When placed at the perimeter of a maze with food in the center, the plasmodial slime mold Physarum polycephalum explores the maze, retracts branches from dead-end corridors, and then grows exclusively along the shortest path possible to the food. How does Physarum do this? One theory is that it leaves behind slime deposits—an externalized 'memory' that 'reminds' it not to retry dead ends. Propose an experiment that would test whether the coating of extracellular slime changed the speed at which the slime mold moved across the substrate.

Hello everyone and welcome to today's video. So, slime molds are like blank in their army Boyd plus morial stage and are similar to blank in their abundance pore formation stage. So these organisms are divided into two stage and each stage represents a different group of organisms. So let's quickly break down each stage in terms of their characteristics so that we can under this better and solve the problem. So the first stage which is here is also called the growth stage. And in this stage they lack cell walls. They have Ami Boyd movement. That is what is called the amyloid plaque memorial stage. But they also ingest particular nutrients. So because of this they are very similar to protozoa which have similar characteristics to this. On the other hand, they also have the provocative stage which is when they reproduce which is here is the formation of sports stage. And here they develop. As for India and this is how they are able to produce sports. However, this is very prevalent in fungi. So these are the two groups of organisms that each stage is more like. So looking at our answer choices, the answer choice that has these organisms in that particular order is going to be answer choice C. So, slime modes are like protozoa in the Army Boy plus morial stage and are similar to fungi in the abundant sport formation stage. That's going to be the final answer to our problem. I really hope this video helped you
