Buffer
* Most buffers are weak acids or weak bases that combine reversibly with hydrogen ions.
* allow mixing of pesticides of different acidity or alkalinity.
* also help prevent shoreline erosion and provide shade, food, and shelter for wildlife
  - provide fish and wildlife habitats and preserve the ecosystem of the waterways
  - trap snow and reduce blowing soil in areas with strong winds
* are a special case of the common ion effect
  - compounds
  - devices
  - memory devices
  - mixtures of weak acids or bases and their salts
  - part of cars
  - particularly effective in removing nitrates from the soil water
  - power tools
  - resources
  - simply areas where the natural vegetation is encouraged to grow
  - social exchanges that cushion or mitigate the negative effects of life stresses
  - storage areas within programs, and are frequently used to store program inputs
* can also reduce the amounts of phosphorous and sediments that enter watercourses.
* cause acidic solutions to become alkaline, and alkaline solutions to become acidic.
* decrease breakdown of pesticides in alkaline water.
* help to maintain intake as well as fat test, especially in low fiber diets.
* neutralize both acids and alkalies and generate less heat.
* prevent changes in pH byabsorbing or releasing hydrogen ions
  - the pH of a solution from changing when an acid or base is added
* remove a significant amount of nitrate and store it in plant material.
* resist a change in the pH of a solution when small amounts of acid or base are added.
* serve as temporary storage areas in circuits.
* stabilize pH of a solution by taking up excess hydrogen or hydroxide ions.

### buffer:

Chemical buffer
* bind protons.
* release protons.

Conservation buffer
* are a proven method for enhancing water quality.
* can help protect wildlife habitat in a development.

Riparian buffer
* are crucial to the protection and enhancement of the water resources of New York
  - important to the health of a stream
  - trees, shrubs, or grass next to streams
* contain trees and shrubs.
* have a tremendous influence on water quality
  - substantial, or little, effect on water-body condition

### build:

Body type
* Most body types can drink water immediately before and after a meal without any problems.
* Some body types gain weight easily and are also more susceptible to cellulite.
* are often consistent from lifetime to lifetime, though the size of the body can vary
  - physique
* becomes a focus of attention in adolescence.
* is often similar among mothers or sisters.

Building insulating material
* An insulating material building material
* Insulating material appears in magenta.
* Insulating materials are building materials
  - protective covering
  - skin irritants
  - have a high level of resistance to conduct heat
* Most insulating materials have dielectric strengths greater than air's.

Building material
* All building materials are mixtures of a number of chemical compounds identified as molecules.
* Many building materials are soil based
  - suitable nutrient sources for fungal growth
  - provide suitable nutrients that encourage mold to grow
* Most building materials are dimensionally unstable
  - tolerant of a certain amount of moisture
  - shield electric fields to some extent
* Some building materials have a high fire resistance rating and can slow down the flames
  - release toxic chemicals into the air
* are also important in considering aesthetics, thermal properties, and economics
  - artifacts
* can also release toxic chemicals to the indoor environment.
* is an artifact
  - any material which is used for construction purposes
