Answer:
In models describing the structure of the plant cell wall, the polysaccharide cellulose,which only contains glucose,forms cable-like structures which are associated with interspersed hemicellulose polysaccharides which consist of glucose chains with xylose side groups. The pectin polysaccharides, containing ironic acids, have a more kinked ribbon-like structure and serve to link the cellulose polysaccharides together by providing a gel-like matrix,completing the cell wall structure.

Answer:
Distance also affects the apparent brightness of an object. A distant, but very energetic star can appear dimmer to us than a lower-energy, but closer one. ... Each of their effective temperatures results in a different brightness for the object. The quasar, however, is very far away, and so appears dim.

C- 14
Sc- 46
Na- 24
Mass number= proton+neutrons
Answer:
D. ammonia, because the other three are the only three strong bases in the world (we do not need to memorize base dissociation constant for the test, we just need to know the three strong bases)

All the other chices give evidence that supports that hypothesisthat the Moon was made of material that was flung off Earth during a time when it was rapidly spinning.
Explanation:
There is an enormous amount of similarities between the minerals in the moon rocks and the rocks on earth, except that for some minerals, like potassium, their quantities are higher on the earth than on the moon.
However, there is still supports for the evidence (by the other choices) that the moon was made from a piece of earth ejected from asteroid impact in primordial earth.Explanation:It’s believed that more than 3.5 billion years during the formation of earth and before it had cooled there were frequent asteroid impacts and one enormous collision ejected a large piece of molten earth into space but within earth’s gravity influence. This piece formed the moon. Evidence of asteroid impacts are frozen in time on the moon surface thanks to the fact that the moon has no atmosphere or tectonic plates movements that wipe off this ‘evidence’.
