What is the relationship between matter and energy in an ecosystem.
Answer:
As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created. So, during all ecosystem processes, energy and matter are conserved
Explanation:
Prothrombin is a plasma protein that is involved in the clotting process of blood. Its normal concentration in plasma is 30mg/200ml. What percent of the plasma is prothrombin?.
Given what we know, we can confirm that Prothrombin circulates through the blood at a percentage of about 15%.
How do we reach this percentage value?In order to reach this value, analysis of blood samples have shown the exact amounts that circulate per every set amount of blood, we can then divide these values in order to get a decimal value for the percentage, which after converting leads us to the answer of about 15%.
Therefore, we can confirm that Prothrombin circulates through the blood at a percentage of about 15%.
