Answer:
Homoglycan:
Homoglycan are the chemicals that are made up of one type of monosaccharide monomers only. They are the homopolymer carbohydrates. For example: galactans made up of glucose unit linked through the glycosidic bonds.
Heteroglycan:
Heteroglycans are the chemical that are made up of different monosaccharide units. They are heteropolymer carbohydrates. For example: Hayluronic acid made of D-glucuronic acid and N-acetyl-D-glucosamine linked through glycosidic bonds.
The best answer is pneumatophores.
In the environment where mangroves grow, oxygen is very limited. This necessitates mangrove root system to take up oxygen from the atmosphere. For this purpose, mangrove species have specialized above ground roots called pneumatophores or breathing roots.
In some species, these roots are pencil sized and peg-like while in others they look like a knee. These roots have numerous pores through which oxygen enters into the underground tissues. In some plants, buttress roots function as breathing roots and also provide mechanical support.
Answer:
The main role of carbonic anhydrase in humans is to catalyze the conversion of carbon dioxide to carbonic acid and back again. However, it can also help with CO2 transport in the blood which in turn helps respiration. It can even function in the formation of hydrochloric acid by the stomach.
