If the alcohol concentration in PEA agar was increased, it would inhibit both Gram - and Gram + bacteria by breaking down membrane absorbency barrier, tolerating influx of substances that are generally blocked and leakage of cellular potassium. High alcohol concentrations would lead to disruption or halting of DNA synthesis in both Gram + and Gram - bacteria
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.
Answer:
Explanation:
Electromagnetic waves all travel at the speed of light when in vacuum, and essentially this same speed in normal air. Since wave speed is product of frequency and wavelength, c = f λ and λ = c/f = (3.00 x 108 m/s) / (7.5 x 1014 Hz) = 4.00 x 10-7 m = 400 x 10-9 m = 400 nm.

Well if it could not adapt it would die. Either it would be killed by a more superior species, natural selection would take its course, or it just wouldn't be able to survive.
