Answer:
We live in an era of unprecedented road and highway expansion — an era in which many of the world’s last tropical wildernesses, from the Amazon to Borneo to the Congo Basin, have been penetrated by roads. This surge in road building is being driven not only by national plans for infrastructure expansion, but by industrial timber, oil, gas, and mineral projects in the tropics.
Few areas are unaffected. Brazil is currently building 7,500 kilometers of new paved highways that crisscross the Amazon basin. Three major new highways are cutting across the towering Andes mountains, providing a direct link for timber and agricultural exports from the Amazon to resource-hungry Pacific Rim nations, such as China. And in the Congo basin, a recent satellite study found a burgeoning network of more than 50,000 kilometers of new logging roads. These are but a small sample of the vast number of new tropical roads, which inevitably open up previously intact tropical forests to a host of extractive and economic activities.

Answer:
Esto es cierto porque una célula se define como la unidad básica, estructural y funcional de todas las formas de vida. La célula podría ser simple o compleja y contiene la información más importante sobre el individuo conocido como su ácido nucleico. El DNA controla la composición genética y física del individuo, coordina su comportamiento y garantiza que se adapte a lo largo de su vida. Esto hace que la célula sea crucial para la vida de un individuo. Los atributos físicos en el individuo, como la altura y el color de la piel, son controlados por la célula, mientras que también controlan los atributos genéticos, como el genotipo y el grupo sanguíneo.
