Produce movement
Store genetic info
Bind/support body parts
Send neural signals
The Correct Answer is C
A. Produce movement: Producing movement is chiefly the role of muscle tissue working with the skeleton.
B. Store genetic info: Genetic information is stored in nucleic acids (DNA) within cells, not a primary role of connective tissue.
C. Bind/support body parts: Connective tissue (bone, cartilage, tendons, ligaments, adipose, blood) provides structural support, binds tissues, and protects organs.

B. Buffer: Buffers are substances (weak acid/base pairs) that resist rapid pH changes by neutralizing added acids or bases.
C. Enzyme: Enzymes are biological catalysts that speed chemical reactions; they do not function to stabilize pH.
D. Catalyst: A catalyst accelerates reactions without being consumed but does not inherently prevent pH shifts.
