What is true about Maxwell's equations? (Select all that apply). The magnetic flux passing through a surface is always zero. Displacement currents are created by a change in the electric field flux passing through a surface. The circulation of the B field around a closed path must be zero if the current enclosed by the path is zero. A change in magnetic flux passing though a surface will create an emf along the boundary of that surface.

Joni has noticed that she has been having some serious problems lately - her legs and arms have become thin and “stick like” - but her face is much rounder. She’s also noticed that her abdominal region is rounder, despite the daily abdominal crunches, and the backs of her shoulders appear larger and more “fatty.” Joni is likely to have high levels of which hormone?
