Photosynthesis releases oxygen (O₂).

Pepsin breaks down proteins into smaller peptides.

Formula: $V = IR$

Law of Inertia: A body remains at rest or in uniform motion unless acted upon by an external force.

Concave lenses are used to correct myopia because they diverge light rays before reaching the eye.

The First Law of Thermodynamics states that energy can neither be created nor destroyed, only transformed.

Ohm’s law states that V = IR, where V is voltage, I is current, and R is resistance.

Sound requires a medium (solid, liquid, or gas) to travel, so it cannot travel through a vacuum.
