If a juice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average and any overfilling or underfilling results in the shutdown and readjustment of the machine, in order determine whether or not the machine is properly adjusted, the correct set of hypotheses is H0: µ=12 and Ha: µ≠12. (Option C).
In scientific context, a hypothesis or hypotheses refers is a testable statement defining the relationship between variables or a proposed justification for an observed phenomenon. In this case, since the drink filling machine that is perfectly adjusted fills 12 ounces of drink on an average, after readjustment to determine if the machine is properly adjusted, the hypotheses that must be test that if the average of filling is equal to 12 ounces or not.
Note: The question is incomplete as options are missing. The options are a) H0: µ < 12 and Ha: µ≥12, b) H0: µ≤12 and Ha: µ>12, c) H0: µ=12 and Ha: µ≠12, d) H0: µ≠12 and Ha: µ =12.

Answer: tight junction; desmosomes
Explanation: Tight junctions are connected areas of the plasma. They form a water tight seal and acts as barrier against the movement of water, solute and prevents passage of materials between the cells or epithelial layers.
Desmosomes forms a strong connection that joins intermediate filament of adjacent cells, they can be viewed as rivets through the plasma membranes of adjacent cells.
