22. Different species within a phylum all have the same basic .
(1 point)

Different species within a phylum all have the same basic characters, anatomical and functional integrity, common ancestry.

Explanation:

The animals having same phylum but different species have similar basic structural pattern. That means the anatomical features are constructed on the same ground plan. This individuals have similar functional integration. All animals of a phylum work as a functional machines with similar functional integration.

Another important feature is they have common ancestry. Evolutionary study have confirmed all members of  a similar phylum have been derived directly or indirectly from a common primitive ancestry.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
