They all have a rocky surface
Answer:
<u>c. Sucrose and glucose</u>
Explanation:
The paramecium is a large, single-celled microbes, surrounded by a plasma membrane. Simple diffusion occurs in cells across plasma membranes, as a form of passive transport. In diffusion, solutes move from regions of high concentration to regions of low concentration across the plasma membrane.
Here, the internal environment has higher concentrations of sucrose and glucose, but lower concentrations of fructose, thus the solutes will move along their concentration gradient, to where the concentrations are lower. In order for the fructose molecules to move out of the cell, the molecules have to move against their concentration gradient - a process requiring energy known as active transport.

Answer:
isometric contraction
Explanation:
An isometric contraction occurs as the muscle produces tension without changing the angle of a skeletal joint. Isometric contractions involve sarcomere shortening and increasing muscle tension, but do not move a load, as the force produced cannot overcome the resistance provided by the load.
