Density and distribution of stars are directly affected when the change occur in the size of the circle.
<h3>Effect on density </h3>
The density and distribution of "stars" changed as the circle gets larger because when the circle gets larger, its volume increase which results in the decrease in the density. The distribution of stars also changed due to more space or volume present in the medium.
<h3>Distribution</h3>
If the universe is more condensed, then the stars are more closer together but when the universe is more expand then the stars are present farther away from each other so we can conclude that density and distribution of stars are directly affected when the change occur in the size of the circle.

Answer:
Carbondioxide gas is responsible for global warming and climate change.
Explanation:
The climate change mostly occur due to increase in the concentration of carbondioxide gas in the atmosphere. The CFCs gases causes depletion of ozone layer in the atmosphere which is responsible for prevention of ultraviolet rays coming to the earth. The burning of fossil fuels in the vehicles and industries produces huge amount of carbondioxide gas that is released in the atmosphere that allows the sunlight to the earth but block its way after reflection which remain suspended in the lower surface causes increase in temperature which leads to global warming.
The answer is D. Breathing.
