When aldosterone is absent, Na+ reabsorption in the nephron is greatly reduced, and as 30-40g of sodium can be lost in the urine daily.
The answer is decreased.

The nephron (from Greek νεφρός - nephros, meaning "kidney") is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.
A nephron consists of a renal corpuscle and a renal tubule. The renal corpuscle includes the glomerulus and Bowman's capsule for filtration, while the renal tubule processes fluid from the glomerular filtrate.
It is called the Renal Cortex and is the layer found between the Reanl Capsule and Renal Medulla. It is the outer reagion of a kidney nad is colloured light red. Renal Cortex accomodates the Glomerular capsule, largest part of nephrone, arterioles, veins and capillaries. Most filtration processes occur in this part of Kidney.
From my experience, traces of protein in the urine can be considered normal. If you have concerns with protein in the urine, a dipstick urinalysis can be easily performed in the comforts of your own home. Test your urine each time you go to the restroom. If you have a trace of protein on 2 or more occasions in the same day, it make be worth asking your doctor about. Normal urine contains some protein, but when the protein level consistantly becomes above trace amounts, there could be an underlying kidney problem that should be addressed. Protein in urine can also be the result of excercise, emotional stress, cold or heat exposure, or fever.
Your body regulates pH through various buffering systems, mainly involving the kidneys, lungs, and chemical buffers in the blood. The kidneys excrete excess acids or bases, the lungs regulate CO2 levels to maintain pH, and chemical buffers in the blood help to minimize changes in pH by binding or releasing hydrogen ions.
