Final answer:
To combine the sentences into one sentence, use the coordinating conjunction 'and' to connect the phrases and convey their relatedness.
Step-by-step explanation:
To combine the sentences into one sentence, you can use a coordinating conjunction like 'and' or a subordinating conjunction like 'as'. Since the two sentences are related to each other and provide additional information, you can use the coordinating conjunction 'and' to combine them. So, the combined sentence would be: The sense of danger grows and the pheasants' vulnerability to hunters is revealed.
