Not exactly. As you compare the polar desert in the Arctic to that in Antarctica, several differences come to light. Arctic. The topography of the Arctic polar desert is defined as tundra, glaciers, and snow.hen the weather warms up, and the warmest month of the year rolls around, the temperature remains in the range of a few degrees Celsius to approximately -1 degree Celsius. In terms of precipitation, the Antarctic polar desert receives less than 40 millimeters per year.
5 Main Groups of Polysaccharides: 1. Starch. 1  Chemically, consists of long chains of glucose (a monosaccharide, see above) molecules. 2  Formed by plants during photosynthesis. 3  Present in many plant-based food sources, such as root vegetables. 4  e.g. potatoes, cereals e.g. and pulses.
Simple Sugars. Ribose contains five carbon atoms in a ring, which makes it a simple sugar or monosaccharide. Disaccharides consist of two sugars bonded together; common table sugar, or sucrose, contains fructose and glucose, so it's a disaccharide.he sugar ribose also makes up part of the structure of RNA. One of the simplest sugars, ribose plays an integral part in biochemistry. Ribonucleic acid, or RNA, gets its structure from ribose chains.
