A young woman experiences frequent urination with a burning sensation. Her urine contains many white blood cells and bacteria. There is no glucose or protein int the urine. What is th emost likely cause of these manifestations?

The correct answer is urinary tract infections.

Explanation:

An infection in any part of the urinary system, that is, the ureters, the kidneys, urethra, and the bladder is termed as a urinary tract infection. The majority of the infections take place in the urethra and the bladder. In comparison to men, women are more vulnerable to the condition. The urinary tract infections most of the times take place due to the invasion of the bacteria in the urinary tract via the urethra, these bacteria proliferate within the bladder and give rise to an infection.  

Some of the signs of the infections are a strong and persistent desire to urinate, passing of continuous but small concentrations of urine, at the time of urinating one feels a sense of burning, the urine looks cloudy in color due to the presence of WBCs and bacteria, urine smells strong and pain is experienced in the pelvic region of women.  

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
