- a form of reproduction in which new individuals are formed without the involvement of gametes
- calorie
- unit of energy; the amount of heat needed to raise on gram of water on degree Celsius at standard atmospheric pressure
- dependent variable
- factor being measured or observed in an experiment
- acceleration
- rate of change in velocity, usually expressed in meters per second; involves an increase in speed and/or change in direction

- an ecological community, together with its environment, functioning as a unit
- biotic
- factors in an environment relating to, caused by, or produced by living organisms
- efficiency
- the relative effectiveness of a system or device determined by comparing input and output

- outermost layer of Earth covering the mantle
- dominance
- tendency of certain(dominant) alleles to mask the expression of their corresponding (recessive)alleles
- conduction
- the transmission of heat through through a medium and without the motion of the medium
- conservation of energy
- a fundamental principle stating energy cannot be created nor destroyed but only changed from one form to another
- deposition
- the process by which sediment is carried by forces and left in a certain area
- gene
- a specific part of a chromosome or sequence of DNA that determines a particular feature or characteristic in an organism
- convection
- heat transfer in gas or liquid by the circulation of currents from one region to another
- amplitude
- in any periodic function(e.g. a wave) the maximum absolute variation of the function
- allele
- any of two or more alternate forms of a gene that an organism may have for a particular trait
- erosion
- a combination of natural processes in which materials from Earth's surface are loosened, dissolved, or worn away and transported from one place to another
