A frog gets rid of it's urine through the kidneys because the heart pumps blood throughout the body, the lungs are used to take in O2 molecules and gills are use to filter out the hydrogen in HO2 so they can breathe under water. However the kidneys are part of the waste disposal system (what makes us need trip to the bathroom ever now and then) therefore that is the answer.<span />
This is an example of negative feedback.
After a big meal, glucose levels in the bloodstream increases. The body recognises this change and goes through homeostasis, or the regulation of bodily state or internal environment.
The pancreas secretes insulin, which then binds to insulin receptors. This will result in the uptake of excess glucose from the bloodstream into cells and converted into glycogen to be stored in cells as energy storage molecules.
Since there is the counter effect of body (i.e. when blood-glucose concentration increases, the body sends a signal to decrease the blood-glucose concentration, this is called a negative feedback (instead of a positive feedback, which occurs if for e.g. the body signals cells to increase blood-glucose concentration even after blood-glucose concentration increased after a heavy meal).
Hope this helps! :)

Answer:
2. What must be done to carbon dioxide gas to change it to a solid?.
Carbon dioxide is a gas by using a metal to solidify it
3. Which is colder, dry ice or carbon dioxide gas?
Carbondioxide gas
If dry ice is placed in water, we see bubbles rise.
4. These bubbles are made of
gaseous substance in the gaseous state.
5. What happens to the size of the dry ice as the bubbling goes on?
the size of the dry ice reduces as a result of conversion of solid to liquid form
