Question
**Transcription and Explanation for Educational Website** The data presented in the image suggests that there is a correlation between telomere length and a bird's lifespan. **Graph 1: Telomere Length Over Time** - **X-axis:** Age (years), ranging from 0 to 7. - **Y-axis:** Telomere length (T/S ratio), ranging from 0.5 to 1.1. - **Observation:** As the bird ages, the telomere length decreases. There is a noticeable decline in the T/S ratio from younger to older ages, suggesting that telomeres shorten over the bird's lifetime. **Graph 2: Lifespan Correlation with Telomere Length** - **X-axis:** Telomere length (ln(T/S) ratio), ranging from -1.0 to 1.5. - **Y-axis:** Lifespan (years), ranging from 0 to 9. - **Observation:** There is a positive trend, where longer telomeres correlate with a longer lifespan. This indicates a positive correlation between lifespan and telomere length. **Conclusion Options Explained:** 1. Telomeres shorten over a bird's lifetime. 2. NO correlation between lifespan and telomere length. 3. Negative correlation between lifespan and telomere length. 4. Telomeres lengthen over a bird's lifetime. (Selected option) Given the data provided in the graphs, it is evident that shorter telomeres over time are associated with a decrease in measured telomere length, while longer telomere lengths are linked to extended lifespans.
