Answer:
Antibiotic resistance occurs when bacteria do some variation in their genome that allows bacteria to eliminate the effect of antibacterial drugs. Irregular or excessive antibiotics use is the main cause of generating antibiotic resistance bacteria.
So antibiotics should be taken only on the prescription of doctors and a complete course of antibiotics should be done to eliminate all the bacteria so that no bacteria is left to generate antibiotic-resistant bacteria.
Antibiotics should be avoided in viral infection as antibiotic does not kill viruses as it is only beneficial in bacterial infection.
They have chloroplasts. They do not possess mobility because they cannot just stand up and walk to the nearest river. Unicellular organisms are very small, and most organisms are multi-cellular, including plants. Plants, animals, and fungi are eukaryotic, but only bacteria is prokaryotic. So therefore, choice 3 is correct.

Explanation:
Do not keep the tap running, when washing your hands.
Do not shower every day.
When showering, get in, shut the tap down. While still wet in the shower, but without the water running, start to apply soap and shampoo. Wait a bit and the start the water again to wash it all off. Get out asap.
Do not keep the hose running, when cleaning your car.
Preferably, do <em>not</em> use a hose, but use a broom, to clean the driveway or sidewalk.
Cover the swimming pool, in order to reduce extensive evaporation.
Check for leaks in pipes, hoses, (dripping) faucets and couplings.
If at all possible, reuse wastewater as much as you can.
The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.
The quantity and quality of DNA can be greatly improved by performing PCR.
* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.
The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
