A layer of smooth cartilage at their ends, which cushions the bones and prevents them from rubbing directly against one another. The whole joint is also enclosed in a synovial capsule, which is full of synovial fluid. The synovial fluid acts like the oil in an engine, lubricating the joint and preventing the cartilage from becoming worn down.
Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.
<u>EXPLANATION: </u>
- Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body.
- But the polysaccharide like cellulose cannot be absorbed by our body.
- Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity.
- Also, molecules of each micro-fibril are so tightly packed structure and prevent the penetration of enzymes.
- Thus, cellulose degradation requires a complex enzyme and cellulose.
Primary succession occurs when a natural disaster like an EQ, volcanic eruption, or flood, occurs to an area where there is no plant or animal life. The first organisms to appear are lichens, which over a long period of tome, will begin to form soil.
Answer and Explanation:
Both clouds and fog are closely related to precipitation.
This can be explained first by the formation of clouds and fog, which begin when the air contains water vapor. This <u>water vapor is produced when there is an accumulation of moisture in the enviroment which leads to the formation of clouds. A similar process occurs with the formation of fog, which comes from saturation, that occurs after the evaporation and condensation processes that take place after precipitation (water cycle). </u>
Moreover, some types of clouds (cumulonimbus) are associated with precipitation as they could be accompanied by climatic phenomenon such as rain and snow.
