Homeostasis is how the body functions to remain working perfectly. The body tries to maintain equilibrium and through all of the body's organs working together, homeostasis is achieved. For example, when you run your body exerts sweat. Sweating is your body maintaining homeostasis. Your body temperature is getting to high, so your body cools you off by releasing sweat. The answer in this case would be "a process by which organisms keep internal conditions relatively constant despite changes in external conditions"
Answer: It really depends on if the water solution is hypotonic, hypertonic, or isotonic. If it is hypotonic (water with less salt or other dissolvent in it than the cell), you can expect the cell to take in water and expand. If the water is isotonic (about the same amount of dissolvent in it as the cell) just about nothing will happen, or if the water is hypertonic (more dissolvent in the water than the cell) the water can seep out of the cell, and into the water.
Answer:
Changes in allele frequencies over time can indicate that genetic drift is occurring or that new mutations have been introduced into the population.
A snowy enviroment. such as a snow fox with white fur surviving better than a snow fox with brown fur. thus white fur fox decrease genetic diversity because it is more sucessful at surviving and reproducing than the brown fur fox
