When calibrating a spectrophotometer, measuring absorbance concurrently is the best option for a blank since it is proportional to the concentration.
Beer's law states that A = a b c, wherein there is the diffusion coefficient at a constant, b is the actual route length, & c is the concentration. Direct proportionality exists between b and c and absorbance.
Once the route length is doubled, incident light contacts double as many molecules in the solution. The consequence is a doubling of absorbance, which is equivalent to a doubling of molecule concentration.
There are two ways to detect chemicals using spectrum scanning. One approach involves turning the monochromator continuously with a stepping motor while gradually altering the wavelength connected to the output slit.
It is more practical to use diode array detectors. Up to a few hundred photodiodes may be incorporated into the chip that makes up this device.

Answer:This states that the rate of a physiological process will be limited by the factor which is in shortest supply. Any change in the level of a limiting factor will affect the rate of reaction. For example, the amount of light will affect the rate of photosynthesis. If there is no light, there will be no photosynthesis.
Explanation:
Answer:
Partial nitrate reduction results in the formation of nitrite and water
Explanation:
Answer:
Deep and rapid.
Explanation:
Respiration may be defined as the process of exchange of gases between the atmosphere, alveoli and body tissue. Two important process of respiration are inspiration and expiration.
Aspirin drug may also effect the rate of respiration in the individual. The breathing rate get increased after taking the excess dose of aspirin. The increase in the breathing rate results in the rapid and deep breathing of the individual.
Thus, the correct answer is option (b).
