### pesticide:

Traditional pesticide
* Most traditional pesticides are dangerous for kids and pets, and often harmful to the environment.
* are harmful to the environment and to peoples health.
* have limited use because of their toxicity and ecological damage.

### phantom idea:

Institutional racism
* is addressed, particularly as it pertains to racial profiling
  - racism without a perpetrator
  - the subordination of any one cultural community relative to another
* phantom idea.
* runs across every border, as well as differences in religion.

Phase
* Most phases have distinct physical properties
  - mechanical properties
* Most phases undergo binary fission
  - sequential fission
* Some phases dissolve in liquids
  - have conductivity
* Some phases have low conductivity
  - thermal conductivity
* Some phases occur in larval life
* affect growth.
* are a way to group behaviors and relate variant objects with the same identity
  - appearances
  - different from states of matter
  - part of cycles
  - physically separate regions of homogeneous chemistry
  - points
  - time periods
* begin with development.
* consist of development
  - follow steps
* depend on availability
  - conditions
  - economic conditions
  - growth conditions
* follow events.
* have advantage
  - functions
* include effort
  - excitement
* influence behavior.
* involve gather requirements
  - key steps
  - production
  - water
* limit extent.
* occur during periods.
* occur in environments
  - natural environments
* persist for time.
* refer to the different shapes the moon appears from the earth.
* refers to the instantaneous relationship between voltage and current
  - relative point in the on-off duty cycle
* require participation.
* shift keying' way of transmitting information
  - the phase of the sine wave is changed
* take places.
+ Phase-shift keying: Radio
  * Phase shift keying' is a way of transmitting information. This is done by modulating the phase of a carrier wave. In many cases, this allows to better use the bandwidth available.

### phase space:

Dynamical system
* Some dynamical systems are well represented as collections of partial differential equations.
* are chaotic, unpredictable
  - pervasive in the modelling of naturally occurring phenomena
  - systems whose state changes over time as in the case of erosion and growth
* branch of mathematics which studies processes which change.
* is phase space
* occur in every branch of science.

Color phase
* Some color phases have but two small black spots at the tip of the wing covers.
* differ according to age.
* do occur with red fox, even in the same litters.

Different phase
* are a normal part of life.
+ Liquid crystal: Physics
  * Liquid crystals' are special substances that are usually liquid, but that show certain properties of a solid crystal. There are many different types of liquid crystal phases. Different phases are different because their optical properties are different. Using a microscope and a polarized light source, different liquid crystal phases will have different textures. This is also shown in the image.

Gibbous phase
* are phases between quarter and full phases.
* is formed directly after the full moon.

Lag phase
* Most lag phases depend on growth conditions.
* depend on conditions

Stationary phase
* Dying and dividing organisms are at an equilibrium.
* results from a situation in which growth rate and death rate are equal.

Phenolic compound
* Most phenolic compounds belong to the flavonoids.
* contain a six-membered aromatic ring with at least one OH group.
* have a range of uses, including as an input to composite wood products.
* secreted by the roots, e.g. luteolin, serve as signals.
* share the same fundamental structural unit, phenol, shown above.
