Answer:
Because a drug acts on one type of receptor does not mean that it will act on another type.
Explanation:
As humans, we have receptors for two kinds of beta adrenergic compounds such as catecholamines. Cardiac muscle cells have beta 1 receptors that promote increased heart rate. Some drugs that slow heart rate are called beta blockers. Smooth muscle cells, however, have beta 2 receptors which mediate muscle relaxation. Blockers of these effects are sometimes used to treat asthma. The use of beta 2 antagonist drugs may be useful in asthma because a drug acts on one type of receptor does not mean that it will act on another type.

Natural resources can be classified into two main types:
1.Renewable resources
2.Non-renewable resources
Renewable resources are those which can be replenished and reused. These resources are abundantly present in the nature. Example wind, biomass. Non-renewable resources are those which cannot be replenished after single time use. Example fossil fuels, groundwater, natural gases, forests. These resources needs to be conserved and their use should be judicious. Government should participate to prevent excess and destructive use of natural resources. Such as it should prevent deforestation. Many buisnesses requires the use of fossil fuels and natural gases which should be limited as these resources takes several years to be produced under the heap of earth. Citizens should prevent the use of groundwater in excess as this is the water reservoir which takes many years to be filled by natural means such as rain, agricultural irrigation, river and lakes.
