Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorpion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for two weeks as they grow big enough to take care of themselves. The skin cells of a scorpion organize together to make a hard covering called a carapace, which helps protect the scorpion. Which term names a group of similar cells working together? Question 2 options: Organism Tissue Organ System

The correct answer is - tissues.

The tissue is an organization of the cells to work together to perform a specific type of function in an individual organ or body system of an organism. The skin cells of the scorpion also organize together to play the role of hard covering that helps the scorpion to be protecting.
