Q3764228 Biologia
Durante a gastrulação, ocorre um acentuado crescimento e diferenciação das células, formando-se os folhetos embrionários, inicialmente dois: ectoderme e endoderme.
Na gastrulação por invaginação (ou embolia), os micrômeros sofrem divisões mitóticas mais rápidas do que os macrômeros, gerando forças que provocam a invaginação destes últimos, que acabam se posicionando internamente à camada de micrômeros. Com isso, a blastocele desaparece gradualmente e dá origem a uma nova cavidade interna, o (X), futuro tubo digestório, que se comunica com o exterior por meio do blastóporo. Nesse estágio, o embrião é chamado de glástrula, e já estão definidos os dois folhetos embrionários: ectoderme e endoderme.

Em uma floresta tropical, duas espécies de pássaros (A e B) que alimentam-se dos mesmos frutos produzidos por uma planta local, especialmente durante o período de escassez. Observa-se que, quando a população da espécie A aumenta, a disponibilidade de alimento para a espécie B diminui, afetando sua taxa de reprodução. Na mesma região, pesquisadores identificaram uma infestação de ácaros em mamíferos silvestres. Esses ácaros vivem na pele dos hospedeiros, alimentando-se de células epiteliais e secreções, o que causa irritações, mas raramente leva o animal à morte. Com base nas informações apresentadas, assinale a alternativa CORRETA.

Em um sistema heterogêneo, as porções homogêneas são denominadas fases. Quanto ao número de fases, os sistemas são classificados como: monofásicos possuem apenas uma única fase (logo, são homogêneos); e polifásicos que possuem mais de uma fase (portanto, sempre heterogêneos). Baseado nessas informações, a figura acima apresenta quantas fases e quantos componentes? Assinale a alternativa CORRETA.

“Tomato crisis” spreads panic in Nigeria


Making jollof rice, a beloved traditional dish in Nigeria, has suddenly become very expensive. Tomatoes, one of its main ingredients and a staple of Nigerian cuisine, are going for $2 each ____ local markets, with wholesale baskets costing as much as N42,000, or $212, Kaduna state agriculture commissioner Manzo Daniel told AFP.

The culprit is a moth called Tuta absoluta, which has destroyed crops in the northern Kaduna state, forcing the local government to declare a state of emergency. “It is a serious problem. The disease has affected production and consumption, prices are continuing to rise and there is no availability,” Shehu Sani, Senator for Kaduna Central, told CNN.

The area, which contributes strongly to Nigeria’s overall production, has already seen losses of millions of dollars, according to Sani. “Many depend ____ tomato farming for their livelihood and tomatoes are an indispensable part of the diet. People cannot do without them,” he said.

The tomato crisis comes on the heels of a recent fuel shortage and a general rise in commodity prices due to inflation and a lack of foreign currency. In local towns, the problem has been labeled “Tomato Ebola”. “People are panicking, because attaching that name to a staple food has worsened the situation,” said Sani. Even those who can afford to buy find it difficult to trust any tomato product, and some have started buying imported tinned tomatoes. “Nobody knows now which tomatoes are safe to eat and some people are avoiding them altogether.”

Nigerians have taken to Twitter to lament the situation, pointing out ____ playful disbelief that while they have to pay dearly for tomatoes, at an annual festival in Spain they are wasted for fun. The next ‘La Tomatina’ festival isn’t due until August, but ____ then Nigerians hope they’ll have gone back to tomato-normality.
