When homeostasis is not maintained, the body cannot function properly and illness may ensure. Homeostasis is the process in which the body's overall internal environment is kept constant in response to any external environmental changes. This involves maintaining stability in different body systems.
<span>Natural selection is likely when there are stronger selection pressures. For example, a perpetual selection pressure is the fact that organisms have to compete for food and resources, meaning the best adapted ones survive. However, a stronger selection pressure may cause natural selection to occur more obviously. An example of this is when the number of white peppered moths decreased during industrialization in England due to the soot collecting on the trees. The change in population was very fast and obvious.</span>

Answer:
8 miles
Explanation:
Velocity is speed+direction (the speed of something in a given direction). We know that running on a track, one is moving forwards, which is why the velocity given as positive. Now we do some simple algebra. 120 minutes is equal to 2 hours. At a velocity of 4 miles an hour, for 2 hours, you multiply 4x2 and get 8, which is how far (in miles, units are important) the man has traveled once he comes to a stop.
