• Spontaneous Generation

• Abiogenesis

NGSS.HS-LS1-6

The earliest form of life known on Earth was...

• Leafy Plants
• Bacteria
• Fossils
• Single-Celled Organisms

Tags

NGSS.MS-LS4-2

This gas was in high concentrations in the early atmosphere, and later condensed to form Earth's oceans. 

• oxygen
• carbon dioxide
• sulfur oxides
• water vapor

NGSS.MS-ESS2-4

What gas was most prevalent in Earth's early atmosphere?

• carbon dioxide
• oxygen
• water vapor
• sulfur oxides

What gas were we missing in Earth's early atmosphere?

• carbon dioxide
• oxygen
• water vapor
• sulfur oxides

All bacteria are

• prokaryotes

• eukaryotes

DNA is located in the nucleus

• prokaryotes

• eukaryotes

Do not have a nucleus

• prokaryotes

• eukaryotes

Eukaryotes have

• a real "true" nucleus

• no membrane bound organelles

• no nucleus

Eukaryotic cells are

• the smallest of cells

• those without DNA inside of a nucleus

• more complex than prokaryotic cells

• found only making up multicellular organisms
