Answer:
64
Explanation:
Nitrogen combines directly with oxygen at very high temperatures to form nitrogen(ii) oxide. This is the reaction that occurs during lightning flashes. Atmospheric nitrogen and oxygen combines during the high temperatures obtained in lightning flashes to form nitrogen (ii) oxide.
Equation of the reaction is given below:
N(g) + O(g) ---> 2NO(g)
From the equation of the reaction, 1 mole of nitrogen gas combines with one mole of oxygen gas to produce 2 moles of nitrogen (ii) oxide.
Therefore, 2 moles of oxygen gas will react with 2 moles of nitrogen gas
Mass of oxygen gas that is 2 moles of the gas is obtained from the formula; mass = number of moles * molar mass
Molar mass of oxygen gas = 32.0 g/mol
Mass of 2 moles of oxygen gas = 2 * 32.0 = 56 g
Therefore, the mass of oxygen required in grams is 64
Protein phosphates have the opposite effect as protein kinases. They dephosphorylate proteins. An example is the Protein phosphatase 1 that is significant to transcription regulation in the cell nucleus. If Protein phosphatases are not working, the cells would be unable to respond to environmental stimuli and would die.
Answer:
Cells that need to perform high amounts of work, such as muscle cells in the heart and legs, fat cells and liver cells. Mitochondria are organelles which contain their own DNA. Animal cells generally have approximately 1,000 to 2,000 mitochondria.

Explanation:
Many of these diseases can be prevented by the use of viral vaccines, which stimulate protective immunity against the virus without causing major disease. Viral vaccines may also be used in active viral infections, boosting the ability of the immune system to control or destroy the virus.
