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.

Which components of egg white are responsible for foam formation?

forsale [732]

Ovalbumin is the component of egg white which is responsible for foam formation.
Ovalbumin is the main protein component of the egg white and it is responsible for creating the foam structure when the egg whites are beaten. The physical stress caused by beating the egg white, causes the protein ovalbumin to denature and unfold. This denaturation, along with the mixing of air in the egg white, causes the formation of foam.

Answer:

A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>

Explanation:

G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
A cell cycle has two phases; interphase and M-phase.
During interphase the cell grows and in M-phase it divides.
G1 is the Gap between the M-phase and the S-phase.
G2 is the gap between the S phase and M phase.

DNA replication is confined to the S part of interphase.
Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
