1. Which is an example of the correct organizational hierarchy for a wolf?
Answer: B
DNA, blood cell, muscle tissue, heart, circulatory system, wolf
This sequence illustrates the correct organizational hierarchy for a wolf, progressing from the molecular level of DNA to the organism level represented by the wolf itself.
A) Muscle tissue, blood cell, DNA, organ, circulatory system, wolf
This option incorrectly orders the components, starting with muscle tissue rather than the foundational level of DNA. Additionally, it places organ and circulatory system after these components, disrupting the proper hierarchy.
B) DNA, blood cell, muscle tissue, heart, circulatory system, wolf
This choice correctly follows the organizational hierarchy, starting from DNA, which forms the basis of biological structure, followed by blood cells, muscle tissue, the heart, and the circulatory system, culminating at the organism level with the wolf.
C) Circulatory system, DNA, muscle tissue, blood cell, heart, wolf
This option is also incorrect as it begins with the circulatory system, which is a higher organizational level than DNA. The sequence disrupts the logical progression from molecular to systemic levels.
D) Blood cell, organ, circulatory system, muscle tissue, DNA, wolf
This choice fails to follow the appropriate hierarchy, as it starts with blood cells and incorrectly places DNA at a higher level than muscle tissue. The arrangement does not reflect the proper biological organization.
Conclusion
Option B is the only answer that accurately represents the hierarchical order of biological organization, beginning with DNA and culminating in the wolf as an organism. The other options misplace fundamental biological units or disrupt the logical progression, demonstrating a misunderstanding of the organizational structure in biological systems.
