The correct answer is an accumulation of microorganisms in deep marine environments.
Chalk rock refers to a pure form of limestone produced in tropical and warm seas about 100 million years ago in the Cretaceous period. The microscopic marine algae known as coccoliths thrived in the ancient seas. Their shells were comprised of calcite. With the death of the algae, their bodies sunk to the floor of the sea and sediment of chalk got deposited.
Over many years layers of chalk sediment got deposited and resulted in compaction of loose sediment into solid chalk rock.

Explanation:
Photosynthesis and cellular respiration are related in that; photosynthesis is a process that is tasked in making glucose which is then used in cellular respiration to make ATP. The glucose is then converted to carbon dioxide during cellular respiration, which is used in photosynthesis. Water on the other hand is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Answer: The results will tell us about the correctness of hypothesis.
<u>Explanation:</u>
The Hypothesis is that explanation which is used as a starting of any investigation. The Hypothesis can or cannot be correct. We can test the hypothesis with scientific research.
Now a student can make conclusions about the hypothesis based on the results obtained. If results are the same as the hypothesis it means that our proposed explanation i.e hypothesis was correct but if the result differs than it means the hypothesis was not correct.
