Question

Help me please

1. What is homeostasis?


2. What roles do bacteria play in the environment?


3. Compare and contrast homeostasis in single-celled organisms and multicellular organisms.



4. Describe the levels of organization in multicellular organisms.



5. What is a cell receptor?

Answer 1

1. the tendency of interdependent elements to maintain a relatively stable equilibrium, especially as maintained by physiological processes

2. Their tireless labor completes the cycling of nutrients such as carbon, nitrogen, and sulfur. Without the activity of decomposers, the organic carbon in the form of dead and rotting organisms would quickly deplete the carbon dioxide in the atmosphere.

3. Unicellular organisms grow, respond to their surroundings, transform energy, and reproduce to maintain homeostasis. Multicellular organisms' cells specialize in specific tasks and communicate with one another to maintain homeostasis. To maintain homeostasis, all body systems collaborate.

4. The cell is the most fundamental unit; groups of similar cells form tissues; groups of different tissues form organs; groups of organs form organ systems; and cells, tissues, organs, and organ systems combine to form a multicellular organism.
