P680 is said to be the strongest biological oxidizing agent. The strong oxidizing potential of P680 is essential for its function because it . obtains electrons from the oxygen atom in a water molecule is the receptor for the most excited electron in either photosystem of photosynthesis transfers its electrons to reduce NADP to NADPH is the molecule that transfers electrons to plastoquinone (Pq) of the electron transfer system

explanation:

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

the cell is the smallest structural and functional unit of living organisms, which can exist on its own. therefore, it is sometimes called the building block of life. some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
