How many peaks does the landform in the topographic map contain?
Aloiza [94]

Answer:

3 peaks

Explanation:

Topographic map is used to show different landforms using different symbols. There are two important elements of landforms that include elevation and slope. It uses contour lines to portray different features of lands on the map such as slope and elevation.

<em>According to topographic maps, more close are the counter lines, more elevation are in the landforms. </em>

Peak is the pointed top of mountains. In this topographic maps peaks or elevation is shown in the form of irregular spherical shape. There are 4 elevations in the map but only 3 shows the peak according to counter line formation and the fourth elevation will not have peak on the top.

Hence, the given topographic map has only 3 peaks in the landform.

____________ is a polysaccharide that is found primarily in plant cells as a form of energy storage. it is ____________ and as a
zvonat [6]

Answer;

-Starch, moderately branched

-Starch is a polysaccharide that is found primarily in plant cells as a form of energy storage. it is moderately branched and as a result, it is not very soluble in water.

Explanation;

-Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Starch is among the three important polysaccharides that are composed of glucose, others being, glycogen, and cellulose, are composed of glucose.

-Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by α glycosidic bonds.

-Glycogen and starch are highly branched, which is an advantage in that the enzymes that build up and break down glycogen and starch act on the free ends of the polysaccharides. The branching thus ensures that plants and animals can quickly add to their energy supply when energy is plentiful, or break it down the storage molecules when energy is in short supply.
