is Poor Personal Hygiene.
Foodborne Illness is caused by consuming contaminated foods or beverages. Many different disease-causing microbes or pathogens can contaminate foods, so there are many different types of foodborne illnesses.
- 7. A Disease which spreads by contact?
Options- A. Infectious
- B. Fatal
- C. Incurable
- D. Contagious Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk, Bank PO
Correct Answer: Contagious
Explanation:
A Disease which spreads by contact are Contagious.
Infectious diseases : These are caused by microscopic germs such as bacteria or viruses that get into the body and cause problems. Some but not all infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious. Some infections spread to people from an animal or insect, but are not contagious from another human.
Contagious diseases such as the flu, colds, or strep throat spread from person to person in several ways. One way is through direct physical contact, like touching or kissing a person who has the infection. Another way is when an infectious microbe travels through the air after someone nearby sneezes or coughs.
Fatal Diseases : Diseases leading to failure or disaster.
Incurable Diseases : Diseases of a sick person not able to be cured.
- 8. Where are the Macronutrients located on a Nutritional Label?
Options- A. On the Top
- B. On the Right
- C. On the Bottom
- D. On the Left Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO
Correct Answer: On the Top
Explanation:
Macronutrients are located on the Top of a Nutritional Label.
Macronutrients are essential substances that the body needs to survive and develop. There are 3 main Macronutrients:
1. Fats
2. Proteins (and)
3. Carbohydrates.
The nutritional label is an important part of any food package. Since the Macronutrients refer to a list of nutrients that we need daily in a pretty large amount are the most important nutrients to sustain our living, commonly they are written on the top of the Nutrition Labels.
- 9. Eugenics is the study of
Options- A. impair the racial qualities of future generations either physically or mentally
- B. different races of mankind
- C. genetic of plants
- D. people of European origin Also asked in: AIEEE, Bank Exams, CAT, Analyst, Bank Clerk, Bank PO
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.
- 10. Which of the following is not an intensive property?
Options- A. Weight
- B. Density
- C. Refractive index
- D. Melting point Also asked in: GATE, Bank Exams, AIEEE, Bank Clerk, Analyst
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.
