The right answer is to perform photosynthesis (more precisely to convert ADP to ATP by ATP synthase).
Light comes to us in the form of photons. These photons have a different energy potential depending on their wavelength.
When a pigment picks up a photon corresponding to its absorption capacity, one of its electrons goes into the excited state. This energy can be transmitted in 3 ways: either by spreading it in the form of photon or heat; both ways lose energy. The third is to transmit resonance energy and there is almost no loss of energy.
A photosystem consists of a reaction center and a collector antenna to optimize the absorption of photons triggering photochemical reactions in order to operate the ATP synthase to produce ATP in the presence of a hydrogen gradient.
B it's a vegstigial trait
Many biology texts today still refer to the appendix as a vestigial organ
The answer to this is C because humans don't have cell walls and if you are looking at an onion it has a cell wall because it is a plant.
Thought and action are the two main functions
