C) Saturn D) Neptune
 
Answer & Explanation Answer: B) Earth

Within the Solar System, four Jovian planets exist – Jupiter, Saturn, Uranus, and Neptune. Though these planets vary in terms of size, mass, and composition, they all share certain characteristics that cause them to differ greatly from the terrestrial planets located in the inner Solar System.

Q:

Pulses are a good source of

A) Proteins B) Fats
C) Vitamins D) Carbohydrates
 
Answer & Explanation Answer: A) Proteins

Explanation:

A pulse is an edible seed that grows in a pod. Pulses include all beans, peas, and lentils.
Pulses are a great source of protein.

This means they can be particularly important for people who do not get protein by eating meat, fish or dairy products.

 

However, pulses can also be a healthy choice for meat-eaters. You can add pulses to soups, casseroles and meat sauces to add extra texture and flavor. This means you can use less meat, which makes the dish lower in fat and cheaper.

Q:

Soil erosion can be prevented by

A) Removal of vegetation B) Overgrazing
C) Afforestation D) Increasing bird population
 
Answer & Explanation Answer: C) 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.
