Asexual and Sexual Reproduction Quiz

Reproduction

• The biological process by which new individual organisms are produced from their parent or parents is called reproduction.
• Asexual reproduction involves an organism creating genetically similar or identical copies of itself.
• Asexual reproduction is not limited to single-celled organisms.
• The major puzzle for biologists related to sexual reproduction is why it is necessary for the survival of many species.
• Sexual reproduction typically requires the sexual interaction of two specialized reproductive cells called gametes.
• Sexual reproduction produces offspring with a unique combination of genetic characteristics from their parents.
• Bacteria reproduce by a process called binary fission.
• Starfish reproduce entirely by asexual means.
• The process by which a new organism is created from the genetic material of two organisms is called fertilization.
• Reproduction without seeds or spores is called vegetative propagation.
• In isogamous species, the gametes are similar in size and shape.
• Meiosis is the specialized type of cell division involved in sexual reproduction.
• Yeast can reproduce by budding.
• Parthenogenesis involves the development of an offspring from an unfertilized egg cell.

Sound Waves

• The frequency range for sound waves that elicit an auditory percept in humans is 20 Hz to 20,000 Hz.
• Sound waves with frequencies above 20,000 Hz are known as ultrasound and are not audible to humans.
• Sound waves with wavelengths of 17 meters to 1.7 centimeters in air at atmospheric pressure are called infrasound.
• The interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound is called acoustics.
• A scientist who works in the field of acoustics is called an acoustician.
• An audio engineer primarily focuses on the technical aspects of sound reproduction and recording.
• Sound is defined as a mechanical wave that propagates through a medium, producing vibrations that can be detected by the human ear.
• Sound can propagate through a medium due to the vibration of particles, creating a disturbance that travels through the medium.
• The vibration of an object creates vibrations in the surrounding medium, generating sound waves.
• The speed of sound within a medium is affected by its temperature, humidity, and pressure.
• The viscosity of the medium determines its resistance to the flow of particles.
• Wind can affect the speed of sound propagation by increasing or decreasing the speed of sound waves.
• During propagation of sound waves, particles of the medium oscillate back and forth, creating a series of compressions and rarefactions.
• The distance from a sound source affects changes in pressure, velocity, and displacement.
