- a Organisms exhibit complex properties due to interactions between their constituent parts.
- b Cell membranes are selectively permeable due to their structure.
- c Eukaryotic cells maintain internal membranes that partition the cell into specialized regions.
- d Organisms exchange information with each other in response to internal changes and external cues, which may change behavior.
- e Viruses reproduce and can introduce genetic variation into their hosts.
5 Multiple choice questions
- Signal transduction pathways link signal reception with cellular response.
- Cell communication involves processes resulting from evolution that are shared common features.
- Growth and dynamic homeostasis is maintained by the constant movement of molecules across membranes.
- A variety of intercellular and intracellular signal transmissions mediate gene expression.
- Timing and coordination of several events are necessary for the normal development of an organism, and these events require regulation by multiple mechanisms.
5 True/False questions
2.C.1. → Variation in molecular units provides cells with a wider range of functions.
2.D.3. → Organisms constantly respond to changes in their external environments.
2.A.3. → Organisms must exchange matter with the environment to grow, reproduce, and maintain organization.
2.C.2. → Organisms use negative feedback mechanisms to maintain their internal environments and respond to external environmental changes.
3.A.1 → Cells can be activated, produce new products, and retain their activated state through gene regulation
