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:
Explanation:
(A) PaO₂ below normal: PaO₂ is used to describe the partial pressure of oxygen dissolved in the blood. When it is below normal, it indicates the individual isn't getting enough oxygen hence there is low pressure of dissolved oxygen in the blood. This sign/symptom falls under the Respiratory/oxygenation data cluster.
(B) Dyspnea on exertion: Dyspnea is a term used to describe shortness of breath while dyspnea on exertion is when an individual runs out of breath as a result of not been able to breath deeply/properly during or after an exercise. This sign/symptom also falls under the Respiration/oxygenation data cluster.
(C) Productive cough: This is a type of cough that produces/forces mucus out of the airway (thereby clearing the airway). This sign/symptom from this description is also Respiratory/oxygenation data cluster.
(D) Oxygenation saturation 92%: Oxygen saturation is when the body can supply enough oxygen to the cells and tissues within it's system. This sign/symptom is also a Respiratory/oxygenation data cluster.
(E) Feels "too tired to do much": This can also be referred to as fatigue. This is usually as a result of inadequate energy produced (usually from glycolysis) in the body. This sign/symptom, from this description, is a Reduced energy level data cluster.
(F) Requires frequent rest periods: This usually occurs as a result of imbalance in the body's metabolism. Here, the body uses more energy than it produces; more anabolic processes (energy requiring) than catabolic processes (energy produced/released). This sign/symptom, from this description, is a Reduced energy level data cluster.
The cellular organization relates with one another since the colossal cell, the organ system is fundamentally composed of cells. Cells are the building blocks of these structures and which creates such organ and organ system. They associate as one cell intercommunicates with another cell until all received the message and translates it and sends it with another organ and to cell -vice-versa. And also, they become interdependent with the other cell -other tissue -other organs -other organ system.
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole. Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis.This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. How? Through cell division called, mitosis. Excerptmeiosis –cell division specifically in the sex cells.<span> </span>
Oxygen because lipids are fats that need oxygen to use long term energy
