Answer:
He discovered Propane gas
The visible spectrum of FD&C Blue 1 peaks in the 580-750 nm range. The optimum wavelength for measuring the absorbance versus concentration for FD&C Blue 1 is determined from the wavelength of maximum absorbance or lambda max, which has a value of 630 nm.
Phosphorus is, therefore important in cell division and development of new tissue.
It is also associated with complex energy transformations in the plant. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity.
Hopefully this helps :)
Answer:
Carbon assimilation is directly proportional to oxygen production.
Explanation:
Carbon is assimilated in form of carbon dioxide in plants during photosynthesis. iI diffuses through the stomata to the intercellular spaces of the leaves. An increase in carbon absorption increases the amount of oxygen produced into the atmosphere since oxygen is a by-product of photosynthesis.
Answer:
B. Two racehorses with desirable traits are bred to produce a superior racing horse.
Explanation:
Artificial selection is also called selective breeding. In artificial selection, two organisms having desirable characters are allowed to breed with each other in order to produce a specie having good characteristics or better from their parents in many ways. For example, two racehorses which contains desirable traits are allowed to breed to produce a better horse.
