In humans, the antibiotic amoxicillin (a type of penicillin) is used to treat certain bacterial infections. Complete the sentenc
mihalych1998 [28]

Answer:

Amoxicillin inhibits an enzyme required to build cell walls in bacteria.

Since humans have cell membranes, they are unaffected by amoxicillin.

Explanation:

Antibiotics are specifically designed to target bacterial cells, therefore, they don't kill human cells.

Amoxicillin, a type of penicillin, inhibits the biosynthesis of bacterial cell wall. The bacterial cell wall contains peptidoglycan that constitutes almost 95% of the cell wall in some Gram positive bacteria and as little as 5-10% of the cell wall in Gram negative bacteria. Amoxicillin inhibits the cross linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram positive and Gram negative bacteria.

Which of the following statements related to energy conversion and generation of x-rays is correct?
pishuonlain [190]

Answer:

The answer is D.

Explanation:

The way x-rays are produced is as follows; using a vacuum environment in a tube, the cathode is heated to a degree where it releases electrons, then these electrons collide with the anode releasing energy that create the x-rays.

All of the options are correct. Although the electron most likely won't stop, it will slow down and change direction after the collision. The law of conservation of energy is also applied in this situation, meaning that the kinetic energy of the electron released by the cathode will transfer to the anode to produce the x-rays. Most of the energy after the collision is converted into heat, which is why the metal used as the anode can heat up to 2000 degrees celcius.

I hope this answer helps.
