    O diabetes se caracteriza como uma doença relacionada aos distúrbios na glicemia. Nos diabéticos, o corpo perde a capacidade de controlar as concentrações sanguíneas de glicose, podendo aumentar o risco de outras complicações como câncer, infarto e acidente vascular cerebral. O controle da variação da concentração de glicose sanguínea é realizado por dois hormônios produzidos pelo pâncreas, insulina e glucagon, os responsáveis pela manutenção da glicemia sadia. Os gráficos abaixo representam a variação da concentração no sangue de glicose e desses dois hormônios durante um período de 0 a 5 horas após uma refeição.


    Nesse contexto, analise as afirmativas abaixo:

    I - A liberação de insulina pelo pâncreas ocorre quando as concentrações de glicose sanguínea são baixas.
    II - O pico da concentração da liberação de glucagon coincide com a máxima concentração de glicose no sangue.
    III - À medida que a concentração de insulina começa a declinar 1 hora após a refeição, é possível perceber a queda na concentração de glicose sanguínea.
    IV - A variação na concentração sanguínea de glicose regula da mesma maneira as variações dos dois hormônios.

    Está correto SOMENTE o que se afirma em:

    4º MOTIVO DA ROSA – Cecília Meireles



    Não te aflijas com a pétala que voa:

    também é ser, deixar de ser assim.


    Rosas verás, só de cinza franzida,

    mortas, intactas pelo teu jardim.


    Eu deixo aroma até nos meus espinhos,

    ao longe, o vento vai falando em mim.


    E por perder-me é que me vão lembrando,

    por desfolhar-me é que não tenho fim.

    Are video games the next big college sport?

    New kinds of competitors are joining student athletes at colleges and universities around the country. But not everyone agrees that these video game players are taking part in a sport. Sports are an established part of college life and a source of income for some schools. The football stadium at the University of Michigan in Ann Arbor, for example, holds over 107,000 people. It is one of the largest sports stadiums in the world!

    Like most traditional college sports, video game competitions involve two or more teams of students officially representing their schools. Team members wear clothing with their names and school colors. They even have coaches giving them advice on how best to win.

    However, there is no running or jumping or hitting other players. In fact, these new events are different from any traditional athletic activity. They are called esports, and they take place not in the real world, but in computers or other video game systems.

    Professional video game competitions have been popular around the world for years. Teams and individuals compete for prize money and awards in strategic military combat games like Starcraft and one-on-one fighting games like Street Fighter.

    What Parents Can Do to Nurture Good Writers

    Steve Graham, a professor at Arizona State University’s Teachers College, has been researching how young people learn to write for more than 30 years. He is a co-author of numerous books on writing instruction, including “Powerful Writing Strategies for All Students.”
    How does reading at home help children become better writers?
    is really critical, but it’s not enough. We don’t have much evidence that if you just read more, you’ll be a better writer. But analyzing text does make a difference. So when we read to kids, we can also have conversations with them about the author’s craft. How did this author make this place seem real in terms of description? What words did they use? How did they present this idea or this argument?
    Should a parent correct a child’s writing, or just be encouraging?
    Sometimes when kids come to you to share what they’re writing, they’re not coming for feedback. They are coming for affirmation. It’s really important we emphasize first and foremost what we really like about it. And if you’re going to give feedback, just pick one or two things. English teachers — and parents are guilty of this, too — sometimes overwhelm kids with more feedback than they can absorb all at once. The other thing that’s really important, particularly for parents, is to remember that they don’t own this piece. It’s their child’s.
    What should parents look for to assess the writing instruction at their child’s school?
    After about third grade, very little time is devoted to explicit writing instruction. It’s like we’ve imagined that kids have acquired what they need to know to be good writers by then! In middle and high school, the most common activities are fill-in-the-blanks on worksheets, writing single sentences, making lists or writing a paragraph summary. When you start talking about persuasive essays or an informative paper, those things occur infrequently in English class and even less so in social studies and science. So the first questions are: “Is my kid writing at school, and was he given writing assignments to work on at home? Do those require writing more extended thoughts for the purposes of analysis and interpretation?” That’s what they need to be able to do for college.

    How does Hurricane Harvey compare with Katrina? Here’s what we know

    Although it is still unfolding, Harvey, now a tropical storm, evokes comparisons to Hurricane Katrina in 2005. Here’s a quick rundown of what we know about similarities and differences between the two.

        • The Cities
    Katrina: Before the storm, New Orleans was a small city of about 455,000 people that lay in large part below sea level, ostensibly protected by a system of levee walls. Its population never fully recovered from the evacuation and destruction and remains below 400,000.
    Harvey: Houston is a sprawling, car-dependent, low-lying but not below sea level city. It has a population of more than two million people, with a system of bayous and waterways to manage flooding.

       • The Storms
    Katrina: It made landfall near the Louisiana/Mississippi border on Aug. 29, 2005, as a Category 3 storm and measured 350 miles across. However, the relatively low classification, was deceptive because Katrina produced the highest storm surge ever recorded in the U.S.
    Harvey: It made landfall in Rockport, Tex., on Friday as a Category 4 storm, measuring 200 miles across, but was quickly downgraded. As of Monday, it was expected to linger for days, causing the National Weather Service to warn, “This event is unprecedented and all impacts are unknown.”

         • Deaths and Damage
    Katrina: One of the deadliest hurricanes ever to strike the U.S., Katrina was responsible for 1,833 deaths, and some bodies were untouched for days. The storm inflicted more than $100 billion in damage, with most of it caused by wind, storm surge and the failure of the levees. Harvey: Local officials have reported at least 10 deaths in Texas since the storm began, but heavy rains and flooding are expected to continue at least through Friday. Most of the damage could be caused by flooding. As for the economy, the Gulf region’s capacity as an oil and gas does not appear to have been seriously compromised.

      • Assistance
    Katrina: The storm displaced over a million people and damaged or destroyed 275,000 homes. Almost a million households received individual assistance from the Federal Emergency Management Agency.
    Harvey: We don’t know yet how many people will be forced out of their homes. But the vast majority of homes in Harvey’s path are not insured against flooding, according to figures from the National Flood Insurance Program. It is estimated that 450,000 people were likely to seek federal aid.
