Our AP Biology unit 4 practice test explores how a cell communicates within itself and with nearby cells. This unit takes special note of key examples of cell communication. It also emphasizes cellular communication pathways that regulate the cell cycle.
Prepare to dive deep into the inner workings of cells! In this unit, you'll learn about how cells communicate with one another, how cells divide, and how problems can arise when these processes go wrong.
Identify a message communicated by direct cell-to-cell contact. What occurs during this process? Immune cell (b-cell activation: b-cells bind to an infected cell).

Overview. Investigating the Cell Cycle. Prompt. Figure 1. In order for a multicellular organism to grow or a unicellular organism to reproduce, cells must divide. In order to create a near-perfect replica, cells must first copy their DNA and then evenly divide up this DNA between the two daughter cells produced.
