Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ
Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.

A patient has an inherited defect in the liver enzyme fructose 1,6-bisphosphatase and this results in an abnormally high levels
DedPeter [7]

If the live enzyme fructose 1,6- bisphosphatase defect is occured and this results in an abnormally high levels of lactate in the blood plasme this will result into the lactate will accumulate into the blood.

What is the work of fructose 1,6-biphosphatase enzyme?

In the liver, gluconeogenesis converts lactate to glucose. If FBPase-1 is defective, lactate cannot enter the gluconeogenic pathway in hepatocytes, building up in the blood.

A crucial enzyme in gluconeogenesis is fructose 1,6-bisphosphatase (FBPase). It is a possible target for drugs used to treat type II diabetes. Additionally, the protein is linked to a rare genetic metabolic disorder, and certain cancer cells lack the activity of the enzyme FBPase, which encourages glycolysis and aids in the Warburg effect.

WHICH!!!!! phenomena release CO2 into the atmosphere?
yulyashka [42]
A lot of carbon stored inside the Earth may soon re-enter the atmosphere, according to a new, global study on soil-based carbon. The massive release of carbon could be the equivalent of adding another fully industrialized country the size of the United States to the map over the coming decades.

Plants, animals, and microbes absorb much of the carbon dioxide released into the Earth's atmosphere by burning fossil fuels. As these plants and animals die, their carbon-based bodies become part of the soil, storing the equivalent of millions of tons of greenhouse gases in the dirt. As atmospheric carbon dioxide is a primary driver of climate change, some have pointed to this soil absorption as a helpful carbon sink, somewhat alleviating the human-caused warming of the planet. But as surface temperatures continue to rise, a lot of the carbon stored in the soil may be set to re-enter the atmosphere in a big way.
