Final answer:
The half-life of Albumin, a plasma protein synthesized in the liver, is approximately 20 days, fitting within the 10 to 100 days range in the Half Life Guide.
Step-by-step explanation:
The half-life of albumin can be accurately determined by examining its rate of decay in the body. The half-life is the time required for the amount of a substance to reduce to half its initial value. Albumin, being a plasma protein synthesized in the liver, has a half-life that is a critical factor in assessing metabolic functions and nutritional status.
According to the provided information, the half-life of Albumin is not less than a day, nor does it lie within 1 to 10 days. Instead, it fits in the range of 10 to 100 days as per the Half Life Guide. Considering the specific educational references provided, it is established that the half-life of Albumin is approximately 20 days, marking option 4 as the correct answer.
