Answer:
Hydroponics solves the problem of unavailability of water in those arid and dry regions
Explanation:
As rightly stated in the question, hydroponics is a practice that involves the culturing of plants without the need for soil. Hydroponics procedure make use of a moisture-containing solution filled with nutrients.
This procedure of hydroponics, however, comes with some disadvantages but one major effectiveness it has in arid or dry regions is that it SOLVES THE PROBLEM OF WATER UNAVAILABILITY. When it comes to farming practice using soil, constant water supply is an unnegotiable criterion because water is needed for the growth of plants in the soil.
However, in arid regions, which are usually very dry due to lack of rainfall, the practice of hydroponics can substitute for soil farming in order not to cause food scarcity.

Explanation:
- Make a hypothesis about which part of the light spectrum causes the most plant growth and which part of the light spectrum causes the least plant growth. Assume that all conditions other than the color of the light are the same for each seed as it grows: the soil, moisture, viability of the seed, etc. State your hypothesis on your lab worksheet. Example: If a plant is grown under Red and Blue color of light then the plant will grow well. However, if the plant is grown under Green color light then the plant will not grow well.
- All the VIBGYOR color is mixed all together and forms the White color. Plants are green because chlorophyll reflects the green light and absorbs the other light spectrums. If the Blue light spectrum is absorbed then the plant will grow the most and if the Greenlight spectrum is absorbed then the plant will grow the least.
