Phase 1 of the creation of life on earth was the formation of small molecules containing carbon and hydrogen. phase 2 was the formation of self-replicating, information containing molecules. phase 3

The correct answer will be- formation of membrane

Explanation:

The three-stage origin of life theory suggests that life on Earth originated in three phases which are:

1. Phase I: The larger molecules formation began during this unsuitable earthly conditions full of volcanic eruptions and harmful gases underwater.

2. Phase II: The self-replicating molecule begins to form during this phase which contained the coding of life. The self-replicating molecule is known as the formation of the membrane.

3.Phase III: The formation of the membrane which help separate the outer environment from the inner environment was observed during this phase.

Thus, the formation of a membrane is the correct answer.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
