Answer:

Concentration is the ratio of solute in a solution to either solvent or total solution.

Explanation:

Concentration basically means how much of something is in a given area. A gas, for example, can be highly concentrated in a given area, but a liquid cannot be concentrated and always takes up the same amount of space.

Answer:

Cycling, also called bicycling or biking, is the use of bicycles for transport, recreation, exercise or sport.[1] People engaged in cycling are referred to as "cyclists",[2] "bicyclists",[3] or "bikers".[4] Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent and similar human-powered vehicles (HPVs).

Cyclists in the 2009 Tro-Bro Léon race.

Police cyclists in London.

A woman cycling in Sri Lanka.

A bike lane in Amsterdam. Bike lanes are dedicated for cyclists and provide shelter from vehicle traffic.

Bicycles were introduced in the 19th century and now number approximately one billion worldwide.[5] They are the principal means of transportation in many parts of the world.

Cycling is widely regarded as an effective and efficient mode of transportation[6][7] optimal for short to moderate distances.

Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a reduced consumption of fossil fuels, less air or noise pollution, reduced greenhouse gas emissions,[8] and greatly reduced traffic congestion.[9] These have a lower financial cost for users as well as for society at large (negligible damage to roads, less road area required). By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve.[10]

In addition, cycling provides a variety of health benefits. The World Health Organization (WHO) states that cycling can reduce the risk of cancers, heart disease, and diabetes that are prevalent in sedentary lifestyles.[11][12] Cycling on stationary bikes have also been used as part of rehabilitation for lower limb injuries, particularly after hip surgery.[13] Individuals who cycle regularly have also reported mental health improvements, including less perceived stress and better vitality.[14]

Among the disadvantages of cycling are the requirement of bicycles (excepting tricycles or quadricycles) to be balanced by the rider in order to remain upright, the reduced protection in crashes in comparison to motor vehicles,[15] often longer travel time (except in densely populated areas), vulnerability to weather conditions, difficulty in transporting passengers, and the fact that a basic level of fitness is required for cycling moderate to long distances.
