Answer:Water level will rise in compartment A.

Explanation: Osmosis is the movement of water molecules from an area of higher water concentration to an area of lower water concentration through a semi permeable membrane. Compartment B has higher water concentration than compartment A because compartment B has 10% salt concentration which is lower than 30% salt concentration in compartment A. Therefore, water molecules will move from compartment B to compartment A thereby causing a rise in the water level in compartment A.

<h2>Cannon -Bard theory</h2>

Explanation:

  • Alone in the woods, Pedro hears a noise. He thinks he sees a bear coming toward him. His heart starts pounding and then, a moment later, he realizes how frightened he is. This sequence of events is BEST explained by the <u>Cannon-Bard t</u>heory of emotion.

According to Cannon-Bard theory, all the emotional expressions occur due to the stimulation of hypothalamic structures present in brain. This theory also states that feeling and physiological effects of an emotional stimuli occurs simultaneously.

Here, James thinks that a bear is coming, this is a stimulus. His heart starts pounding that is the physiological effect of the stimulus and the next moment he feels frightened which is a feeling.

So we conclude that in this case, the physiological effect and feeling of emotion occurred simultaneously. So these sequence of events is best explained  by Cannon-Bard's theory.
