Answer: Red blood cells placed in a solution with higher water concentration compared to their contents will gain water by osmosis that will then swell up and then burst.
Explanation:
Osmosis causes red blood cells to release water when they are exposed to sodium chloride solutions that are more concentrated than their internal environment (hypertonic solutions).
Hemolysis is the term for this process. In an attempt to balance the solute concentration, water is pulled out of the cells by the high concentration of sodium chloride outside the cells, creating an osmotic gradient. The result is that the cells shrink and may eventually rupture or burst. Lack of water reduces internal pressure and destabilizes cell membranes, causing red blood cells to burst.
This phenomenon underscores how important it is to maintain the correct balance of solute concentrations to protect the structural and functional integrity of red blood cells.

The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.
Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.
What are Skeletal muscles?Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.
Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement. While the spinal cord is associated with both movements directly or indirectly. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body.
Therefore, it is well described above.

Diffusion does not require any energy.
How does diffusion work?
A. Particles move from areas of higher concentration to
areas of lower concentration.
B. Molecules are moving AGAINST a concentration
gradient.
C. Heat is released making molecules move more quickly.
D. Cells only use energy to move substances across the
membrane.
A - Read below
Diffusion is simply particles spreading around. Think of it like spraying perfume in a room. Where the person sprayed the perfume would be a high concentration as there is a lot of that perfume there. However, on the other side of the room there would be little to no perfume. So the perfume spreads around until it is evenly distributed in the room.

The correct answer will be
1. Motor neuron
2. Spinal cord to muscle
In a Reflex arc, the Motor neuron carries the action potential from the Spinal cord to muscle.
The following are the components of a reflex arc:
A stimulus-detecting receptorA sensory neuron that will transmit the data to the spinal cord.A processing interneuron for the data (not present in all reflexes)A neuron that transmits signals to an effector organAn organ that carries out the reaction action.A brain circuit that manages a reflex is called a reflex arc. In vertebrates, the majority of sensory neurons synapse in the spinal cord rather than passing directly into the brain.
When Juan picks up a steel utensil the receptor detects the stimulus. A sensory neuron transmits the data to motor neuron which activates spinal cord which then signals the effector organ to carry out the reaction action i.e., Juan immediately drops the hot Utensil.
