After the industrial revolution began, most of the peppered moths observed were dark in color. Why?

• Light-color moths were more fit for survival because they were less camouflaged against the darkened, soot-covered tree bark.

• Dark-color moths were more fit for survival because they were less camouflaged against the darkened, soot-covered tree bark.

• Dark-color moths were more fit for survival because they were more camouflaged against the darkened, soot-covered tree bark.

• Light-color moths were more fit for survival because they were more camouflaged against the darkened, soot-covered tree bark.

Large fishing nets that are over 50 meters are used to catch tons of fish from the oceans. What is an effect of these large fishing nets on non-target organisms?

• Many non-target organisms become endangered species because they get caught in the nets.

• The non-target organisms are unable to adapt when dumped back in the oceans.

• The non-target organisms migrate to freshwater ecosystems.

• Many non-target small organisms that escape the nets decrease in number.
