Answer:
Explanation:
Photosystems are structural and functional
units of protein complexes that are involved in photosynthesis and carry out the absorption of light and transfer of electrons and energy. The reaction centers of photosystems are made up of structurally different pigments which enables plants absorb light energy at different wavelengths.

Answer:
It could happen through mutation
Explanation:
<em>A segment of DNA after many cell divisions could have more base pairs than it originally did as a result of mutation.</em>
Mutation is generally defined as a sudden change to the DNA sequence of a cell. This change could be of difference forms, including:
- <em>Addition of bases</em>
- <em>Deletion of bases</em>
- <em>Substitution of bases</em>
<u>Addition of bases to a DNA will generally lead to a longer base pairs in the DNA, deletion will lead to a shorter base pairs while substitution will only lead to a change in the base sequence without any change in the length of the DNA.</u>
The answer is all of the above
