Question:
During embryo development which of the following germ layers differentiates to form the muscles?
A
Mesoderm.
explanation
The three primary germ layers of the embryo include: the ectoderm, endoderm, and mesoderm. The introderm is not an actual term in biology. The endoderm forms the gastrointestinal tract, the lungs, the pharynx and parts of the urinary system. The ectoderm forms the skin (or epidermis) and related structures like hair and nails, as well as the brain and spinal cord. It is the mesoderm that differentiates during embryonic development to form connective tissues like cartilage, bone, and muscle.[Life Science]

Ive had this app for a while now and I seem to be having trouble loading the English section. When I click on “Reading” on the home page, it just takes me to a white screen where nothing loads (except the ads, of course). Please fix. I’d like to continue studying. And now the actual practice teas test won’t work. It won’t let me change the number of test questions from 0. So I literally can’t even see any questions. Please please update. There was an update but to my surprise, these two problems I’m having are still a problem. The reading section is still not loading and the Teas questions are still at 0 and cannot be changed so how am I actually supposed to be able to practice for my teas test next month if your app isn’t working properly
