lesser 
Explanation:
Reykjavik the capital city of Iceland heats its buildings using geothermal energy sources at a cost that is lesser of what it would be if oil were  used. 
In all ramification, the use of geothermal energy sources is far more preferable and better than using fossil fuels like oil. 
- Geothermal energy is energy from within the earth 
- It is natural and renewable source of energy. 
- The cost of product is very low
- It has little to no impact on the environment as well. 
- They are usually found where magma pockets are close to the surface

Carbohydrate residues attached to the membrane lipids are always positioned on the extracellular side of the membrane
Carbohydrates are significant parts of the cell membrane, present just on the external surface of the plasma layer, and are appended to proteins, framing glycoproteins, or lipids, and framing glycolipids. These carbohydrate chains might comprise 2-60 monosaccharide units and can be either straight or branched.
The carbohydrates of the membrane are engaged with cell bond and acknowledgment and go about as a physical barrier. Enormous, uncharged particles, for example, glucose can't diffuse through the membrane.
These carbohydrates structure particular cell markers, that permit cells to perceive one another. These markers are vital in the resistant framework, permitting safe cells to separate between body cells, which they shouldn't assault, and unfamiliar cells or tissues, which they ought to.
