alex41 [277]

Answer:

E-----> C------>D------->A------->B

Explanation:

The cerebrospinal fluid (CSF) is the fluid of the central nervous system. It allows for buoyancy as the brain is immersed in the fluid, protection, excretion of waste products from the brain and many more. The production of CSF is by the CHORIOD PLEXUS  in the lateral, third and fourth ventricles. The CSF flows through the interventricular foramen from the lateral to the third ventricle and from the third ventricle into the fourth ventricle through the cerebral aqueduct which connects them. The CSF then flows into the subarachnoid space. Absorption of CSF into the blood is by the arachnoid villi and then the CSF enters the blood.

What is the most likely explanation for the results in the graph?
Delicious77 [7]

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.
