Question

**URGENT PLEASE HELP!!**

One challenge of tissue engineering is to ensure that the cells grow into the correct shape. To facilitate the growing of the cells, engineers use what?

A. Biocompatible materials
B. Nanotubes
C. The engineering process
D. Scaffolds

Answer 1

(D) Scaffolds

Step-by-step explanation:

Scaffolds are small structures around which cells grow according to Apex. They form a shape for the cells to develop.

The engineering process refers to the steps scientists take to conduct an experiment, biocompatible materials help for not damaging the body when prostheses are used, and nanotubes are from a completely different unit.
