In its excretory role, the urinary system is primarily concerned with the removal of wastes from the body. In its excretory role, the urinary system is primarily concerned with the removal of wastes from the body. carbon-containing nitrogenous

The answer is NITROGENOUS WASTE.

Explanation:

The urinary tract  filters wastes and water from the blood, and eliminates them from the body.

UREA which is a nitrogenous byproduct of the decomposition of protein metabolism in mammals, is also released into the blood stream and to the tubes, after being broken down by the LIVER. All waste mixes with the filtrate to form urine

Urine is then collected in a duct and excreted through the bladder.

The correct answer to fill in the blank is: nitrogenous.

Explanation:

The excretory role of the urinary system consists of eliminating metabolic wastes, which are leftovers from processes such as cellular respiration.

A big part of these wastes are nitrogenous compounds like ammonia (which acidifies the urine), uric acid, urea, and creatinine. Nitrogenous wastes are produced from protein metabolism.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
