Which theory is represented in this diagram? The theory that complex cells evolved after primitive cells engulfed bacterial cells that continued functioning
The theory that all living organisms share the same basic genetic components
The theory that organisms function best when their internal conditions are maintained within narrow limits
The theory that all living organisms are made of cells

The correct answer is A. The theory that complex cells evolved after primitive cells engulfed bacterial cells that continued functioning.

Explanation:

This diagram shows how a primitive cell or a cell containing only genetic material evolves into a complex cell with specific organelles such as chloroplast or mitochondria by engulfing or integrating other cells, especially prokaryotic cells that continue living in the primitive cell and become specialized organelles. This process supports the theory the evolution of cells was possible as simple cells engulfed bacteria because as the diagram shows the engulfed bacteria evolved into organelles that make the cell become more complex as there were specific structures in the cell for different functions.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
