Ascientist is studying two different kinds of the same species of fly that live around a lake. the scientist calls these two different kinds of flies type x and type y. both of these kinds of flies live near water and thrive in the same kinds of weather conditions. the two types of flies look similar, but type x flies are, on average, 20% larger than type y flies.

over a period of five years, deforestation occurred in an area about 50 km from the lake. this caused animals from these areas to move into wooded areas closer to the lake. the bar chart below shows data about the amount of deforestation that occurred in the nearby forest. the scientist collected population data on the flies. this data is shown in the graph below.

What evidence could be used to convince policy makers to change a shipping lane from going through a whale breeding ground? information on the number of all whale species currently alive information on the number of all whales hit by boats in the given area information on the number of whale deaths in the world's oceans information on the number of whale offspring born every year. (a) scientists could collect and combine data on fish populations all around the world to show that their populations are declining. (b) scientists collect and combine data on fish populations all around the world to show that their populations are increasing. (c) scientists work together and use past data to show that fish populations are becoming locally extinct in some areas. (d) scientists work together and use past data to show that some fish populations are adapting to environmental changes.
