This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.
Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.
Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.
These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).

Answer:
Yes
Explanation:
Because scientists have discovered waves that rise up to be taller than some sky scrapers. However, rather than being found on sunny beaches in exotic locations around the world, these waves are three miles beneath the surface of the ocean.
Answer: Temperature on monday morning is 319,5K
Explanation: This is an example of Gay Lussac law on gases which states that at constant volume, pressure and temperature are directly related, so if one raises the other one does as well.
The equation that follow the law is :
P1 / T1 = P2/T2 where 1 is the initial pressure and temperature and 2 is the final state.
In this equation, values have to be expressed in atm for pressure and Kelvin for temperature.
The missing value is T2 (monday temperature), so we have to clear it from the equation
T2 =P2.T1/P1
Replacing values:
T2 = 1,073 atm . 338K /1,135 atm
T2 = 319,5 K
The answer is A is you agree no problem im here to help if you disagree its ok i tried my best to help just saying
