Question

1. the function of which human organ is most like the cell walls of bacteria? a. skin b. liver c. heart 7. all living organisms must maintain homeostasis in order to survive. which statement best describes one way humans maintain homeostasis? a. temperature is regulated by giving off carbon dioxide. b. water content is regulated by sweating. c. temperature is regulated by sweating. 8. which conclusion is best supported by the presence of ribosomes in prokaryotes and eukaryotes? a. ribosomes have different functions in prokaryotes and eukaryotes. b. ribosomes developed independently inside prokaryotes and eukaryotes. c. both prokaryotes and eukaryotes make proteins to perform life functions.

Explanation:

1. The cell - wall of bacteria provides structural support and protection. Among human organs, the skin also serves as a protective barrier, similar in function to the cell - wall of bacteria.
2. Homeostasis involves maintaining a stable internal environment. Sweating is a mechanism to regulate body temperature, so temperature is regulated by sweating.
3. Ribosomes are present in both prokaryotes and eukaryotes and are involved in protein synthesis, which means they have similar functions in both types of cells.

Answer:

1. A. skin
2. A. Temperature is regulated by sweating.
3. C. Both prokaryotes and eukaryotes make proteins to perform life functions, indicating ribosomes have similar functions in both.
