Look at the images of different rocks. Which two rocks have a fine-grained texture?

1 and 5
2 and 3
3 and 5
4 and 1

1 and 5

Explanation:

Image 1 and 5 actually show fine-grained textures of rocks.

Fine-grained textures actually indicates that magmas that are formed at or near the earth's surface cool rapidly. It's known that when magmas cool fast, they prevent very large crystals from growing. When hand samples of fine-grained rocks are taken, they appear homogeneous throughout the rock.

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
