Q:

What role does photosynthesis play in the carbon cycle?

Answer

In the process of photosynthesis, plants need the sun's energy, water to make food for themselves in the form of ATP ( adenosine triphosphate ) , which is packages of energy.


Carbon :


coming into the plants ( or algae ) along with water make those ATP into a bigger molecule, which is know as glucose.


Formula: 6 CO2 + 6 H2O + Suns Energy -> glucose + oxygen


Photosynthesis has an affect on the carbon cycle because it reduces the amount of CO2 in the air and redirects it into sugars which feeds animals as well as humans.

Q:

In economics, if a good is inelastic,

A) its supply or demand is not sensitive to price changes. B) consumers have lost an interest in purchasing it.
C) producers have lost an interest in manufacturing it. D) its supply or demand is too sensitive to price changes.
 
Answer & Explanation Answer: A) its supply or demand is not sensitive to price changes.

Explanation:

If the percent change in quantity demanded is less than the percent change in price, economists label the demand for the good as inelastic.

A good that is inelastic does not have very stretchy demand. In economic terms, the quantity demanded does not change a lot when the price changes.

 

So, if the price of a good increases by 10 percent and the quantity demanded decreases by only 5 percent or less than 10, that good is said to have inelastic demand.

 

Hence, in this case, consumers are not considered very sensitive, or responsive, to a change in the price of that good.
