A valence electron is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom.
Option A.
The answer is the conversion of ADP to ATP using light energy. Photophosphorylation occurs in the light stage of photosynthesis. There are two types of photophosphorylation; cyclic and non-cyclic. In cyclic (which occurs only in bacteria), only photosystem I is utilized in the process while in non-cyclic, both photosystems I and II are used. In non-cyclic photophosphorylation, in addition to ATP, NADH is also synthesized.
Answer:
The correct answer is c. Bacteremia
Explanation:
Nosocomial infection is a hospital-acquired infection. Intravenous catheterization is majorly used in hospitals for therapeutic purposes like drug administration, blood sampling, etc.
These catheters are one of the major causes of nosocomial bacteremia in patients. Bacteremia is the condition in which bacteria is present in the blood.
So these catheter can be contaminated with bacteria which came from a patient and when they are used in another patient without proper sterilization they can transfer these bacteria to other patients blood which then cause nosocomial bacteremia.
