Answer:
Facilitated diffusion.
The cell with mutated membrane proteins can not transport calcium ions. Simple diffusion does not use membrane proteins to transport the substances.
Explanation:
Simple diffusion differs from facilitated diffusion in not using any membrane protein to transport the substances. Both simple and facilitated diffusion move the substances down their concentration gradient in a passive process.
However, facilitated diffusion makes use of integral membrane proteins to allow the charged or polar molecules to cross the membrane. These integral membrane proteins serve as channel or carrier and allow the polar and charged substances to cross the non-polar core of the membrane.
Calcium ions are charged particles and can not cross the non-polar core of the membrane. The cells with mutated membrane-bound proteins are not able to transport these ions. This suggests that calcium ions were moved across the membrane by facilitated diffusion through the wild type membrane-bound protein.
Answer:
Why a bilayer?
What's on the inside of the cell and on the outside? Mostly water. As you can see here, the water-based interior of the cell has lots of components. These need to be kept inside the cell. And it is the nature of the phospholipid bilayer to keep the inside of the cell separate from the outside.

Answer:
The biosphere is influenced by other spheres and also influences other spheres.
The biosphere comes into contact with several other spheres such as the hydrosphere, the lithosphere, and the atmosphere.
Contact with the atmosphere is a two way street since the biosphere can alter the composition of the atmosphere. However, many members of the biosphere like mammals and birds depend on the mix of gases in the atmosphere to survive, and weather is an important agent of change.
The lithosphere is another sphere that can impact the biosphere through geologic activity both underground and on the surface. The impact of the biosphere on the lithosphere can be observed through the altering and transformation of terrains and through biochemical weathering of rocks.
