Answer:
Because proteins and lipid tails are free to move and are not bonded by strong interactions with each other.
Explanation:
The plasma membranes have two layers of phospholipids in which proteins are present. The hydrophobic fatty acid tails of phospholipid layers make the inner core of the membranes. However, the tails are not bonded to each other and make a fluid-like base in which proteins are present. Also, the membrane proteins are not bonded to the phospholipids and are free to change their position within the phospholipid leaflets. This is why the model is described as a fluid mosaic model.

Answer:
Echinoderms use its tube feet for "<u>movement, respiration and taking food".</u>
Explanation:
Tube Feet are tiny tube like projections on oral side of echinoderms. They use it for movement, food and respiration. Echinoderms also use them to stick the ocean floor and move at a leisurely pace.
Decomposition is the process that plays an important role in cycles of carbon and nitrogen
