Answer:
tachyphylaxis
Explanation:
Addictive or tolerance - unofficial name.
 This is accompanied by the addiction of the body to the medicine. The receptors memorize the chemical substances of the drug and when they are reintroduced, they do not react to it. In this case, the medicine is rapidly eliminated from the body as drug is not digested

Because the sun provides not only provides for living things, it provides for some indirectly because the sun is everywhere. That being said, a good example would be the grass.

Answer:(B) decrease protein production
Explanation: nitrogen gas in the atmosphere is the source of nitrogen which is useful to plants.
In the nitrogen cycle, nitrogen gas is converted to it's compounds and then back to it's gas form.
The nitrogenous cycle involves fixation, mineralization, nitrification and denitrification .
In the first three states, nitrogen undergoes changes into a state where it can be absorbed by plants.
In denitrification,nitrates (useful form of nitrogen) are converted into gaseous nitrogen.organisms involved in this process are called denitrifying bacteria eg Pseudomonads sp.
Nitrogen is an important element.
It is useful for the production of protein, DNA, RNA and chlorophyll.
When it is deficient in the soil,it affects the synthesis of proteins and yellowing of leaves due to decrease in chlorophyll
 
        
                    
             
        
        
        
- speed up chemical reactions in the body / hormones
- transport materials across the body
- regulate body tissues and organs
Ex: insulin
Ex: hemoglobin in the blood transport oxygen around the body..yea XD
