Carbon moves from the atmosphere to the biosphere and also from the atmosphere to the hydrosphere through a variety of processes.
<h3>Carbon cycle</h3>
Carbon in the form of carbon dioxide in the atmosphere is sequestrated by plants (biosphere) through a process known as photosynthesis.
When plants die, their organic matter decomposes into the soil (lithosphere) while some carbon is released back into the atmosphere via decomposition. Soil carbon also helps plants to grow.
Carbon in the atmosphere also gets sequestrated into water bodies (hydrosphere) by dissolution.

A)animal cells must be in osmotic equilibrium with their surrounding environments, because if they swell or shrink their membranes will rupture.
Answer:
A
Explanation:
Typically across all life, the plasma membrane of cells is made up of a bilipid layer of phospholipids. The phosphate ends of the molecules, which are hydrophilic hence ‘face’ the interior and exterior of the cells. The fatty acid chains, which are hydrophobic are embedded in between because they no charges hence do not interact well with charged molecules. The phosphate ends, on the other hand, are negatively charged hence can interact well with the polar water molecules. It is therefore usually a challenge for molecules with charges to diffuse across the membrane without the help of channel proteins that will help them cross the hydrophobic layer.
I’m going to say *True* if you agree I must be right!
Hope I helped! : )
