Answer:
Minivalves
Explanation:
Lymphatic capillaries are so much permeable that some researchers thought that they are open from one side but scientists found that this permeability is due to some structural modification.
The endothelial cell that forms the lymphatic capillaries wall are not packed tightly and overlap each other very loosely which makes easy openings in the structure called mini valves.
When the pressure of fluid in interstitial space is high then the mini valves become open and allow the fluid to enter the lymphatic capillary. So mini valves are the unique structural modification that increases permeability in lymphatic capillaries.
Answer:Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water. In the melting process, the water molecules actually absorb energy.
Explanation:
The answer is d. Ingestion, digestion, absorption, elimination.
There are 4 phases of the digestive system function:
1. Ingestion - the process of the food entering the mouth.
2. Digestion - the process of breaking the food into small particles.
3. Absorption - the process of the absorbing small food particles into the blood from the intestines.
4. Elimination - is the process of removing the waste out of the body.
Global warming is heating up their environments and melting away their glacier habitat. If their home ever got completely rid of ice they'd die of a heat stroke.
