### transport:

Active transport
* allows cells to transport materials against a concentration gradient.
* appears to be limited to drugs structurally similar to endogenous substances.
* can move substances against a concentration gradient
  - only occur at intact, closed membranes
* consumes metabolic energy to move solutes against their concentration gradients.
* involves mineral-specific membrane transport proteins
  - movement of substances against a chemical gradient
  - using energy to move substances against a diffusion gradient
* is another form of diffusion
  - especially important in maintaining proper ion concentrations inside cells
  - important part of homeostasis as well as many important metabolic processes
  - required to remove sodium from the cerebrospinal fluid
  - slowed, decreasing the absorption of nutrients such as sugar, calcium, and iron
  - used to adjust concentrations of various salts
  - vital to all organisms
  - yet another form of diffusion
* require energy to function properly.
* requires a carrier molecule and a form of energy
  - the use of energy
* uses cellular energy to move substances across a cell membrane
  - energy to move materials through a membrane

Bulk transport
* allows for nutrients to be transported over greater distances
  - rapid communication between different parts of the body
  - waste products to be removed more efficiently
* is responsible for the movement of nutrients and hormones in both animals and plants.

### transport:

Bus
* Some busses allow bicycles to be attched to the front.
* are a reliable means of transport.
* are a very common form of local transportation
  - popular form of transportation in Mexico
* are an important component of a sustainable transportation system
  - part of a community's transportation system
  - big, heavy vehicles and cause a vibration and shaking of residences
  - five times as fuel efficient as cars
  - simply the paths, or wires, that connect one component to the other
  - slower than automobiles since they are stuck in traffic
* are the main form of inter-city transportation
  - mainstay of public transportation in Albania
* are the most common public transport
  - transport of the masses
  - important form of public transportation in Taipei
  - popular method of transport for both urban and inter-city travel
  - streetcars of today
* carry teams
  - wrestle teams
* cause extreme air pollution and give off a lot of carbon dioxide.
* es are efficient at moving people over distances of less than a mile or two
  - just bundles of wires for carrying related electrical signals
* have mass
  - numbers and symbols to identify what part of the city they cover
  - routes
* help reduce dependency on auto use, the main contributor to air pollution and global warming.
* includes sections.
* is public transport
+ Bromsgrove, Transport: Towns in Worcestershire
  * There is also a bus station in the town centre. Buses travel from the bus station to many places in Worcestershire and the West Midlands.
+ Everland, Attractions: Theme parks :: South Korea :: Tourism
  * Bus ride through the zoo where various animals wandering around freely. In the caged bus, the visitors will see the roaming lions, tigers, bears, and sometimes some animals come up to the bus to catch the feed thrown by the driver.
+ Public transport, Types of public transport
  * The main types of public transport are buses, trolleybuses, trams and trains. Trams were first used in the late 1860s and used to be pulled by horses. Now trams are electric and run on a line of cable. Buses drive on the road, like cars do. Trolleybuses are like buses, but they use electricity from two wires above the road. Trains run on a track and are very fast. Many places use trams and trains as a form of public transport.

### transport | bus:

Minibus
* are also common in bigger cities
* have forward facing seats with seat or lap belts.
