Answer:

i) Glucose

ii) β(1-4) glycosidic bonds.

iii) Oxygen

Explanation:

Cellulose is an important structural carbohydrate found in plants. It forms a major component of the plant cell wall.

Cellulose is a polysaccharide formed by monomers of glucose.  These glucose monomers are joined together by covalent bonds called β(1-4) glycosidic bonds, which means that the 1st carbon of one glucose is bound to the 4th carbon of the next glucose. To make this arrangement,  every other glucose molecule in cellulose is inverted, which you can see in the diagram.

Glucose monomers contain carbon, hydrogen, and oxygen only. If you look at the pattern of the molecule (remembering every second glucose is inverted), you can see that Z must be O.

The functional group denoted by Z is oxygen. The OH groups on the glucose from one cellulose chain form hydrogen bonds with oxygen atoms on the same or on another chain, holding the chains firmly together and forming very strong molecules - giving cellulose its strength.

Plants use nitrogen in fertilizers for growth. However, much of the nitrogen goes unused. What is one direct outcome of this exc
Olin [163]
There are many environmental negative direct outcomes of unused excess nitrogen from nitrogenous fertilizers. One of these is eutrophication. Eutrophication is the excessive richness of nutrients in a water body as a result of fertilizer run offs from the land, which causes a dense growth of plants in the water. Other negative outcomes are: green house effects, acid rain and contamination of underground water which has negative effects on human health.
