|
3 function arthropod exoskeletons and vertebrate endoskeletons have in common |
protection support site for muscle attachment |
|
|
relationship btwn molting and growth in arthropods |
after old exoskeleton is shed, new larger one is secreted so animal has room to grow |
|
|
medullary cavity |
location of yellow marrow |
