Answer:

Option B

Explanation:

Answer A is incorrect as the data is not analyzing how many fish each lake has, but rather the pelvic score of the fish. Answer C is incorrect as the graph shows that the fish in Frog Lake are complete, and that there are 0 fish that have reduced or absent pelvic scores, therefore the fish don't have varying pelvic structures. Answer D is incorrect because the data is not analyzing the size of the fish and again is only analyzing the pelvic score of the fish. This being said by process of elimination the answer would be option B, as the fish in Bear Paw Lack lack complete pelvic spines but rather have reduced or absent pelvic spines.

Which is not a likely economic tool to address environmental issues?
Elden [556K]

Explanation:

Policy-makers have two broad types of instruments available for changing consumption and production habits in society. They can use traditional regulatory approaches (sometimes referred to as command-and-control approaches) that set specific standards across polluters, or they can use economic incentive or market-based policies that rely on market forces to correct for producer and consumer behavior. Incentives are extensively discussed in several EPA reports

Two basic types of traditional regulatory approaches exist. The first, a technology or design standard, mandates specific control technologies or production processes that polluters must use to meet an emissions standard. The second, a performance-based standard, also requires that polluters meet an emissions standard, but allows the polluters to choose any available method to meet that standard. Performance-based standards that are technology-based, for example, do not specify a particular technology, but rather consider what available and affordable technologies can achieve when establishing a limit on emissions. At times, EPA may completely ban or phase out the use or production of a particular product or pollutant, as it has done with chlorofluorocarbons (CFCs) and certain pesticides. Regulations can be uniform or can vary according to size of the polluting entity, production processes, or similar factors. Regulations are often tailored in this manner so that similar regulated entities are treated equally. MARK AS BRAINLIEST IF IT HELPS
