Shelllessculturesofchickembryos
This experiment allows you to observe the development of a chick embryo outside its shell. Cultured chicks are also more accessible for manipulation. Compare the extent of bone mineralization of control chicks to those in shell-less culture to determine if the egg shell provides a source of calcium.Shell-less culture set up at 3 days of incubation1. Squirt section of PVC pipe with 70% ethanol and allow to dry in lami......阅读全文
