Because he/she needs to store large quantities of energy that he/she would require for the race. Pasta mainly consists of wheat which a carbohydrate. carbohydrates are primary source of energy in the body. once an athlete consumes pasta, starch in the wheat will digested to produce excess glucose which will be stored in form of glycogen in the live by the help of hormone insulin. during the race day, when an athlete uses all glucose in the blood, glycogen is converted to glucose through the help of hormone glucagon. glucose is transported to skeletal muscle cells where it is converted to energy.
Compaction and cementation
<span>Multiple mutations in the DNA over several reproductions lead to mutations that give rise to malignancies. Cancer cells reproduce at an accelerated rate and do not die in the same time frame as normal cells, resulting in masses of cells (tumors).</span>
These are some ideas:
→ It's an algae, so it will occur in water.
