How do bacterial species build antibiotic resistance? Do viruses do the same thing?

When bacteria develop fortifications against the antibiotics that are developed to eradicate them it is termed as antibiotic resistance. Antimicrobial resistance is not only applicable to bacteria, but it is also applicable to other germs like fungi or viruses. There are various ways by which bacteria develop confrontation against antibiotics.  

Some bacteria are naturally resilient due to the nonexistence of the target that the antibiotic attacks or due to a remarkably impervious cell membrane. Some of the bacteria possess the tendency to generate enzymes, which can incapacitate antibiotics at the time of acquaintance. In some of the situations, bacteria can change the target of the antibiotics, making the antibiotic inefficient. The generation of efflux pumps in some of the bacteria makes antibiotics to get transport out of the bacterial cell.  

The antibiotics are not efficient against viral infections like influenza, colds, bronchitis, the majority of sore throats, and many ear infections and sinuses. The widespread application of antibiotics for these illnesses can generate the spread of antibiotic resistance.  

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
