Answer: A) NO increases the rate at which 
molecules are formed.
Explanation:
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more reactant molecules can cross the energy barrier by undergoing collisions and convert to products.
Thus NO will increase the rate of reaction by lowering the activation energy and thus the colllisions among 
and 
molecules will incraese which in turn will lead to formatioon of more molecules.
Answer:
C. a computer
Explanation:
Quantitative data are measures of values or counts and are expressed as numbers. The best tool out of all shown to deal with a large amount of numerical data is a computer
Answer:
Inspiration
Explanation:
This question is on application of Boyle's law; <u>pressure is inversely proportional to volume</u>.when we inhale air, the diaphragm and the muscles in the ribs contract thus increasing the volume in the lungs.Increased volume of the lungs cause the pressure to decrease.During exhaling, the diaphragm and muscles in the ribs relax, making the lungs to recoil and reduce in volume to force air out.Pressure in the lungs is increased than that in the environment making air to move out.
Answer:
It is involved in the conversion of ADP to ATP
Explanation:
Most enzymes in biological systems function by reversible uptake and release of hydrogen in redox processes. The enzyme that catalyses the conversion of ADP to ATP also works by hydrogen ion transfer. Hence H+ is required in photosynthesis for the conversion of ADP to ATP
