About the glucose based on the given estimation
Introduction:
The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. Several parts of the body are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. The kidneys maintain homeostasis by removing wastes and excess water from the body and by maintaining the pH of the blood. The kidneys are the major excretory organ in the body. It is a bean-shaped organ that is involved in urine formation performs filtration of blood.
Answer to Problem 32A
Correct answer:
The correct answer is option (A) It is reabsorbed into the blood.
Explanation of Solution
Explanation/justification for the correct answer:
Option (A) It is reabsorbed into the blood. Kidneys filtered 180g/day glucose into the blood. 0g/day glucose is excreted that means no amount of glucose is excreted by the kidneys. 100% of glucose is reabsorbed by kidneys. So, the correct answer is option (A).
Explanation for incorrect answer:
Option (B) It is permanently filtered out of the blood. According to the given estimate, zero amount of glucose is excreted by kidneys. So, this is an incorrect option.
Option (C) It is treated in the kidney like creatinine. No, because creatinine is the by-product produced by our muscles which is removed by the kidneys from the blood and excreted in the urine and glucose is an essential substance required by our body for energy production. So, this is an incorrect answer.
Option (D) It is treated in the kidney like urea. Urea is a nitrogenous waste and glucose is an important substance. So, this is an incorrect answer.

- There is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance.
