truth table:


A B output


1 1 0


0 0 1


The second way is passing the input to only one input (say A) of the NAND gate. Since the other input  (say B is floating, it is always logic one.

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.

C) Vitamins A, D & K D) Vitamins A, K, B, C & D
 
Answer & Explanation Answer: A) Vitamins B & C

Explanation:

Vitamins are essential nutrients found in foods. They perform specific and vital functions in a variety of body systems, and are crucial for maintaining optimal health.

 

The two different types of vitamins are fat-soluble vitamins and water-soluble vitamins.

 

Fat-soluble vitamins :

 Vitamins A, D, E and K — dissolve in fat before they are absorbed in the bloodstream to carry out their functions. Excesses of these vitamins are stored in the liver, and are not needed every day in the diet.

 

Water-soluble vitamins :

Vitamins dissolve in water and are not stored by the body. Since they are eliminated in urine, we require a continuous daily supply in our diet. The water-soluble vitamins include the vitamin B-complex group and vitamin C.

 

Water-soluble vitamins are easily destroyed or washed out during food storage or preparation.
