Rheumatoid arthritis is a disease that occurs when the body’s immune system starts attacking its own joint tissue. The symptoms are pain, inflammation, and swelling in the joints. Orthopedists (doctors who study bones) and immunologists (doctors who study the immune system) both work with patients who have rheumatoid arthritis. What is the difference between the orthopedists and immunologists who treat the disease?

Explanation:

Generally speaking people who have arthritis and see an orthopedist, are there because they seek information on how to lessen the pain of there joints and bones. Because of the pain they have, usually fingers and hands, even wrists are the worst parts. So, doing daily tasks, that most people consider easy are hard for them. But with immunologists, they visit them because they seek answers no how to become healthy and not run the risk of having any more health complications. And if you weren't aware, arthritis is an autoimmune disorder, so it causes your body to attack cells. That's why the pain is so bad. That could be a cause of which people go to see immunologists, or for other reasons!

I really hope this helped!

sorry, but you do not have posted the diagram.

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.
