Question

small molecules are combined to form large molecules by the life function of

1. regulation
2. excretion
3. transport

4 synthesis

Explanation:

• Regulation: This involves controlling and coordinating body functions, not combining small molecules into large ones.
• Excretion: It is about removing waste products from the body, not molecule synthesis.
• Transport: Deals with moving substances within the body, not building large molecules from small ones.
• Synthesis: This life function specifically refers to combining small molecules (like monomers) to form large molecules (like polymers). For example, amino acids (small molecules) are combined to form proteins (large molecules) through synthesis.

Answer:

1. synthesis
