This box is the âfeeder boxâ â where the worms will live and feed. Half fill the feeder box with the worm bedding. Make sure your bedding is moist but not wet. If you are using dry materials like straw or shredded paper, wet them first and then squeeze out any excess water.
Causes. There is no known single cause for autism spectrum disorder, but it is generally accepted that it is caused by abnormalities in brain structure or function. Brain scans show differences in the shape and structure of the brain in children with autism compared to in neurotypical children.
Certain known genetic disorders are associated with an increased risk for autism, including Fragile X syndrome (which causes intellectual disability) and tuberous sclerosis (which causes benign tumors to grow in the brain and other vital organs) â each of which results from a mutation in a single, but different, gene.
