Increasing the surface area is your answer. I just took the same test with that same question.
Answer:
Although they receive a bad rap from the media and pharmaceuticals, the majority of prokaryotes are either harmless or actually help eukaryotes, such as animals and plants, to survive and only a small number of species are responsible for serious illnesses.
Explanation:
Answer:
Aquatic plants have aur filled tissues to make them easy to float.....
Explanation:
It provides buoyancy
The location where the mercury level of the barometer would be the lowest is at the very high altitudes of the Earth's atmosphere (about 100 km), since air pressure decreases as altitude increases. Hope my answer has come to your help.
Answer:
1 that is 100%
Explanation:
here it is given that Fermi energy of the of the metal = 5 e.V
work function= 4 e.V
we have to find the probability that an incident electron will tunnel out if E=109 V/m
WORK FUNCTION : work function is defined as the energy required to withdraw an electron completely from the metal surface.
now the energy per unit volume in electric field is given by
E=
E=
E=
in electron volt E=4.427\times 10^{6}joule × 6.24\times 10^{18}
E=
hence the applied energy per unit volume is greater than the work work function of electron so there is probability of 100% that electron will tunnel out
