eased by an average of 8% in the past decade. Scientist 1 concluded that the increase was a result of the increasing population of the city. Scientist 2 concluded that the increase was a result of an active volcano several miles from the city. Which scientist's conclusion is valid?

Answer:

Scientist 1

Explanation:

<em>The conclusion of scientists 1 is valid.</em>

Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>

Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.

<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>

Which statements accurately describe how fructose metabolism in the liver differs from glucose metabolism?
tiny-mole [99]

The fructose 1-phosphate pathway can deplete intracellular phosphate/ ATP.

Explanation:

Fructose 1-phosphate is a derivative of fructose. For understanding in better way fructose metabolism has three enzymes. Fructose- bisphosphate aldolase B, fructokinase and Adenosine triphosphate. These all are present in liver and kidney of human as well rat. In liver rapidly fructose is change to fructose 1 through fructokinase.

Where do light-independent reactions occur?
murzikaleks [220]
The light-independent reactions occur in the storm of the chloroplast<span>. The light- independent reactions are "independent" from light so they can happen else where. The light-dependent reactions happen in the thylakoid membrane of the chloroplast where the light is absorbed, and the reactions depend on the light.</span>
