All plants have chlorophyll-a which blocks(reflects) green light and absorbs red and blue wavelengths. It seems like it would be more efficient for plants to absorb green light since energy is most powerful from the sun through green wavelengths. However, the chlorophyll-a in chloroplasts actually defend the plant from harmful damage of the TREMENDOUS amount of power from the sun transmitted in green wavelengths.
SO CHLOROPHYLL-A PROTECTS PLANTS FROM TOO MUCH ENERGY IN GREEN LIGHT.
The fossilized fish which is found has jaws but no true bones belonging at point B on the Cladogram. Thus, the correct option is B.
<h3>What is Cladogram?</h3>
A cladogram may be defined as a phylogenetic tree that is based on the classification of evolutionary relationships.
In the given cladogram, D is any ancestral point from which speciation occurs. Point C is a basal taxon while A and B are sister taxons.
The organisms of point B have only jaws bu,t not true bones, while the organisms at point A have both jaws and true bones.
Therefore, it is well described above.

Mucilaginous sheath. Cyanobacteria are microorganisms that have survived for a thousand years now. They process and create their food through the photosynthetic mechanisms they possess and this process also includes nitrogen fixation and other biogeochemical process that contributes to most cycles.
