Answer:
They are all carbohydrates.
Explanation:
Homo polysaccharides include starch, glycogen, and cellulose (same type of sugar-all made of glucose).
1- Amylose and Amyloprotein are the components of starch. Amylose is a branched chain with alpha 1–4 and alpha 1–6 at the branch point, whereas Amylopectin is a linear chain with alpha 1–4 and alpha 1–6 at the branch point.
2- Glycogen is created by forming a branched chain from glucose at alpha 1–6. It has a lot of branches.
3- Cellulose is a linear chain of glucose molecules with beta bonds.
Starch and glycogen serve as short-term energy stores in plants and animals, cellulose found in plant cell wall only.

Answer:
Comparative anatomy. 
Explanation:
Comparative anatomy is a branch of science in which we study about similarities and differences present in different organisms. This type of study is very important for the classification of living organisms. Comparative anatomy tells us about the evolution of an organism. Scientists study DNA, embronic structure and the internal structure of species to see the evolution of different organisms.
