What evidence was provided to support this coevolution theory of the same gene mutation in populations so distant from each other? 13. Explain the selective advantage […]

DDT is also toxic to fish and aquatic invertebrates. Based on what you know about ecosystems and food chain dynamics, what are some potential impacts to an aquatic ecosystem that receives a particularly high dose of DDT (i.e., a much higher original concentration of DDT in the water)?

REFLECTION PROMPT: Choose two of the major tissue types. In yo–ur own w-ords, wri-te a short paragraph for each of your chosen tissue types reflecting on the relationship between structure and function in that tissue.
