Explanation

Kinetic energy is the energy of motion, and any object that is moving has kinetic energy.

• A moving car (energy from motion)
• A moving runner (energy from motion)
• A moving bicycle (energy from motion)

Explanation

Potential energy is the stored form of energy in an object, which can be released when the object is moved, stretched, or compressed.

Examples:

• Gravitational potential energy (e.g., a ball at the top of a hill)
• Elastic potential energy (e.g., a stretched rubber band)
• Electrical potential energy (e.g., a charged battery)

Explanation

• Dentist mirrors are typically concave mirrors.

• Rear-view mirrors
• Blind Corner mirrors 
• Security mirrors

Explanation

• Respiration requires two main materials: Glucose (C6H12O6) and Oxygen (O2).
• Glucose is the energy source that is broken down to produce energy.
• While Oxygen is necessary for the process of cellular respiration to occur.

Explanation

• The pupil is the small, circular opening in the center of the iris that appears as a black dot.
• It is the entrance point for light to enter the eye.
• It is responsible for controlling the amount of light that enters the eye by changing its size.

Explanation

• A group of similar cells that perform a specific function combine to form tissue.
• Tissues then combine to form organs.
• Organs work together to form systems.

Explanation

Potential energy is stored energy due to an object's position or state.

Examples:

• A stretching spring (elastic potential energy)
• A stone lying at a height (gravitational potential energy)
• A book placed on a table (gravitational potential energy)
• A pressed spring (elastic potential energy)

Explanation

• A parasite is an organism that feeds and lives in or on part of another organism (host), often causing harm to the host.
• In this case, the mosquito is feeding on the human's blood, making it a parasite.

Explanation

Explanation

• Unicellular organisms, like Amoeba and Paramecium, are composed of only one cell.
• Plants (fern and coconut) and animals (hydra and eagle) are composed of many cells, making them multicellular organisms.
