Why do dead whales EXPLODE? | The Infamous Japanese Exploding Whale

The video explains the phenomenon of exploding whales, focusing on the biological processes that occur after death. It discusses how gas buildup, primarily methane, results from bacterial overpopulation in large organisms like whales and elephants. The video also covers the chemical reactions that produce foul-smelling compounds and the conditions leading to explosive pressure release. The phenomenon is unique to large organisms due to their significant biomass, which allows for substantial gas production.

What is the primary biological reason for the explosion of a whale after death?

• The whale's skin becomes too tight.

• Gas buildup due to bacterial activity.

• The whale's bones expand.

• The whale's heart continues to pump blood.

What happens to carbon dioxide inside a deceased organism?

• It solidifies into ice.

• It converts into acid.

• It turns into oxygen.

• It evaporates into the air.

Which of the following is a result of cell membrane degradation in a dead organism?

• Cell contents are expelled.

• The organism becomes more rigid.

• The organism becomes lighter.

• The organism changes color.

What role do bacteria play in the decomposition of a whale?

• They stop the decomposition process.

• They produce gases like methane.

• They prevent gas buildup.

• They make the whale heavier.

What are cadaverine and putrescine responsible for in a decaying body?

• The foul smell.

• The body's rigidity.

• The body's weight loss.

• The body's color change.

Why do smaller organisms not experience the same explosive phenomenon as whales?

• They have less biomass for gas production.

• They live in different environments.

• They decompose faster.

• They have stronger skin.

Which gas is primarily responsible for the pressure buildup in a decaying whale?

• Hydrogen

• Methane

• Nitrogen

• Oxygen
