I think it’s the phenotypes
A, B, and C make no sense
A makes no sense because Methane is lighter than air, and so the Methane would stay higher in the atmosphere, so it would not seep into the ground, it would remain in the air.
B makes no sense because Burning fossil fuels causes air pollution by increasing the amount of carbon dioxide in the air. the only way that carbon dioxide could pollute water is if it is combined on a molecular level, plus carbon dioxide does not inhibit the process of water being evaporated by the sun.
C also makes no sense because Deforestation causes acid rain by increasing carbon dioxide not decreasing carbon dioxide in the atmosphere.
so therefore by elimination your answer is D
Then the model will become useless. originally the bottle should be air tight only tubes connected to the balloons, so that pressure can be shown when you adjust the plastic sheet in the bottom of the model. but now if there's a hole, air can move freely in or out the bottle and the model will not be able to show anything that occurs during respiration

Sedimentary rocks form layers. Thus, the correct option is A.
<h3>What are Sedimentary rocks?</h3>
Sedimentary rocks may be defined as a type of rocks that are created by the collection or deposition of mineral or organic particles on Earth's surface. After this, an activity of cementation is followed.
The layer of sedimentary rocks determined the age of fossils that are buried in those such layers.
Therefore, the correct option is A.
