Answer:
The correct answer is option a. "scales".
Explanation:
The missing information of this question is the following:
"Terry catches a ray-finned fish from the ocean and notices that attached to its flank is an equally long, snakelike organism. The attached organism has no external segmentation, no scales, a round mouth surrounded by a s*cker, and two small eyes. Terry concludes it is a hagfish."
Gymnophiona is a group of amphibians characterized by having dermal scales as integumentary element. These amphibians are tetrapods and their scales are comprised of several layers of unmineralized collagenous fibers. The skeleton of the hagfish is made entirely of cartilage, therefore it is very likely that the tooth-like objects of hagfish's are made of cartilage, just like the scales of the tetrapod.

Solutions are usually classified as either basic or acidic based on their hydrogen ion concentration.
Answer:
B. The apple orchard releases toxic chemicals into the water of the bay.
Explanation:
Option B is the correct answer. It is the most likely explanation for the results in the graph.
From the graph, we can see that the population of the fishes sharply dropped. Since the fertilizer is applied to the apple orchard and the orchard was planted beside the bay, during the rain it is possible that the water has washed some of the fertilizers into the bay. The chemicals used in making fertilizer are harmful and toxic.
This reveals that the toxic chemicals released from the apple orchard are responsible for the decline in the population of the fish.
