Study Notes
Human Hearing
- The cochlea is the primary structure responsible for hearing in humans.
- It converts sound waves into neural signals, which are sent to the brain for interpretation.
Skin Function
- The primary function of the skin is to act as a barrier, protecting internal organs from environmental hazards.
- It regulates temperature and water loss while also providing sensory information through receptors.
Lifeless Classification
- In biology, non-living entities such as minerals, water, and gases are classified as lifeless.
- These do not exhibit characteristics of life, such as growth, reproduction, or metabolism.
Eye Functionality
- The lens is the part of the eye responsible for focusing light onto the retina.
- It adjusts its shape to help in precise aiming of light rays for clearer vision.
Dead Organisms
- Dead organisms lack biological functions such as respiration, growth, and reproduction.
- They do not respond to external stimuli and can undergo decomposition processes.
