The organic matter, or hydrocarbon raw material, is derived primarily from petroleum and natural gas.
Over 90% of the organic chemicals are produced from petroleum and natural gas routes nowadays. Even though the manufacturers search for alternatives because of the prices of the petroleum and natural gas, and look to replace them little by little, still these two are by far the dominant ones.

Comparison of the excretory system of a rat, frog and human
yaroslaw [1]
In general, the function of the excretory system is,  removal of nitrogen waste products from the bloodstream and transport out of the body through urine. It maintains the balance of fluids and electrolytes, control of red blood cells, regulation of blood pressure and also the formation of red bone marrow.
In humans, the excretory system is responsible for removing waste from the body. Metabolic waste is being removed from the blood and an appropriate amount of water nutrients and water and salt are being retained.
In frogs, the excretory system consists of a pair of ureters, kidney pairs, cloaca, and urinary bladder. Frogs take in liquid waste from kidney which removes wastes and then the extra water becomes urine which then it is collected in the urinary bladder through ureters.
The urinary bladder is present in ventral to return then both open into the cloaca.

Oxygen and Carbon Dioxide exchange as a result of the interaction of which two body systems
miskamm [114]

Answer:

4

Explanation:

The circulatory system includes the blood that has picked up the carbon dioxide from all of the respiring tissues and who also delivered oxygen to them to continue respiring.

The blood will then reach the lung where the carbon dioxide that the tissues released is exchanged for oxygen in the alveoli.

* Blood cells isn't an organ system which makes 1 incorrect.

* Digestive system will in no way bring the blood to the lungs or away from it. This is the circulatory system's job. So 2 is incorrect.

*Lastly, lungs are organs and the question asks for organ systems. So 3 is incorrect.
