Answer:

A hypothesis that is not possible, or has less strength, to explain how life arose on Earth is that it originated from cells that were delivered by meteorites from outer space (option D).

Explanation:

Although it is a hypothesis that has scientific foundations to be considered, the origin of life coming from organic molecules or cells from space -called Panspermia- has not been completely proven because:

  • It provides information on the origin of cells or organic matter, but it doesn't specify how life was formed from them.
  • It does not resolve the question of how a cell could withstand a journey through space or endure the high temperatures when a meteorite entered the primitive atmosphere.

These arguments make the hypothesis of the arrival of the first cells from outer space the least accepted today.

<h3>What are Gram stain negative bacteria?</h3>

Gram-negative bacteria have cell walls with thin layers of peptidoglycan and high lipid content.

This causes them to appear red to pink under a Gram stain.
