Arteries are blood carrying vessels which have thick, elastic, muscular walls, have no valves and in which blood flows under high pressure. The make up of arteries is unique to their function of transporting blood under high pressure.
All arteries carry oxygenated blood from the heart to all other parts of the body, with the exception of the pulmonary artery which carries de-oxygenated blood from the heart to the lungs. It is the only artery that transports blood which has not been oxygenated.
This situation is the perfect example of the random process that is called genetic drift. A minor, usually, form of evolution that works best in small <span>populations or in situation as you have described above.
I hope you get this answer right!
Have a great day!:DDDD :)!</span>
<span>The organ that is home to alveoli, broncioles, and bronchi which are moist with mucus and line with cilia are the lungs. The lungs are used to bring oxygen into the body and carry it to the heart which in turn pumps it throughout the entire human body to all the other organs.</span>

None of those options are correct.
Fungi produce,naturally, antibiotics that will kill or inhibit the growth of bacteria.
This is useful for them to limit competition in their natural environment but it's also useful for us because it will kill bacteria that cause us infections.
The only thing scientists had to do is isolate that antibiotic.
Some antibiotics that were developed from fungi: penicillin and cephalosporins.
