One method of rating complexity in scientific disciplines is with respect to the number of variables that are involved in experiments. Using this method, which of the following disciplines is the most complex? a. Mathematics,
b. Anatomy,
c. Chemistry,
d. Sociology

a. Mathematics

Explanation:

There are various scientific studies and their complexity is different from each other. The one study might be difficult for one student but the other student who has interest in the particular subject might find it easy and interesting. Mathematics is the study which involves lot of variables which increase its level of complexity. The scientist may stuck in solution for years due the complexity of the multiple variables.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

the answer is 75.0%.
