Vamos con los reactivos del 9 al 16, correspondientes a la materia de inglés del simulador para el ingreso al IPN.
Esta parte puede ser un regalo en el examen… pero solo si le estudiaste tantito. Si hiciste tu chamba y te aplicaste aunque sea con lo básico, esta sección va a ser puro “easy points, baby“.
Llegamos a la parte donde, en teoría, todos deberían sumar puntos fáciles…
Pero spoiler alert: si no traes bien claros los básicos como el verb to be, los tiempos verbales o los pronombres, esta sección puede darte más lata de lo que crees.
Así que no te confíes. Dale bien, piensa en inglés (aunque sea por 8 preguntas) y que no se diga que te falló el “I am, you are, he is…”
No dejes que te suelten un “You’re gonna be carried by the clown” cuando salgan los resultados.
Conoce el curso que cubre todos los temas del nuevo examen de ingreso al IPN con clases en vivo y exámenes simulacro.

Mercury Transport by Rivers
Rivers carry approximately 1,000 tons of mercury to the world’s coastlines each year, according to a study published in Nature Geoscience. This research suggests that rivers are the main pathway through which this neurotoxin reaches coastal oceans, where it poses the greatest threat to public health. Human mercury exposure is primarily linked to consumption of fish from coastal fisheries, where the heavy metal accumulates in marine life. However, much of this pollution originates from inland sources such as wildfires, mines, and coal-burning power plants. Yale University biogeochemists developed a new model indicating that rivers could transport approximately three times more mercury to coasts than the atmosphere, and that half of this total can be traced to the planet’s 10 largest rivers. This finding contradicts the traditional belief that mercury travels primarily through the atmosphere.

The Impact of Climate Change on Coral Reefs
Coral reefs are facing an unprecedented crisis due to global climate change. According to recent research published in Science, more than 50% of the world’s coral reefs have disappeared in the last 30 years, and it is projected that up to 90% could be lost by 2050 if current trends continue. The main factor threatening corals is increasing ocean temperature, which causes coral bleaching—a phenomenon in which corals expel the symbiotic algae living in their tissues, losing their main food source. Additionally, ocean acidification, caused by the absorption of atmospheric carbon dioxide, makes it difficult for corals to form their calcium carbonate skeletons. Scientists are developing strategies to save reefs, such as selective breeding of heat-resistant coral species and the creation of protected marine sanctuaries. A recent study from the University of Miami shows that some reefs have demonstrated resilience after bleaching events, providing hope for future conservation.
