Why are biofuels not necessarily the answer to energy problems?
tiny-mole [99]

1. Vantagens do uso dos biocombustíveis

- Possibilita o fechamento do ciclo do carbono (CO 2 ), contribuindo para uma estabilização da concentração do gás na atmosfera;

- No caso específico do Brasil, há grande área para o cultivo de plantas que podem ser utilizadas para a produção de biocombustíveis ; 

- Geração de emprego e renda no campo (assim evita o inchaço das cidades);

- Menor investimento financeiro em pesquisas (como pesquisas de prospecção de petróleo são muito despendentes);

- O substituto de biodiesel bem o óleo diesel sem necessidade de ajustes sem motor;  

- Redução do lixo no planeta (pode ser usado para produção de biocombustível ); 

- Manuseio e armazenamento de seguros e combustíveis fósseis.

 

2. Desvantagens do uso dos biocombustíveis

- Consome grande quantidade de energia para uma produção;

- Aumento de consumo de água (para irrigação das culturas);

- Redução da biodiversidade;

- Como culturas para produção de biocombustíveis consomem muitos fertilizantes nitrogenados, com liberação de óxidos de nitrogênio, que também são gases estufa;  

- Devastação de áreas florestais (grandes consumidoras de CO 2 ) para plantio das culturas envolvidas na produção dos biocombustíveis ; 

- Possibilidade de redução de produção de alimentos em detrimento do aumento da produção de biocombustíveis , o que pode contribuir para aumentar da fome no mundo eo encarecimento dos alimentos; 

- Contaminação de lençóis freáticos por nitritos e nitratos, participação de fertilizantes. A ingestão dos produtos causadores respiratórios, devido à produção de meta-hemoglobina (hemoglobina oxidada);

- A queima da cana libera grandes quantidades de gases nitrogenados, que retornam ao ambiente na forma de “chuva seca” de fertilizantes, segundo pesquisa do químico ambiental Arnaldo Cardoso e publicada na revista “Unesp Ciência, edição de fevereiro de 2010.  Nos ambientes aquáticos, o efeito é muito rápido: proliferação de algas, com liberação de toxinas e consumo de quase todo oxigênio da água, o que provoca a morte de um grande número de espécies.

Which two layers are part of the thermosphere? *
Alina [70]

Answer:

"Ionosphere and Exosphere" is the right response.

Explanation:

  • The ionosphere seems to be the interface through which the Northern side lights originally come, or perhaps the Aurora Borealis. This same radioactivity including its sun throughout the ionosphere ionized particles the particulates emitting the logo lighting system of Aurora.
  • The exosphere, having started from five hundred kilometers, would be the outermost part of that same thermosphere. This same exosphere appears to contain slightly heavier gasses including such helium.

of the three 'bypass' reactions that allow gluconeogenesis to produce glucose from pyruvate, two of these reactions are also poi
sergejj [24]

There are three bypass reactions in gluconeogenesis, out of them the one reaction which does not show reciprocal regulation is Pyruvate carboxylase and PEP carboxykinase bypass pyruvate kinase reaction.

The three bypass reactions where the energy transfer of ATP→ADP takes place are:

  • Glucose-6- phosphate bypasses the hexokinase step which is a reciprocal step
  • Fructose 1,6 bisphosphate bypasses the phosphofructokinase step, this step is also a reciprocal regulating step.
  • Pyruvate carboxylase and PEP carboxykinase bypass pyruvate kinase step is not a reciprocally regulated step, this reaction is the last step of gluconeogenesis leading to the formation of 2 molecules of pyruvate.
