Connective Tissue Fibers. Let's focus on the fibrous material created by fixed cells in connective tissue. Tissue fibers are classified based upon the type and 'weave' the fibers create. There are different types of weave, just like we have different types of fabric which make up our clothes.
The most difficult college to get into in the country, the California Institute of Technology, accepts less than one student for every 11 applicants.
The University of Pennsylvania accepted 3,697 from 37,267 applicants, at a rate of 9.9%. Yale University admitted 1,963 of 30,237 applicants, or 6.49% of applicants. Cornell University accepted 6,234 students from 41,907 applications, or 14.9% of applicants. Therefore, Cornell is the easiest Ivy to get into. However, that doesn't account for differences in intra-school applications. For example, at UPenn, it's much harder to get into Wharton than the College.
