The Origin of Eukaryotic Life

What makes the origin of eukaryotic life a unique event in Earth's history?

• It happened multiple times.

• It occurred only once in nearly 4 billion years.

• It was a common event in evolutionary history.

• It was not significant for the development of life.

How are eukaryotes fundamentally different from prokaryotes?

• Eukaryotes are complex and share a common ancestor with all complex life.

• Eukaryotes are built from the same basic components as prokaryotes.

• Eukaryotes have a common ancestor with bacteria.

• Eukaryotes are single-celled organisms.

Why couldn't prokaryotes evolve into complex organisms like eukaryotes?

• They had too much genetic diversity.

• They were too large to evolve further.

• They couldn't produce enough energy due to surface area limitations.

• They lacked the necessary genetic material.

What was the significant event that led to the formation of the first eukaryote?

• A bacterium evolved into a eukaryote.

• An archaean cell absorbed a bacterium and formed a symbiotic relationship.

• Two prokaryotes merged to form a eukaryote.

• A virus transformed a prokaryote into a eukaryote.

What role did mitochondria play in the evolution of eukaryotes?

• They stored genetic information.

• They provided structural support.

• They were responsible for photosynthesis.

• They produced ATP, allowing eukaryotes to grow and specialize.

How do mitochondria support the theory of endosymbiosis?

• They have a linear DNA structure.

• They contain their own circular DNA similar to prokaryotes.

• They do not produce ATP.

• They are found only in plants.

What evidence supports the idea that eukaryotes are a genetic mashup?

• Eukaryotes have no genetic material from prokaryotes.

• Eukaryotes have genes traceable to both bacteria and archaea.

• Eukaryotes have a single origin of genetic material.

• Eukaryotes evolved independently of other life forms.

What is the significance of the eukaryotic origin event?

• It limited the diversity of life forms.

• It allowed life to overcome energy constraints and diversify.

• It was a minor event in evolutionary history.

• It only affected plant life.

How much ATP does a single human cell use per second?

• 20 million ATP tokens

• 1 million ATP tokens

• 5 million ATP tokens

• 10 million ATP tokens
