The most likely unit for measuring the size of a typical mature yeast cell is micrometer. Micrometer (μm) or micron is unit of length which is 10⁶ times smaller than meter. Yeast cells are very small, usually yeast cells are 3-4 μm, but some species can reach size of 40 <span>μm.</span>
2 in the first and remaining 4 in the (outer) shell

Explanation:
The correct answer is muscularis externa.
The muscularis externa refers to a section of muscle in various organs in the vertebrate body, adjacent to the submucosa. It is accountable for the gut movement known as peristalsis.
In comparison to the majority of the remainder of the digestive tract, the muscularis externa of the upper section of the esophagus comprises of striated muscle. It is accountable for peristaltic movement and segmental contractions in the GI tract.
These muscles make the movement of food and churn in combination with the digestive enzymes down the GI tract. The muscularis externa comprises of a longitudinal outer muscular layer and an inner circular layer.
Answer:
There is a certain water potential maintained in the body of the paramecium, which can change in response to changes in its environment. When the water solute level is increased all the way up, the water potential in the surrounding is a lot lower than the water potential inside the paramecium. Due to this steep water potential gradient, water will leave the paramecium's cell into the surrounding via osmosis. Water being transported out of the paramecium will cause it to dehydrate and die.
In the opposite case where the solute level is lowered all the way down, no water will enter the paramecium cell because its water potential is lower than the surroundings. The difference in water potentials is so great that the water entering the paramecium's cell will cause to burst and die.
Note: remember that diffusion and osmosis takes place down the concentration gradient. The concentration of one environment is determined in reference to another.
Hope that answers the question, have a great day!
