Burning of fossilfuels and deforestation are the two actions that most likely lead to an increase of carbon dioxide levels in the atmosphere.
The decomposition of buried carbon-based organisms that died millions of years ago produces fossil fuels.
They produce carbon-rich deposits, which are extracted and burned to generate energy. They are nonrenewable and currently provide approximately 80% of the world's energy.
The photo with the smoke from the cars will increase the carbon dioxide in the atmosphere by directly adding carbon dioxide to the atmosphere (as well as other compounds such as sulfur and carbon monoxide).
Thus, the "switch off" photo reduces electricityconsumption, which, if done collectively, may reduce the burning of fossil fuels, lowering carbon dioxide levels in the atmosphere.

Your question seems incomplete, the probable missing part of the question is:
water evaporation.
c.
water precipitation.
b.
water condensation.
d.
the water cycle.
The correct answer is option option D
The movement of water from ocean to atmosphere, then land and back to the ocean. This whole process forms a cycle called as water cycle.
It assures the movement of water from land to sky and back from the sky to land. The water from the ocean and sea evaporates into the atmosphere and goes into the sky to form clouds.
These clouds causes rain (precipitation) which falls on the land and then the water flows back to the ocean.
This cycle is known as water cycle.
Answer:
mRNA (messenger RNA)
Explanation:
mRNA is transcribed from DNA (a process called transcription) where the mRNA acts as a blueprint to build proteins aka polypeptide formation.
