The most common transfusion reaction, especially in patients lacking either IgA especially serum IgA, is the development of potentially severe hypersensitivity reactions or anaphylaxis. The most probable culprit is the presence of IgA in the transfused blood, because since the individual lacks IgA, then the IgA in the transfused blood is considered a foreign body triggering an allergic response.
Answer:
Luminosity is an intrinsic(natural) measurable property of a star independent of distance. The concept of magnitude, on the other hand, incorporates distance. The apparent magnitude is a measure of the diminishing(decrease) flux of light as a result of distance according to the inverse-square law.
There must be a balance between the flow of energy into the atmosphere and the flow of energy out of the atmosphere and back to space.<span>After being warmed by incoming solar radiation throughout the day, the Earth emits infrared radiation, which is trapped near the Earth’s surface by carbon dioxide.This radiation is called thermal radiation.</span>
The correct option is C.
In chemistry, a radical is defined as an atom, ion or molecule that possess an unpaired valence electron. Generally, radicals are highly reactive chemically. Examples of radicals are hydroxyl, hypochlorite, nitrate, carbonate, oxalate, permanganate, etc. Free radicals combine with one another or with single atoms to produce neutral substances. In the question given above, the two compounds given in option C have the same type of radical, which is hydroxyl radical.
