question 7 of 10
this diagram represents levels of organization within a multicellular
organism. what does the x represent?
x
cell
organelle
water
hydrogen
a. molecule
b. tissue
c. macromolecule
d. atom

Explanation:

To determine what X represents, we analyze the levels of organization in a multicellular organism. The smallest unit here is Hydrogen (atom), then Water (molecule), then Organelle, then Cell. The level above Cell should be Tissue (since cells group to form tissues, tissues to organs, etc.). The options: Molecule is smaller than cell (Water is a molecule), Macromolecule is also smaller, Atom is the smallest (Hydrogen is an atom). So X, being a level above Cell, must be Tissue.

Answer:

B. Tissue
