The groundwater is being discharged faster than it is being recharged is the data suggested.

Option D

<h3><u>Ex planation:</u></h3>

Ground water level is the level of underground storage of water above the impermeable rock layer. The underground water is getting filtered through different layers of permeable rocks before it enters the final layer. So it’s fresh and ready to be consumed as it is taken out. Thus for centuries, it’s being used as the source of drinking water.

But with increasing population, the ground water is being consumed at the rate very faster than it can be refilled from different sources like precipitation, rivers and other water bodies. So its level tends to get lower and lower as this continues until the point it gets finished.

Which nucleic acid is pictured on the right? Justify your answer.
alukav5142 [94]

Answer:

Nucleic Acids:

- Uracil

- Adenine

- Guanine

- Cytosine

Explanation:

Since we only have one strand shown, I'm going to assume it is RNA. Both DNA and RNA have nucleic acids, but RNA has 1 different nucleic acid; it replaces Thymine with Uracil. So the 4 nucleic acids are uracil, adenine, guanine, and cytosine.

If the picture shown is a cross-section of DNA, then our 4 nucleic acids are adenine, thymine, guanine, and cytosine.
