Question

what is a process that ensures the cell is attached to some type of substrate? pdgf action anchorage dependence cyclin dependence density dependence

Explanation:

• PDGF (Platelet - Derived Growth Factor) action is related to cell growth and proliferation, not cell - substrate attachment.
• Cyclin dependence is related to the regulation of the cell cycle, not cell - substrate attachment.
• Density dependence is related to cell - cell interactions and how cell growth is regulated by cell density, not cell - substrate attachment.
• Anchorage dependence is the property of cells that they must be attached to a substrate (such as the extracellular matrix in multicellular organisms) to survive, grow, and divide.

Answer:

Anchorage dependence
