4 i guess........................
When plates divide or separate it creates a divergent boundary.
I believe the correct response would be C. Plants acquire carbohydrates by producing them through the process of photosynthesis. This allows plants to then use the formed carbohydrates to build structural polymers, such as cellulose.
Some man-made fibres, too, are derived from naturally occurring polymers. For instance, rayon and acetate, two of the first man-made fibres ever to be produced, are made of the same cellulose polymers that make up cotton, hemp, flax, and the structural fibres of wood.
B and C are correct - A is incorrect as natural selection affects any generation of species. D is also incorrect as any species population change in an ecosystem inevitably affects another, even if it isn't a predator-prey relationship.
