The right answer is cellulose
Cellulose is a carbohydrate consisting of a linear chain of D-glucose molecules (between 15 and 15,000). This biopolymer is the main constituent of the plant cell wall, including wood (which is also characterized by a high lignin content).
Pectin is also the structure of plant cells, but they are heteropolysaccharides.
Answer
Chemical elements and water are constantly recycled in the ecosystem through biogeochemical cycles. During the water cycle, water enters the atmosphere by evaporation and transpiration, and water returns to land by precipitation.

Olá!!! Bom vamos lá!
O nucleotídeo é constituído de um açúcar,um grupo fosfato e uma base nitrogenada. Nesse caso estamos falando de subunidade então podemos dizer que estamos falando do RNA ou DNA, logo, teremos a desoxirribose como açúcar.
Depois teremos um grupo fosfato e assim as bases nitrogenadas ( Guanina, Timina/Uracila, Citosina, Adenina) Sendo que C combina com G e A combina com T/U , vamos usar a base T quando for DNA, e quando for RNA vamos usar U. Por isso a resposta correta é a letra B!
Espero ter ajudado em algo!
Answer:
Due to inability to survive in aerobic condition.
Explanation:
The strain dies when exposed to a normal laboratory atmosphere instead of nitrogen gas atmosphere because the mutation causes change in the capability of the strain to survive in the aerobic conditions. This mutation inactivate several enzymes which is also responsible for their capabilities of surviving under both anaerobic and aerobic environment so that's why the strain dies when exposed to normal atmosphere..
