Question

As a frog embryo develops, the neural tube forms from ectoderm along what will be the frog's back, directly above the notochord. To study this process, a researcher extracted a bit of notochord tissue and inserted it under the ectoderm where the frog's belly would normally develop. What can the researcher hope to learn from this experiment? Predict the possible outcomes. What experimental control would you suggest?

Accepted Answer

Hello everyone and welcome to today's video. So during organogenesis blank is a process that results in the formation of the central nervous system. Let's go over answer choices so that we may solve the problem. Beginning by answer choice, a differentiation. This is the process by which a cell specializes into a specialized cell that is going to be present in the liver, in the pancreas or in the brain. It really depends where it is needed because of this. This is not going to create the central nervous system. So we're going to cancel it out. Then we have blast elation and this is a process that creates a blast tula. We're not going to have a central nervous system here yet. So we're going to cancel it out. Then we have gas relation and this creates the gastro here. This is going to help line the miss a dream, ectodermal and in the term layers in what we have up until up until that point. However, here we don't have a central nervous system yet. So we're going to be canceling this out as well. And this leaves us with near relation. If you see the word near relation, this looks a lot like neuron and it involves the creation of this narrow plate and this neuro plate is going to be involved in the formation of this central nervous system because of this, this is going to be our correct answer choice and the final answer to our question. I really hope this video helped you and I hope to see you in the next one
