Answer: This is the definition and example of Osmosis.

Explanation: Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a region of high concentration of solvent to a less concentration of solvent, thus making the concentrations on each side of the membrane equal.

The cell membrane is also a selectively permeable membrane which allows only certain substances to pass through it. Mostly molecules move from a side where their concentration is high to a side where their concentration is less to make the concentration equal on both sides.

How does the human brain store and retrieve memories?

krek1111 [17]

Answer: After consolidation, long-term memories are stored throughout the brain as groups of neurons that are primed to fire together in the same pattern that created the original experience, and each component of a memory is stored in the brain area that initiated it (e.g. groups of neurons in the visual cortex store a sight, neurons in the amygdala store the associated emotion, etc).

Smooth muscle can be found in the walls of hollow organs and passageways, they can contract and they have fibers of actin and myosin tuning though it arranged in an staircase form.

In the images I added you can see how smooth muscle looks when observed in a microscope, wider in the middle and elongated at the ends, and the staircase arrangement.
