SCIENCE TEST

• Amensalism is any relationship between an organism or a different species in which one organism is inhibited or destroyed while the other organisms remains unaffected
• Coevolution occurs when two or more interacting members of the community evolve in such a manner that they end up matching one another in terms of physical features
• Competition takes place when members of the same or different species attempt to use resources that are limited in supply and end up competing for these resources
• Intraspecific - same species
• interspecific - two different species
• Herbivory is the process whereby an animal eats a plant or a plant life organism such as a seaweed or phytoplankton
• Predation involves a violent encounter between a predator-prey, with former killing latter survive
• Scavenging is a relationship in which a living organism feeds on the remains or deed plants or animal
• Aristotle is considered the father of reasons and logic a Greek Scientist, teacher, and writer who lived from 384 to 332 BCE ( before common era ) is considerd one of the worlds greatest philosophersconsidered
• Mutualism is a relationship in which both species benefit from the relationship
• Parasitism A relationship in which one organism benefits and the other organism is harmed but not always killed
• Natural motion the motion of an object in response to a force applied to it.
• Violent motion is the motion caused by a force or result of push and pull
• Reference point is an object that stays in place and shows us that something is moving
• Distance is a numerical measurements of how far apart a objects or points are.
• Scalar quantities are quantities that just have magnitude but no direction
• Displacement is the shortest between the starting point and the final destination or final point
• Speed is the distance that can object travels per unit of time called rate of motion or speed
• Velocity is a vector quantity that indicates displacement, time and direction
• Instantaneous Velocity is the velocity of an object in motion at a specific point of time
• Classification of waves that moves through a material one place to another
• Nature of waves a wave is a disturbance that propagates through a medium
• Mechanical waves is a wave that is not capable of transmitting its energy through a vaccum
• Electromagnetic waves is a wave that does not require medium to transfer energy
• The amplitude of a wave is the distance from the top of the center line to the top of a crest or to the bottom of a trough.
• wavelength is the distance from any point on one wave to the same point of the next wave along
• Period is the time taken for the complete cycle of vibration to pass the given point
• Frequency is the number of wave that pass a point along a medium
• Velocity waves carry energy from one point to another without carrying the particles of their medium with them
• Sound is created when something vibrates and sends waves of energy into our ears
• Sound energy is produced by vibrating body
• Two types of sound is natural and man-made sounds
• Sound energy is produced when a force causes an object or substance to vibrate
• Solid have a compact particles, making them good transmitter of sound
• Gases have loose particles, making vibration travel through them more slowly
• reception of sound is one of your five senses. Its made possible by your ears
• The loudness of a sound depends on the sound's intensity of the energy use to produce vibrations in the sound's medium
• Pitch refers to the loudness or lowness of sound
• Quality the fullness and richness of sound and how pleasing it is to the ears measured the sound quality subjectively
• Pleasent sound is sound that will make you happy and comfortable
