The diagram below represents the evolutionary history of the horse. Which best accounts for the changes in the horse?
Through artificial selection, larger horses survived and were chosen to reproduce
Through artificial selection, smaller horses were bred out of the gene pool, leaving only larger horses
Through natural selection, favorable adaptions were passed to offspring, allowing for the evolution of the horse
Through natural selection, horses acquired traits that produced changes and then were passed on to their offspring
What best describes mutualism?

A science teacher mixes calcium chloride and vinegar in a test tube. He passes the test tube around for his students to feel. The students notice that the test tube is hot. The science teacher asks the students to decide if the mixing of the two chemicals involved a physical or chemical change. He also asks the students to justify their answer. Which student gave the correct response?
Student 1: The change was physical because a temperature change occurred.
Student 2. The change was chemical because a temperature change occurred.
Student 3: The change was physical because the two chemicals mixed.
Student 4: The change was chemical because the two chemicals mixed.

It would cause increased dissolved oxygen.
It would cause increased water clarity.
It would cause extremely cold water.
