John has been studying classification in class. He learned that Aristotle was the first to classify organisms. Aristotle classif
ied organisms into two main groups with three subgroups under the two main groups. John was confused by the examples in the subgroups below because some were in more than one subgroup. 
Based on the evidence, formulate an explanation for why Aristotle’s classification system was too general in classifying organisms.
The system Aristotle created did not allow organisms to be classified into small subgroups where they’d be able to be varied and differentiated, rather, he placed them in plants and animal groups (?) where there allowed to be no classification rather than the basics that included phenotypes primarily. Therefore, his classification system was too general in the sense that in only classified based off general phenotypes rather than sub qualities within the organism.
Blood cells are a lot smaller than nerve cells and have a disc-shaped structure, both great traits for moving quickly through small spaces. Their disc shape also provides them with a big surface where lots of oxygen can enter the cell.
