Rays having a wavelength greater than 400 nm (such as visible, infrared, radio waves, etc.) do not cause damage to the cell.
Ultraviolet (UV) radiation is electromagnetic radiation with a wavelength between 100 and 400 nm.
Ionizing radiation such as X and gamma rays also have a small wavelength (less than that of UV rays), and can penetrate the cell and cause damage to the cell.
Answer:
Because density is mass divided by volume and it will always stay the same for a certain substance while mass and volume will always vary.
Answer:
temperature before the increase in CO2 was a few degrees lower than temperature after the increase.
Explanation:
CO2 in the atmosphere has the property of trapping heat by absorbing it. So, with increase in the level of CO2 in the atmosphere the more heat will be absorbed by it and hence the temperature before the increase in CO2 was a few degrees lower than temperature after the increase.
Level of CO2 ∝ Temperature of the Earth
Answer:
Catalysts
Explanation:
Catalysts lower the aviation energy.
Answer:
15.9994 amu
Explanation:
By definition 1 mole of any substance is the mass that contains 1 Avogadro's Number of particle. (=> 6.02 x 10²³ particles/mole).
1 mole Oxy => 15.9994 amu => contains 6.02 x 10²³ particles Oxy /mole
1 mole Sulfur => 32.064 amu => contains 6.02 x 10²³ particles Sulfur /mole
1 mole H₂O => 18 amu => contains 6.02 x 10²³ molecules of water / mole.
