Dr. riehm shows you an unlabeled tissue slide and says the tissue is very resistant to stretching, tearing, and compression. he then asks you what you can conclude about the structure of the extracellular matrix (ecm)

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
