Answer:

Explanation:
The measure of R is always the same, but the numbers may differ depending on the units you use.
For example, in SI units, R = 8.314 Pa·m³K⁻¹mol
If your measurement uses different units, you must either convert your units to SI or use a value of R consistent with your units.
If you use bars and litres, R = 0.083 14 bar·L·K⁻¹mol⁻¹.
If you use kilopascals and litres, R = 8.314 kPa·L·K⁻¹mol
If you use atmospheres and litres, R = 0.082 06 L·atm·K⁻¹mol⁻¹.
If you use Torr and cubic centimetres, R = 62 368 Torr·cm³ K⁻¹mol⁻¹.
The only units that don't change are "K⁻¹mol⁻¹".

Answer:
The ideal gas equation
Explanation:
The ideal gas equation is derived from the combination of three gas laws:
- Boyle's law
- Charles's law
- Avogadro's law.
The ideal gas law is expressed mathematically as: PV=nRT where:
P is pressure
V is volume
n is the number of moles
R is the ideal gas law
T is temperature.
To obtain the combined gas law, we assume that n=1 and this gives:
= R
Therefore:
=

The question is incomplete as it does not have the options which are:
A) photosystem II
B) photosystem I
C) cyclic electron flow
D) linear electron flow
E) chlorophyll
Answer:Cyclic electron flow
Explanation:
The plants produce ATP molecule by the process of a light-dependent phase of photosynthesis which produces ATP and NADPH molecules.
The ATP and NADPH are produced by the non-cyclic flow of electrons called Z-scheme but when the plant needs extra ATP molecules, they produce more ATP by the cyclic electron flow.
The cyclic electron flow begins when the P₇₀₀ activates electron which then transferred to ferredoxin and then to cyt b₆f and then to plastocyanin. This is repeated and produce ATP molecules escaping the production of NADPH.
Thus, Cyclic electron flow is correct.
