Explanation:

The prefix "endo -" is a common prefix in biological and medical terminology. For example, "endocytosis" is a process where cells take in substances by engulfing them (entering the cell). Another example is "endoderm" which is the inner layer of cells in an embryo. These examples show that "endo -" is related to the concept of "entering" or being "inside".
