Explanation

• Transmission occurs when light passes through a substance without being absorbed, reflected, or refracted.
• The light wave maintains its intensity and direction as it travels through the substance, emerging unchanged on the other side.

Explanation

• Sound waves first enter the ear through the Ear Canal, also known as the external auditory meatus.
• From there, they travel to the eardrum, then to the cochlea, and finally to the auditory nerve.

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

• An element is a substance that consists of only one type of atom and cannot be further split up into simpler substances by chemical reactions.
• Examples: hydrogen (H), carbon (C), oxygen (O), and iron (Fe).

Explanation

• Limiting factors are the resources or conditions that restrict the growth, survival, or reproduction of organisms in an ecosystem.
• Examples: light, water, temperature, predation, and competition for resources.

Explanation

• Carbon Dioxide (CO2) is the gas used to produce energy in the form of glucose during photosynthesis.
• CO2 is the source of carbon atoms, which are used to synthesize glucose and other organic compounds during photosynthesis.

Explanation

• The olfactory bulb is the part of the brain that receives signals from odor receptors in the nose.
• It processing information about smells and odors.

Explanation

• The optic nerve is the nerve that carries visual information from the retina to the brain.
• Where it is interpreted and understood.
• It is responsible for transmitting electrical signals from the photoreceptors in the retina to the brain.
• It allowing us to see and interpret visual information.

Explanation

• The lens is responsible for refracting (bending) light to focus it onto the retina.
• It changes shape to adjust the focal length, allowing the eye to focus on objects at varying distances.
• This enables all light rays entering the eye to meet at a single point on the retina, creating a clear image.

Explanation

• Chromosomes are thread-like structures in the nucleus that carry genetic information in the form of DNA.
• They contain the instructions needed to build and maintain the cell, and control its functions.
