How Old Are You? Well, Your Liver Is 3

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 remains consistent across ages, as shown by a study using radiocarbon dating. Meanwhile, a successful prediction of a volcanic eruption at Sierra Negra demonstrates advancements in natural disaster forecasting, though challenges remain due to variable volcanic behaviors.

What is the primary function of the liver that necessitates its ability to regenerate?

• Producing hormones

• Removing toxins

• Storing vitamins

• Digesting food

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

• X-ray imaging

• Radiocarbon dating

• Magnetic resonance imaging

• DNA sequencing

What was the conclusion about the regenerative capabilities of liver cells from different age groups?

• Liver cells have similar regenerative capabilities regardless of age

• Younger liver cells regenerate slower

• Older liver cells regenerate faster

• Liver cells lose regenerative ability with age

How long do human skin cells typically last?

• A year

• A month

• A week

• A day

Which volcano was used as a model for predicting eruptions?

• Mount Vesuvius

• Krakatoa

• Mount St. Helens

• Sierra Negra

What was the predicted time frame for the Sierra Negra eruption in 2018?

• July 10th to July 20th

• June 25th to July 5th

• June 15th to June 20th

• June 1st to June 10th

What unexpected factor influenced the actual eruption of Sierra Negra?

• A change in wind direction

• A minor earthquake

• A volcanic storm

• A sudden temperature drop
