- a Cells communicate with each other through direct contact with other cells or from a distance via chemical signaling.
- b Cell communication involves processes resulting from evolution that are shared common features.
- c Timing and coordination of several events are necessary for the normal development of an organism, and these events require regulation by multiple mechanisms.
- d Mendelian genetics provides a basic understanding of the underlying causes of the pattern traits from parent to offspring.

5 True/False Questions
3.E.1. → Organisms exchange information with each other in response to internal changes and external cues, which may change behavior.
2.A.1. → All living systems require constant input of energy.
4.A.4. → The subcomponents of a biological polymer and their sequence determine the properties of that polymer.
4.A.3. → Organisms exhibit complex properties due to interactions between their constituent parts.
4.A.2. → Organisms capture, use, and store energy in biological processes such as growth, reproduction and maintaining homeostatic processes.
