What is the one main difference in how unicellular organisms and multicellular organisms maintain homeostasis.

Only unicellular organisms have specialized cells that work to maintain homeostasis

Only multicellular organisms have specialized cells that work to maintain homeostasis

Only unicellular organisms have to balance factors such as water and temperature

Only multicellular organisms have to balance factors such as water and temperature

Answer: Option B

Explanation:

The organism that are made of single type of cell is known as unicellular organism. Their body is simple and homeostasis is maintained by vacuoles. There is no specific specialized cell found in the body of unicellular organism that maintains homeostasis.

The multicellular organism have specialized cells that is equipped to perform homeostasis. The cells of the body maintain the internal temperature, acidity, pH and other metabolic activities.

The correct answer is option B

The second answer is correct.

The first is incorrect because a unicellular organism is composed of just one cell. By definition, it cannot have specialized cells.

The final two answers are incorrect because all organisms - unicellular and multicellular - need to balance factors such as water and temperature.
