resistance
its one of these (only one of them is correct but i dont know which one): -viral infections -binary fission -bacterial resistance -fungal infections AGAIN,I DONT KNOW WHICH ONE IS THE RIGHT ANSWER . ASK ANYONE IF POSSIBLE.
One similarity is that both antibiotics and disinfectants help keep people healthy. The difference is antibiotics inhibit or kill microorganisms while disinfectants only kill them.
Not usually. Since colds are caused by viruses, taking an antibiotic at the first sign of a cold is useless and is an overuse of those drugs - which also leads to ineffectiveness of those drugs. People who have colds and/or flu can develop secondary infections which can be treated with antibiotics. But using antibiotics as a preventive is not considered responsible medicine when it comes to colds.
When they're actually used correctly, antibiotics can do an amazing job of clearing up the most lethal bacterial infections. And if you're sick enough to be hospitalized for an infectious illness like pneumonia, those antibiotics might even save your life. But like most drugs today, antibiotics are overused and over- prescribed-despite repeated pleas from infectious disease experts warning otherwise. Their crystal clear usage guidelines are often ignored by busy doctors eager to appease the many patients who show up demanding a quick fix for their colds and sore throats. One of the most serious problems with antibiotic overuse is that too many strains of bacteria are becoming resistant to the drugs.
The number one concern is Obesity.
The vast majority of "colds" are due to viruses, with the rhinovirus being one of the most common. Antibiotics help fight bacterial infections, but don't work against viruses. Also, overuse of antibiotics just leads to more resistant strains of bacteria. Get good rest, plenty of fluids, vitamin C, zinc lozenges, and tissues.

One thing that kills Steptococcus is antibiotics, which is why doctors prescribe antibiotics when you have strep throat.
Antibiotics are substances which, in high dilution, either prevent bacteria form growing or destroy bacteria. They are becoming less effective because widespread use of antibiotics is selecting those bacteria which have abilities to survive the affects of the antibiotics. In effect we are seeing evolution in action.
one concern is, that many pesticides are killing multiple insects
Penicillin is just one, but there are a lot more. Their uses depend on particular bacterial species and antibiotics resistance.
