Answer:-A coelom is a true body cavity, whereas a pseudocoelom is a false coelom that is not fully functional.

Several factors led to the rise of U.S. industrialization in the late 1800’s. New technologies like steam engines, railroads, and telegraphs made communication and transportation easier.

Workplace innovations, such as the assembly-line method of production, allowed these companies to produce goods on a mass scale.
In Piaget's theory of cognitive development, the use of metaphor and analogy is a sign of its formal operationality.
<h3><u>Describe formal operational.</u></h3>
Piaget's theory has four stages, the formal operational stage being the final and the fourth. Though Piaget does note that some people may never reach this stage of cognitive development, it starts around the age of 11 to 12 and lasts until adulthood.
The capacity to develop hypotheses and conduct systematic tests on them in order to find a solution to a problem characterizes the formal operational stage. In addition to being able to think abstractly, someone in the formal stage can comprehend the shape or structure of a mathematical problem.
