The human body has three line of defenses to protect the body from the attack of the pathogens. The first line of defense includes the physical barriers that prevent the entry of these antigens into the body. The second line of defense includes the leukocytes, inflammatory response and fever, and the third line of defense includes the antibodies secreted by the lymphocytes and the memory cells.

The innate immunity includes the proteins and cells which are already present in the body of a person. The adaptive immunity fights the pathogens that escape the innate immunity. The components of adaptive immunity includes B and T lymphocytes. The acquired immunity refers to the memory of the previously fought antigen.

The fever and flu of the Nina exhibits the second line of defense which is a part of the innate immunity.

Answer:

The high transmittance (low absorption) reading indicates that chlorophyll absorbs very little green light.

The low transmittance (high absorption) reading indicates that chlorophyll absorbs most blue light

Explanation:

The galvanometer is a device which is used for measuring the electric current.
In a spectrophotometer the galvanometer is attached to indicated the amount of light that is getting transmitted through a sample.
If the amount of light that is getting transmitted from the sample is more, the reading of the galvanometer would be higher and if less light is transmitted the reading of the galvanometer would be less.
Further, the transmittance of a light is inversely proportional to the absorption, that is if the absorption would be low transmittance would be high and vice versa.
Therefore, when the chlorophyll is exposed to green light, the transmittance is high and this implies that the absorption of green light would be less.
Similarly, when the chlorophyll is exposed to blue light, a low transmittance indicates a higher absorption of blue light by chlorophyll.
