In the z-scheme, water is the initial electron donor and NADP+ is the final electron acceptor.
<u>Explanation:
</u>
It is a process of photosynthesis. It occurs in photosynthetic chemical reaction. The z scheme is basically a term for representing the oxidation and reduction reaction occurring in plants during photosynthesis.
The water present in the chlorophyll pigment donates electrons and become the initial electron donor. Those electrons get transferred to NADP+ and forms NADPH. Thus, water acts as electron donor initially and so the final electron is NADP+.

A constellation is a group of stars in the sky.
If the group seems to form a pattern, or resemble anything,
it really has nothing to do with the constellation. The human
brain has evolved to seek and find patterns in what we see,
a habit of mind that turns out to have great survival value.
There's nothing "wrong" with seeing a pattern there. It's
a very natural, very human thing to do. But understand ...
the stars are not forming anything or doing anything. The
scorpion, the might hunter, the dog, the fish, the dragon,
the queen on her throne, the patterns ... are all in your mind.
Answer:
Because the mass of electrons and protons is very small
Explanation:
The gravitational force exerted between two objects is given by:
where
is the gravitational constant
m1 and m2 are the masses of the two objects
r is the distance between the two objects
The mass of a proton and of an electron is very small, so the gravitational force involved in case of such particles is very weak. Let's calculate for example the gravitational attraction between one proton and one electron at a distance of r = 1 m. We have:
- Proton mass:
- Electron mass:
So, the gravitational force between the two particles is:
Which is a very weak force.
By comparison, let's calculate instead the electromagnetic force between a proton and an electron (both having a charge of ) still separated by a distance of r = 1 m. We have:
Which we see is much stronger than the gravitational force (almost by a factor
Answer:
A lens
Explanation:
A lens forms images when light passes Through it bending the rays of in the process.A phenomena called refraction and the speed of light changes in the process because it enters a medium since it's wavelength is reduced.
