which of the following is true concerning hull fouling from commercial shipping and recreational boating?\na. it constitutes less than half of all nonnative species introductions.\nb. the revenue brought in from these industries is relatively small.\nc. it is difficult to prevent since ship hulls begin, conduct, and end voyages in water.\nd. it is best combated by chemical treatments.

Answer

Brief Explanations:

Hull fouling occurs as ships travel through water, and since ship hulls are constantly in contact with water during voyages, it's hard to prevent. Non - native species can attach to hulls easily during these water - based activities. Chemical treatments have environmental drawbacks and hull fouling contributes to a significant portion of non - native species introductions. Revenue is not related to the nature of hull fouling prevention.

Answer:

C. It is difficult to prevent since ship hulls begin, conduct, and end voyages in water.
