Answer: D. Our atmosphere is constantly being heated by the sun.
Radiation is the transmission of energy in the form of waves or particles released by one source and absorbed by another source. Types of radiations includes electromagnetic radiation, particle radiation, acoustic radiations and gravitational radiations.
Our atmosphere is constantly being heated by the sun is the example of the radiation because the sun radiates energy in all directions in the form of heat, light and radiations. Solar energy in the form of radiation is either reflected back to the sun or it is absorbed by the earth atmosphere. Therefore, this causes heating up of the earth atmosphere.
The answer would be b. in the nucleus DNA instructions are copied as RNA messages. This is called translation. The RNA then takes that information to the ribosome where it is transcribed into amino acids, which will form a polypeptide chain and create a protein! Hope this helped :)
Both use the scientific method to an extent and are a way of scientific exploration.
