Liver Regeneration and Eruption Prediction

The video discusses two main topics: the regenerative capabilities of the human liver and the prediction of volcanic eruptions. The liver's ability to regenerate is explored through a study using radiocarbon dating, revealing that liver cells maintain regenerative capabilities throughout a person's life. The second topic covers the prediction of volcanic eruptions, specifically the Sierra Negra volcano, using real-time data models. The video concludes with a sponsor message from Shopify.

What is the main function of the liver that necessitates its regenerative ability?

• Removing toxins

• Digesting food

• Producing hormones

• Storing vitamins

What method did researchers use to determine the age of liver cells?

• Magnetic resonance imaging

• Radiocarbon dating

• X-ray imaging

• DNA sequencing

What was the age range of the liver donors in the study?

• 20 to 84 years

• 40 to 100 years

• 10 to 60 years

• 30 to 90 years

What did the study reveal about the regenerative capabilities of liver cells in older donors?

• They are slightly reduced

• They are significantly reduced

• They are enhanced

• They are the same as in younger donors

What natural disaster were researchers able to predict using a model?

• Tsunami

• Volcanic eruption

• Hurricane

• Earthquake

Which volcano was used as a model for predicting eruptions?

• Mount Vesuvius

• Sierra Negra

• Mount St. Helens

What was the predicted time frame for the Sierra Negra eruption?

• June 15th to June 25th

• July 1st to July 10th

• June 1st to June 10th

• June 25th to July 5th

What was the actual date of the Sierra Negra eruption?

• June 24th
