Answer:
Marine life is least affected by the temperature fluctuations of the atmosphere.
Explanation:
The high specific heat capacity of water means that it takes much more energy to raise the temperatures of water by one (1) degree than land. This means that on a hot sunny day, land temperatures would increase dramatically while ocean temperatures would only rise slightly. Conversely, at night, the land cools rapidly while oceans cool slowly hence the temperatures drop slightly.
Matter can only me transformed, but not created or destroyed.

Immunization shots are given to ensure immunity against future attacks on the body against the disease in which the vaccine is made.
Explanation:
The vaccine prepares the body by giving immune cells memory against the disease agent. The vaccine achieves this by introducing an attenuated form of the agent of the disease into the body. This means the introduced disease agents cannot cause disease but are enough to evoke an immune response from the body. The immune system, after eradicating the attenuated disease agent from the body, acquires memory such that it fights a real-world disease agent in case of infection.
