- Question
Soil erosion can be prevented by
Options- A. Removal of vegetation
- B. Overgrazing
- C. Afforestation
- D. Increasing bird population
- Correct Answer
- Afforestation
ExplanationThe 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.

Correct Answer: A, B, E, G
Explanation:
Plasmodium is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects.
From the above given options, A, B, E, G are TRUE regarding Plasmodium.
Correct Answer: high physiological age
Correct Answer: Anemophily
Explanation:
Pollination by wind is called Anemophily or Wind pollination. The process of the transfer of pollen from one individual plant to another, whereby the pollen is carried by air currents is called Anemophily.
Almost all gymnosperms (Non-flowering plants) are anemophilous, as are many plants in the order Poales, including grasses, sedges and rushes.
Correct Answer: 1901
Correct Answer: Rich in Beta-Carotene
Explanation:
Golden Rice (Oryza sativa) denotes a genetically modified rice capable of biosynthesizing and accumulating ?-carotene (provitamin A) in the endosperm, yielding a characteristic yellow color in the polished grains. Golden rice was developed to help cope with vitamin A deficiency, a problem that prevails in developing countries, affecting millions (Underwood, 2000; UNICEF, 2000). Vitamin A deficiency causes mortality and growth retardation in children and frequently impairs vision, leading to blindness. It also contributes indirectly to anemia by interfering with iron bioavailability.
The endosperm of Golden Rice (Oryza sativa) is yellow due to the accumulation of ?-carotene (provitamin A) and xanthophylls. The product of the two carotenoid biosynthesis transgenes used in Golden Rice results in Pale Yellow color.
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.
Correct Answer: Telemetry
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.
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.
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.
