Explanation:
Quartzite
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.
Texture - granular.  
Grain size - medium grained; can see interlocking quartz crystals with the naked eye.  
Hardness - hard.  
Colour - variable - pure quartzite is white but quartzite exists in a wide variety of colours.  
Mineralogy - quartz.  
Other features - generally gritty to touch.  
Uses - pure quartzite is a source of silica for metallurgical purposes, and for the manufacture of brick; as aggregate in the construction and roading industries; as armour rock for sea walls; dimension stone for building facings, paving etc.  
New Zealand occurrences - northwest Nelson (Aorere).
 
        
                    
             
        
        
        
Answer:
The argument can be contradicted by assuming that both animals and fungi exhibit heterotrophy and have intracellular spindles.
Explanation:
If an argument is required to demonstrate that fungi have common characteristics, it can be taken into account that:
- <em>They are</em><em> heterotrophic organisms</em><em>, since they are not able to synthesize their own nutrients, such as plants.
</em>
 - <em>Both </em><em>have intracellular spindles</em><em> in their structure, useful when performing the corresponding cell division.
</em>
 - <em>Additionally, both animals and fungi can </em><em>store glycogen</em><em> as a reserve of energetic substrate.</em>
 
It is currently thought that fungi and animals have a convergent or parallel evolution.

 It illustrates the cycling of matter, just like in a natural ecosystem. 
Option D. 
<h3><u>Explanation:</u></h3>
The natural stable ecosystem is defined as the ecosystem which has the members doing their part of job and each and every member contribute to the stability of the ecosystem by completing food chains.
Here in this bottle ecosystem the boy put the stones, rocks, water which gives proper nutrition to the growing plants and animals which are also introduced by the boy. The plants produce oxygen and consume carbon dioxide whereas the animals consume oxygen and produce carbon dioxide. Thus the cycle is maintained and stability is achieved.
