biol+2+endocrine+system+puzzles

Insert you picture puzzles in the space below. you will need to have saved your work as a picture file, then load it and insert it. I have placed another one to inspire you all! Please wait a day or two before writing an answer next to a puzzle (maximum of two, so that all have an opportunity). If some remain unsolved by the Friday, then anyone can go for it and solve all.
