Both the nervous and endocrine systems control body functions. how are they similar and dissimilar in the way they work, types of structures served, and speed of action?

Similarity

Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.

Difference

1. nervous  system uses  electrical impulses (neural)for signaling while endocrine system  uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.

2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.

Explanation:

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
