Why are antibiotics for treating the common cold ? a. colds are cause by antibiotics b. colds are caused by bacteria c. antibiotics cannot treat illnesses d. virsus are not killed by antibiotics

The right option is; D. Virus are not killed by antibiotics

Antibiotics are unhelpful for treating the common cold because virus are not killed by antibiotics.

Antibiotics are medications that can destroy or inhibit the growth of bacteria. Antibiotics are only used for infections caused by bacteria. Antibiotics do not kill or work on viruses, such as the virus that cause common cold. This is because antibiotics destroy bacteria by directly aiming at its growth machinery but viruses reproduce differently and have different structures. Hence, viruses are not affected by antibiotics.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
