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.
Answer:
new technological advances
Explanation:
The carrying capacity indicates the maximum population of a particular species that a given area of habitat can support over a given period without destroying or depleting the resource base.
Carrying capacity can be affected by factors such as technological advances, trade and use of fossil fuels for energy . Changes in technology modify the carrying capacity of a population. An example is the use of irrigation and fertilisation in agriculture or shortening rotations between crops, which increases the number of people who can be fed from the resources of a given population due to increased yield.
-3x + 3(2x - 6) = 6
-3x +6x - 18 = 6
3x - 18 = 6
3x = 6 + 18
3x = 24
x = 8

Answer:
The major form of fat stored by the body. A triglyceride consists of three molecules of fatty acid combined with a molecule of the alcohol glycerol. Triglycerides serve as the backbone of many types of lipids (fats). Triglycerides come from the food we eat as well as from being produced by the body.
