Which system serves as the interface between the other spheres? a. geosphere. b. hydrosphere. c. atmosphere. d. biosphere.

The answer would be D. Biosphere.

The biosphere "is the sum of all ecosystems." It is composed of all the living (biotic) and non-living (abiotic) components of Earth. This is where all the interactions of the other spheres occur which maintain and support all life. It extends to the other spheres; geosphere, hydrosphere and atmosphere.

explanation:

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
