Answer:
Option A, it is more rapid than the primary response and results in higher antibody levels.
Explanation:
When an antigen contacts the immunity system for the first time it leads to a primary immune response. Since it is the first interaction, it requires more time to produce effect.
While a secondary response occurs when the same antigen attacks the same person second , third or n number of times. During secondary response, the body already has a memory of primary immune response and thus it is faster.
Hence, option A is correct

Answer:
True
Explanation:
Earth's radiation, that is, the energy that comes from the reflection, absorption, storage, and distribution from the Sun among the spheres play a major role in the climate systems.
The ultraviolet and visible energies from the Sun are the main drivers of the Earth's climate systems as the interaction between the particles of aerosol that are present in the atmosphere and the radiation from the Sun lead to the warming of the atmosphere.
Therefore, the answer is True.
