La primera célula

The video explores the evolution of life, starting from a single ancestor shared by all living beings. It describes the early Earth's hostile conditions and the formation of a primordial broth from gases and ocean water. This broth, exposed to ultraviolet rays, led to chemical reactions forming complex molecules. These molecules eventually grouped into clusters, marking the beginning of life.

What is the estimated age of the first cell according to the video?

• 4000 years

• 5000 years

• 5000 million years

• 4000 million years

Which gases were primarily present in the early Earth's atmosphere?

• Oxygen and nitrogen

• Hydrogen, methane, and ammonia

• Carbon dioxide and oxygen

• Nitrogen and argon

What role did the sun's ultraviolet rays play in the early Earth?

• They cooled the planet

• They started chemical reactions

• They destroyed the atmosphere

• They provided oxygen

What are the essential organic compounds mentioned that are crucial for life?

• Proteins and lipids

• Carbohydrates and fats

• Amino acids and DNA

• Vitamins and minerals

How did the first life forms begin to sustain themselves?

• By absorbing sunlight

• By consuming other organisms

• By converting energy

• By photosynthesis
