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 (a type of specialized cell in a multicellular organism) make specific proteins for homeostasis that neurons (another specialized cell) do not. This shows different specialized cells have different functions, supporting the statement.
• Option B: Talks about different bacteria (unicellular organisms) having different cell shapes/structures, not about specialized cells in multicellular organisms.
• Option C: Compares DNA of chimpanzees and humans, not about cell specialization in multicellular organisms.
• Option D: Discusses prokaryotes (mostly unicellular) lacking nuclei, not about specialized cells in multicellular organisms.

Answer:

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