Question

question 8 of 10
how do scientists think protobionts formed?
a. archaea reproduced with bacteria.
b. cell - like structures formed from molecular bubbles.
c. eukaryotes evolved due to natural selection.
d. prokaryotes absorbed other prokaryotes.

Explanation:

Protocells or protobionts are thought to be the precursors of living cells. They are cell - like structures. One of the hypotheses for their formation is that they formed from molecular bubbles (such as coacervates or microspheres). Archaeal - bacterial reproduction (A) is not related to protobiont formation. Eukaryote evolution (C) and prokaryote - prokaryote absorption (D) occur after the formation of more complex cells, not in the context of protobiont formation.

Answer:

B. Cell - like structures formed from molecular bubbles.
