Why are large boulders present in steep mountain streams?

Biology
1 answer:
Masja [62]3 years ago

Freeze thaw occurs on the mountain creating large chunks of rock which progress down stream. However a more logical answer would be calving,abrasion and plucking that are processes performed by a glacier removing peices of rock from the mountains. As these melt they form streams, large rocks and boulders would be left behind.

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.
