The correct answer is It would be more difficult for DNA to unzip since it would require more energy to break the bonds.
That is because it would most probably be a covalent bond and such a bond is stronger than a hydrogen bond which means that more energy would be needed to break it.

Explanation:
Answer:
The correct answer will be option-B.
Explanation:
Photosystem of a plant is complex pigment-protein molecules which absorbs the light energy required for the formation of a glucose molecule.
Two types of Photosystem are present in the plants which are: P₆₈₀ and P₇₀₀. The 680 and 700 denote the wavelength of the light energy absorbed by the pigment of the chloroplast. The electrons get excited only at their absorbing wavelength.
Thus, Option-B is the correct answer.
<span>B. Bending of light decreases
</span>According to the law of reflection, it stated that when light strikes
the boundary between different media, a portion of the light is reflected while
another portion enters the medium. Thus, the process in which the ray of light
crosses the boundary and enters the second medium is known as refraction.
However, the velocity of light decreases when light enters a denser medium.
