(20 points) [URGENT] give a hypothesis on how the mass of potato chips is expected to change in each solution
lbvjy [14]

I predict that the potato  in the lowest sugar solution

(water) will gain the most mass through osmosis, whereas the 80% sugar

concentration will lose the most mass through osmosis. I predict this

because I think that the potato chips will try to gain and lose water

between the two sides of its cell wall in order to reach an

equilibrium between them because the 80% sugar solution has a high

amount of sugar molecules, which can not diffuse through the membrane,

I think that the potato will lose water in order to make the solution

on the outside of its membrane equal to the water concentration on the

inside thus losing mass. I also predict that the other

concentrations (60%, 40%, and 20%) will lose mass, but in lower

numbers compared to the 80% sugar solution (the lower the

concentration, the higher the mass). However, since the distilled

water carries no sugar molecules, I think that the potato chip will

gain water to create a balance between the two sides of the cell wall,

making it gain mass.

In an electromyography (EMG) read out, all motor units can look slightly different because:_____.
lesya [120]

Answer:

a. every muscle has a varying number of motor units so they can generate different frequencies.

e. each motor unit can innervate a different number of muscle fibers.

Explanation:

Electromyography (EMG) is a diagnostic procedure used to measure the response of muscles and nerves to electrical activity. A motor unit is composed of one motor neuron and muscle fibers it innervates. The number of muscle fibers in each motor unit can vary among different muscles and even among motor units within the same muscle. Each motor unit is known to innervate a variable number of muscle fibers, but each single muscle fiber is innervated by only one motor.
