12 is the total number of NADH FADH2 molecules that will be produced.
In each citric acid cycle, one molecule of FADH2 is formed during the conversion of succinic acid to fumaric.
The CAC is called a cycle because the starting molecule, oxaloacetate is regenerated at the end of the cycle.
It is also known as Krebs cycle. This is actually a part of a huge process called cellular respiration. The citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules.
NADH:- It is an energy shuttle that delivers high energy electrons to the electron transport chain where they eventually get to power the production of 2 to 3 ATP molecules.
FADH:- This is another energy shuttle that carries high energy electrons to the electron transport chain, where they will ultimately drive production of 1 to 2 ATP molecules.

Answer:
Option B, 2 percent
Explanation:
Complete question is
In a community, autotrophs generate 1,000 calories per hour of GPP and 500 calories per hour of NPP. Primary consumers convert 10 calories per hour into their own biomass. What is the ecological efficiency in the link between autotrophs and primary consumers in this community?
1 percent
2 percent
20 percent
10 percent
Solution
Given
Autotrophs generating calories per hour of GPP 
Autotrophs generating calories per hour of NPP 
The rate at which the primary consumers convert calories per hour into biomass is equal to 
calories per hour
The ecological efficiency is equal to" the rate of calorie conversion to biomass" divided by the net produced calories multiplied by 
Rearranging the above relation in a mathematical equation, we get -
Hence, option B is correct
Answer:
Because of using fossil fuels nowadays it is used to air pollute the earth causing global warming.
Explanation:
The difference between the speed of 100m race and 5000m race is larger because the difference between speed is more.
Explanation:
In the question given above we can see that in the first case the difference between both the distances that is 100m and 5000m is 4900m that is, (5000-100) . On the other hand the difference between the distance in the second case is (10000-5000) that is 5000m.
By comparing both the cases we can see that there is a difference of 100. Thus, we can say as the runner covers a distance of 100m it takes 10.44 m/sec and 5000m at 6.60m/sec , the speed difference is more.
