The ideal supply of building blocks for a weightlifter's body would be protein.
The body requires three macromolecules: carbohydrates, proteins, and fats. Protein is a component of cell growth. The weightlifter has to bulk up, and the majority of the protein that makes up muscle fibre is protein. In actuality, an animal's meat or muscle is its primary source of protein.
Living things contain chemical molecules called proteins. They perform several different tasks, such as organizing, transportation, and defence. A protein can have up to four different structural levels and is made up of chains of amino acids. Examples of particular proteins are collagen, insulin, and anticorps.
Thus, the ideal supply of building blocks for a weightlifter's body would be protein.

Your question is incomplete, most probably the complete question is:
A weight lifter needs to build muscle mass. which macromolecule would be the best source of building materials for the weight lifter's body?
Answer:You would earn .05 x $500 or $25 over that time period.
Answer: The answer is 314.28 cm² (approx.).
Step-by-step explanation: Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm.
We need to find the area 'A' of the circular cross-section of the pipe.
Given, diameter of the circular section is
So, the radius of the circular cross-section will be
Therefore, cross-sectional area of the pipe is
Thus, the answer is 314.28 cm² (approx.).
