Answer;
-Pellicle
Explanation;
-Protist cells may contain a single nucleus or many nuclei; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.
-On a paramecium's exterior is found the pellicle. The pellicle is stiff to maintain the paramecium's shape and provide stability but it is also flexible to allow movement. It also acts as an attachment site for external organelles such as cilia.
The best explanation for the greater rate of transport for solute A than for solute B at higher solute concentrations is that there are more frequent collisions of molecules of A than that of B.
<h3>How does concentration affect transport of molecules</h3>
- Concentration is the amount of solute dissolved in a given volume of solution.
Given two solutions A and B of different concentrations, The solution of higher concentration will have a higher amount of dissolved solutes.
Given A has a higher concentration, the solutes will collide with themselves much more than in B.
Hence, the molecules of A will tend to move faster than that of B.
Therefore, the best explanation for the greater rate of transport for solute A than for solute B at higher solute concentrations is that there are more frequent collisions of molecules of A than that of B.
