- b All living systems require constant input of energy.
- c Positive feedback mechanisms amplify responses and processes in biological organisms.
- d Organisms exhibit complex properties due to interactions between their constituent parts.
- e Mendelian genetics provides a basic understanding of the underlying causes of the pattern traits from parent to offspring.
5 Multiple choice questions
- Changes in genotype can result in changes in phenotype.
- A variety of intercellular and intracellular signal transmissions mediate gene expression.
- Cells communicate with each other through direct contact with other cells or from a distance via chemical signaling.
- Organisms must exchange matter with the environment to grow, reproduce, and maintain organization.
- Viruses reproduce and can introduce genetic variation into their hosts.
5 True/False questions
2.C.3. → Organisms use negative feedback mechanisms to maintain their internal environments and respond to external environmental changes.
4.C.2. → Variation in molecular units provides cells with a wider range of functions.
3.E.1. → Timing and coordination of several events are necessary for the normal development of an organism, and these events require regulation by multiple mechanisms.
4.B.1. → Interactions between molecules affect their structure and function.
2.B.3. → Eukaryotic cells maintain internal membranes that partition the cell into specialized regions.
