Em pesquisa publicada recentemente, cientistas identificaram poluentes orgânicos persistentes (POPs), banidos há décadas, em sete espécies de aves marinhas na costa do Brasil (seis migratórias e uma nativa). O achado serve de alerta para os riscos de contaminação na alimentação humana.
A relação entre a contaminação das aves marinhas e o risco para os seres humanos pode ser explicada pelos fenômenos conhecidos como bioacumulação e biomagnificação.
Sobre eles, é correto afirmar que
Com o objetivo de identificar e superar concepções equivocadas sobre mudanças climáticas e compreender o papel das ações humanas nesse processo, o professor propôs a análise dos itens a seguir.
I. O desmatamento e as queimadas são ações antrópicas que contribuem para as mudanças climáticas pois, além de interferirem no ciclo do carbono, alteram também o processo de evapotranspiração.
II. O efeito estufa é um fenômeno natural fundamental para manter a temperatura do planeta propícia à vida, mas a ação humana intensifica esse processo ao aumentar a retenção de calor na atmosfera.
III. A preservação das florestas em estágio clímax, como a Amazônia, é fundamental para mitigar as mudanças climáticas, pois esses ecossistemas apresentam elevada produtividade primária líquida e, por isso, realizam continuamente o maior sequestro de carbono da atmosfera entre todos os ecossistemas terrestres.
Está correto o que se afirma em
Com relação à audição humana e aos impactos causados pela poluição sonora, assinale (V) para afirmativa verdadeira e (F) para falsa.
( ) A cóclea é o componente da orelha interna responsável pela audição. A chegada das ondas sonoras faz com que o líquido em seu interior se movimente, estimulando as células sensoriais ciliadas a converterem a energia sonora em impulsos elétricos.
( ) A poluição sonora pode causar estresse, hipertensão e problemas cardíacos, especialmente quando há exposição frequente ou prolongada a níveis elevados de ruído.
( ) O zumbido no ouvido após o uso de fones em volume alto é uma resposta protetora do organismo e indica uma adaptação fisiológica do tímpano e das células sensoriais, tornando-os tolerantes à exposição a elevados decibéis.

Com relação ao bioma Cerrado, analise os itens a seguir.
I. É composto principalmente por formação do tipo savana, mas também apresenta trechos de formações florestais, nos quais há predominância de espécies arbóreas, que formam um dossel contínuo.
II. É o segundo maior bioma brasileiro, mas possui baixa biodiversidade, pois o longo período anual de estiagem, o solo pobre em nutrientes e a ocorrência sistemática de incêndios naturais são fatores limitantes à sobrevivência.
III. Apresenta uma porção subterrânea da vegetação que, em geral, constitui maior biomassa que a parte aérea, formando uma espécie de “floresta invertida”. Muitas espécies possuem raízes profundas, que desempenham papel importante na manutenção dos rios que abastecem grande parte do país.

ELF and the Brazilian National Core Curriculum
The current Brazilian National Core Curriculum (BNCC) adopts English as a Lingua Franca (ELF) as a guiding concept for English Language Teaching (ELT) across the country’s basic education system. While the measure has sparked debate and controversy, ELF’s inclusion in the document is generally seen as an innovative step. However, its implementation has brought significant challenges, especially for teachers who often lack a clear understanding of the concept or how to incorporate ELF-aware practices into their classrooms. These challenges underscore the pivotal role of teacher education in effectively integrating ELF into ELT in local contexts.
