The correct option is B. It regulates body temperature.
<h3>What is homeostasis?</h3>
In biology, homeostasis is the condition of steady internal, physical, and chemical requirements maintained by living systems.
- This is the requirement of optimal functioning for the organism and contains many variables, such as body temperature and fluid balance, being kept within certain pre-set limitations (homeostatic range).
- Other variables include the pH of extracellular fluid, the engagements of sodium, potassium, and calcium ions, as competently as the blood sugar level, and these need to be regulated despite changes in the atmosphere, diet, or level of activity. Each of these variables is controlled by one or better controllers or homeostatic mechanisms, which together maintain life.
- Homeostasis exist obtained about by a natural resistance to switch when already in the optimal conditions, and balance is maintained by many regulatory mechanisms.
- All homeostatic control mechanisms include at least three interdependent elements for the variable being regulated: a receptor, a control center, and an effector.

Semipermeable means something can be penetrated by a few things. that being said choices A and B can be eliminated.
Choice D would negate semi as it says all polar molecules, leaving choice C as the best answer
C. according to Earth's existing magnetic field.
It is important the entire scientific community uses the metric system rather than each country having its own system because when scientist are comparing or sharing results they wont have to do extra steps of converting to different measurements it will just be the same and less confusing.
