natima [27]

The correct answer is option A, that is, a landfill in the region of nonporous bedrock.  

A permanent waste disposal facility where the wastes are put into the ground and covered with a layer of plastic, soil, or both is known a landfill. A secure chemical landfill refers to a landfill developed in the region of nonporous bedrock.

A secure chemical landfill is a prudently engineered depression in the ground or constructed on the top of the ground, signifying a football stadium into which wastes are dumped. The objective is to inhibit any water-related or hydraulic association between the surrounding environment and the wastes, mainly groundwater.

What can you conclude about the advantage of the cell membrane being made up of phospholipids?
sergiy2304 [10]
The phospholipid bilayer is a universal component of all cell membranes. Each phospholipid molecule has a hydrophobic(water repelling) and a hydrophilic( attracted to water) end. This allows the phospholipids to arrange themselves in a way that makes a cell membrane not able to dissolve in water. The bilayer is also semi-permeable which allows only certain molecules to enter the cell.
