Answer:
The option D is incorrect.
Explanation:
It is not necessary that the substance needs to get filtered out of the glomerulus to be present within the urine. Some of the substances may be present in the urine due to the secretion in the renal tubules post the filtration process in the glomerulus.
Like in the proximal tubule of the nephron, secretion results in the transport of some of the molecules out of the blood and within the urine. These secreted substances can be hydrogen ions, potassium ions, creatinine ions, and some kinds of waste components like drugs.
The conduction of substances from peritubular capillaries to the renal tubular lumen is termed as tubular secretion, and the process generally takes place by passive diffusion and active transport.
There are many factors to look for to determine a living organism. such as Nutrition, Reproduction, Sensitivity, Growth, Movement, Respiration, and Excretion.
TBut the most important that you can apply to all living organisms, even viruses are: Reproduction (it use the host to increase their number) and nutrition (it take energy from the host to replicate itself).
Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines
