What about cellouse makes it ideal for structural support

Answers

Answer:

Due to the strong intermolecular force of attraction in cellulose it provides high strength and support.

Explanation:

Cellulose is a significant polysaccharide since it is the most copious natural compound on Earth. Cellulose is a significant segment of intense cell dividers that encompass plant cells, and it's what makes plant stems, leaves, and branches so solid. It absolutely takes a ton of effort to cause damage to the structure of cellulose.  

Cellulose particles are arranged parallel to one another and are combined with hydrogen bonds. This structures long, link like structures, which join with other cellulose atoms and is the thing that produces such a solid help structure.

The noble gases are stable because they have how many electrons in their outer energy level?2
4
6
or 8

Answers

Noble gases are the least reactive of all known elements. That's because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons. Noble gases are gaseous elements; Including , neon , argon, krypton xenon and radon. These gases belong to the group 0 (18) of the periodic table. I hope this helps

What is the most likely effect a decrease of plant life in the biosphere would have on the atmosphere?a.
A decrease in plant life would have no effect on the atmosphere.
b.
A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease.
c.
A decrease in plant life would cause carbon dioxide levels to decrease and oxygen levels to increase.
d.
A decrease in plant life would cause an increase in all gases in the atmosphere.

Answers

A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease. Therefore option B is correct.

Plants play a crucial role in the biosphere by performing photosynthesis, a process that absorbs carbon dioxide (CO2) from the atmosphere and releases oxygen (O2) as a byproduct.

With a decrease in plant life, the rate of photosynthesis would decrease, resulting in reduced CO2 absorption and lower oxygen production.

As a consequence, carbon dioxide levels would increase in the atmosphere, leading to potential implications for global warming and climate change.

Additionally, the decrease in oxygen production could have adverse effects on the air quality and the oxygen supply necessary for supporting aerobic life forms.

Thus, the reduction of plant life could disrupt the delicate balance of atmospheric gases, influencing the Earth's climate and living organisms.

Therefore option B A decrease in plant life would cause carbon dioxide levels to increase and oxygen levels to decrease. is correct.
