Contractile vacuoles maintain water balance by pumping excess water out of some single-called pond organisms . in multi-cellular humans , the kidney is chiefly involved in maintaining water balance . a: interference with nerve signals disrupts cellular communication and homeostasis withing organisms b: a disruption in a body system may disrupt the homeostasis of a single - celled organism c: structures found in single- celled organism can act in a manner similar to tissue and organs in multi-cellular organisms d: tissues , organs, organ systems work together to maintain homeostasis in all living things  i need with a quiz and i have 20 more questions if you will be willing to with it send me your email and i will send all the questions to you 

C: structures found in single- celled organism can act in a manner similar to tissue and organs in multi-cellular organisms

Explanation:

The question above shows a certain similarity in the function of structures of unicellular and multicellular organisms. As we can see, vacuoles are indispensable in balancing water within single-celled organisms. This function is similar to the function of the kidneys, in multicellular organisms, which is also responsible for the balance of water.

In addition, the function of the kidneys is, among others, to filter the blood to eliminate substances harmful to the body, such as ammonia, urea and uric acid. They also work to secrete substances important to our health. The kidneys receive blood from the renal arteries, branches of the aorta that come directly from the heart.
