Question

select the correct answer. which sentence supports the statement that complex, multicellular organisms are made up of specialized cells that each perform different functions for the body? a. human liver cells make proteins that promote homeostasis that neurons do not. b. different species of bacteria have different shapes and structures to their cells. c. the dna in the cell nucleus of chimpanzees and humans are 98% identical. d. prokaryotes do not have nuclei, but they can still carry out the basic functions of life.

Explanation:

To support the statement about specialized cells in complex multicellular organisms, we analyze each option:

• Option A: Human liver cells and neurons are different cell types in a multicellular organism (human). Liver cells make specific proteins for homeostasis that neurons don't, showing they have different functions, which supports cell specialization.
• Option B: Bacteria are unicellular, so this is about different species of single - celled organisms, not specialized cells in multicellular organisms.
• Option C: This is about DNA similarity between two species, not about cell specialization within an organism.
• Option D: Prokaryotes are unicellular, and this is about their basic life functions without a nucleus, not about multicellular cell specialization.

Answer:

A. Human liver cells make proteins that promote homeostasis that neurons do not.
