This
is a specific response because in order to fight antigens, white blood cells,
the most important cells of the immune system, must produce large, Y-shaped
proteins known as antibodies to fight these invaders. This is a type of
specific defense (as I have identified antibodies as specific defenses is the
chart above).

Answer:
The water potentials (Ψ) of the cell and its surroundings are the same.
Explanation:
When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.
When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.
The optimum temperature of salivary amylase ranges from 32°C to 37°C.<span>This applies to the human body since salivary amylase is suitable to function within these temperatures. After </span>37°C<span>, the graph then steeply declines as a result of loss of activity. At 50°C and 70°C, salivary amylase is denatured.</span>
