These experiments demonstrate the principle of osmosis by showing how water molecules move across a selectively permeable membrane in response to differences in solute concentration on either side of the membrane.

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration).  In the experiments we performed, we used a selectively permeable membrane in the form of a potato slice. We placed the potato slice in different solutions of varying concentrations of salt or sugar.  In the first experiment, we placed the potato slice in distilled water. Since the concentration of solutes in the potato is higher than the concentration of solutes in the water, water molecules move from an area of high concentration (water) to an area of low concentration (potato), resulting in the potato slice absorbing water and swelling in size. This is an example of osmosis in action.
In the second experiment, we placed the potato slice in a solution of saltwater. Since the concentration of solutes in the saltwater is higher than the concentration of solutes in the potato, water molecules move from an area of high concentration (potato) to an area of low concentration (saltwater), resulting in the potato slice losing water and shrinking in size. This is another example of osmosis in action, but in the opposite direction.
Overall, these experiments demonstrate the principle of osmosis by showing how water molecules move across a selectively permeable membrane in response to differences in solute concentration on either side of the membrane.

The extracellular matrix cells connect  through Integrins. Integrins are a family of transmembrane proteins that act as receptors on the surface of cells. So, the correct answer is option C.

They interact with other cell-surface proteins and the extracellular matrix (ECM) to build a vast network of protein complexes that allow the cell to communicate with its surroundings.

Integrins play a significant role in cell adhesion, migration, signalling, and development and mediate a variety of cell-matrix and cell-cell interactions.  Two alpha and two beta subunits that are joined by disulfide bonds make up integrin proteins.

The intracellular domain binds to actin and other cytoskeleton-related proteins, whereas the extracellular domain interacts to proteins in the ECM.

The cell can perceive and respond to messages from its environment thanks to this binding, which also enables it to attach to other cells and its environment.

Answer:

Agonist muscles.

Explanation:

Agonist muscles act as prime movers as they are most responsible for a particular movement in the human body.

The ciliary muscle of the eye is solely innervated by the parasympathetic division.

The ciliary muscle is a smooth muscle located in the eye that controls the shape of the lens, allowing the eye to focus on near or far objects. The ciliary muscle is innervated solely by the parasympathetic division of the autonomic nervous system. When the parasympathetic nervous system is activated, the ciliary muscle contracts, causing the lens to thicken and focus on nearby objects, a process called accommodation. When the parasympathetic nervous system is inhibited, the ciliary muscle relaxes, allowing the lens to flatten and focus on distant objects.

On the other hand, the arrector pili muscle of the hair follicle (A), sweat glands (C), and adipose tissue (D) are not innervated solely by the parasympathetic division of the autonomic nervous system. These structures receive innervation from both the sympathetic and parasympathetic divisions or may not be innervated by the autonomic nervous system at all. For example, the arrector pili muscle is innervated by both sympathetic and parasympathetic nerves, while sweat glands and adipose tissue are not innervated by the autonomic nervous system.
