- Make sure taps and such have no leaks.
- Keep a bucket underneath taps and use the water saved in them for gardening.
- Avoid flushing the toilet when unnecessary ("If it's yellow let it mellow, if it's brown flush it down"). And avoid throwing tissues in the toilets, instead throw in a proper bin.
- Never put water down the drain when there may be another use for it such as cleaning or watering a plant or garden.
- Water lawns during the early morning hours when temperatures and wind speed are the lowest. This reduces loss from evaporation.

<span>During transcription, a DNA template is used for production of a messenger RNA, by the action of enzyme RNA polymerase. Following this, the mRNA is sed for synthesis of the proteins, by the process of translation. Whole mechansim is known as central dogma.</span>
Answer: The correct answer is nucleotide.
Explanation:
Nucleic acids are the polymer of nucleotides which are attached with each other with the help of phospho-diester bonds.
Nucleotide consists of sugar (ribose in RNA and deoxyribose in DNA), phosphate group, and nitrogenous base (A, T, G, and in DNA; and A, U, G, and C in RNA).
Answer:
The answer would be A.
Explanation:
In mRNA sequence, the base T will be replace by base U. So in this case, DNA sequence is AATGCTCAG, then mRNA sequence is AA<u>U</u>GC<u>U</u>CAG.
Answer:
Wind
Tides
Geothermal energy
Explanation:
1. Wind does not contaminate and is inexhaustible.
2. Tides are due to gravitational interaction with the Moon and Sun and the Earth's rotation, so it is classified as inexhaustible.
3. Geothermal energy is renewable because heat is continuously being produced inside the Earth, at the core.
