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.
Answer:
Creating a model provides a practical solution for some scientific research by showing systems that are very large,small,or complex.Models are simplified representations of real objects or systems.Models can make things easier to study by zooming in on a single piece of a large system or magnifying something that is too tiny to see with the naked eye.

Answer:
B. Stored energy decreases from Consumer 2 to
Consumer 3.
Explanation:
As energy is transferred from one trophic level to another on the pyramid, the amount of stored energy available for those above a trophic level decreases.
The greatest amount of energy is found at the bottom of the pyramid, where we have the producers.
Consumers at the top of the pyramid have the least amount of stored energy.
The statement that is correct about the pyramid is: "B. Stored energy decreases from Consumer 2 to
Consumer 3."
Answer:
A frog's pelvis(hip bones) can slide up and down its spine, which may help it jump. The vertebrae at the bottom end of the spine are fused into one bone called the urostyle much like our coccyx(tailbone) - the remains of their tadpole tail.
