The problems the girl exhibits when eating fruit is most likely due to elevated levels of fructose-1-phosphate in liver cells
Define Hereditary fructose intolerance (HFI).
Fruit sugar fructose and its precursors cannot be digested in people with hereditary fructose intolerance (HFI). The accumulation of fructose-1-phosphate in the liver, kidney, and small intestine is caused by a lack of activity of the enzyme fructose-1-phosphate aldolase.
The patient has HFI, which is due to a mutation in aldolase B. Sucrose would still be cleaved by sucrase, thus it would not increase in the stool. Fructose would not be metabolized normally, therefore it would be elevated in the blood and urine. Aldolase B would not cleave fructose 1-phosphate, thus its levels would be elevated and the product, glyceraldehyde, would not be produced.
HFI patients frequently grow to dislike fruit and sweets intensely. After consuming fructose-containing foods, they may experience symptoms like excruciating stomach pain, vomiting, and low blood sugar.

That would be the end of that species in one generation.
Answer:
B) agility
that is the one that makes the most sense
Answer: You should list the answer choices, however if you cannot, I will list all of the advantages of the lactic acid system:
- Provides more sustained high-intensity energy for between 10 and 180 seconds.
- Can work both anaerobically (without oxygen) and aerobically (with oxygen).
- There is a huge amount of glycogen stored in the muscles and liver which can be made available for energy.
- Fewer reactions than the aerobic energy system are needed to produce energy so it is faster (but not as fast as the PC system).
- It is more efficient than the ATP-PC system as the lactic acid system resynthesises two molecules of ATP as opposed to just one that the ATP-PC manages.
