Answer:
The correct option is option D which is 10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.
Explanation:
As the complete question is not given, the complete question is as below
Imagine that I start off with 10 molecules of oxaloacetate in a mitochondria. After running the TCA to generate 20 molecules of CO2, how many molecules of oxaloacetate will be left in the mitochondria (assuming oxaloacetate is being used only for TCA in these mitochondria)?
A) 30 – each molecule of CO2 generated corresponds to an increase of one OAA
B) 20 – every two molecules of CO2 generated corresponds to an increase of one OAA
C) 0 – two molecules of CO2 generated corresponds to one AcCoA used in the TCA; each AcCoA requires one molecule of OAA
D) 10 – one molecule of OAA is regenerated for every molecule of AcCoA used
Each cycle of TCA result in consumption of 1 Acetyl-Coenzyme (AcCoA) and 1 Oxaloacetate (OAA) molecule to give rise to 3 molecules of NADH and 2 molecules of CO2 per cycle. But at the end of each cycle, OAA molecule is regenerated. So the number of oxaloacetate(OAA) molecules remains unchanged.
Thus the correct option is option D which is 10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.

Answer:
The tropical rainforest is a hot moist biome where it rains every day year month etc, There is only a small amount of sunlight and rainfall that these plants receive. They usually adapt to their home environments! :)
Explanation:
All of the above, here's an explanation. The sun helps the water cycle due to evaporation which causes it to turn into a steam/gas. Now for wind, it's because the sun heats up the air and causes thermal energy which later turns into wind. And finally, weather, obviously the sun evaporates water which causes it to be rainy/drowsy.
