Animals (5)

How does multicellularity in animals effect size and specialization?(2)

Biological macromolecule that provides external support and connects cells to one another

Key concept in biology

Larger organisms have relatively less skin, why is this important

Because larger animals can't get enough nutrients and gases to interior body across skin, what do they need?

Theory of how multicellularity occured (2)

What effect does infolding have on animals?

Choanoflagellates and collar cells are nearly indistinguishable, why is this important? (2)

During what major event did animals evolve from protist ancestor?

Mitotic division of fertilized eggs

2 layers

3 layers

Germ layers- what happens to the fertilized cell? From this product what is formed, and what it the final result? (3)

Hox genes (2)

Genes that control development by influencing the rate, timing and spatial pattern of change in an organism
