Accepted Answer

Hello everyone and welcome to today's video so that we have that the summits are set of bilaterally paired blocks of blank that gave rise to muscle cells and connective tissue in the body. Let's go over our answer choices which involved three germ layers in our body in order to solve this problem. Well when we're looking at these germ layers, we need to just have a way to memorize what they each of them is going to be producing. The extra term is going to produce many external structures such as the skin, the eyes. And for example, this is not an external structure but we can think about it in that way, the brain, the end of them on the other way is going to be creating the linings of our internal organs. So for example, the lining of the pancreas was created by this and and then the Miss A term is going to be creating mostly everything else that we're going to be seeing so that some might or a set of bilaterally paired blocks of Miss a term that give rise to muscle cells, a connective tissue in the body. These are going to be created by the MS Ardern. So we're going to highlight that as a correct answer to our question. I really hope this video helped you and I hope to see you on the next
