Ateam led by evolutionary biologist hopi hoekstra set out to test the hypothesis that predators are an agent of natural selection on mouse color. they made 250 plasticine models of mice that were alike in every way except that half were painted white and half were painted brown. complete a paragraph about two advantages and one disadvantage of using model mice instead of real mice in this experiment.

Been sitting here trying to take this test and don't know this answer! place the events of a feedback mechanism associated with body temperature in the correct order. ·nerve cells send message from skin to the brain ·body returned to normal temperature around 98.6 degrees f ·temperatures regulation center in the brain sends out signals ·body temperature exceeds 98.6 degrees f ·sweat glands throughout the body activate to cool off skin surface it is a 1 through 5 question in biology!
