Study Notes
Human Audio Perception
- The frequency range for audio perception in humans is typically between 20 Hz and 20,000 Hz (20 kHz).
Sound Waves
- Sound waves above 20 kHz are termed ultrasound.
- Sound waves below 20 Hz are known as infrasound.
Acoustics
- A scientist who works in the field of acoustics is known as an acoustician.
- Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound.
Sexual Reproduction
- The defining characteristic of sexual reproduction is the combination of genetic material from two parents to produce offspring with unique characteristics.
- Sexual reproduction does not occur in bacteria.
- A key difference between sexual reproduction in animals and plants is that animals typically have mobile gametes (sperm and egg cells), whereas plants have non-motile gametes.
- Gametes play a crucial role in sexual reproduction as they fuse to form a zygote, which develops into a new individual.
- The process in bacteria analogous to sexual reproduction is horizontal gene transfer.
