  O reino Protista engloba seres unicelulares eucariontes, autótrofos ou heterótrofos, coloniais ou não. Consideram-se protistas os autótrofos como algas unicelulares e os heterótrofos como protozoários. No entanto, ambos os grupos não representam categorias taxonômicas tais como filo, classe ou ordem, mas apenas uma forma de diferenciar os organismos quanto à capacidade ou não de sintetizar compostos orgânicos a partir de inorgânicos. Os hábitos alimentares também são variados. Quanto ao modo de nutrição, os protozoários são classificados como heterótrofos ou holozoicos. Assinale a alternativa correta.

  Escolha uma alternativa para a questão 4508d82b-dd

  A

  Alguns protozoários possuem envoltórios protetores permanentes; outros só apresentam envoltório em condições ambientais desfavoráveis. Os protozoários podem ser só móveis; a locomoção pode ser realizada por flagelos, cílios ou pseudópodes. A presença e o tipo de estrutura locomotora são os critérios adotados para classificá-los.

  B

  O filo Sarcodina agrupa os protozoários que se locomovem por meio de pseudópodes. Entre eles está a Amoeba proteus, ameba comum que habita água doce e limpa onde há vegetação verde. Esse organismo tem estrutura bastante complexa, como uma massa incolor e gelatinosa de até 0,6 mm de comprimento.

  C

  O filo Mastigophora é composto pelos flagelados, protozoários que apresentam um ou mais flagelos, estruturas utilizadas na locomoção, na captura de alimento e, em certos casos, como receptores sensitivos. Alguns representantes desse filo podem apresentar uma espécie de colarinho, formado por finos pseudópodes dispostos transversalmente entre si contornando a base do flagelo.

  D

  Também classificadas no reino Protista, as algas unicelulares e eucariontes são fotossintetizantes. Todas possuem clorofila a, armazenada em cloroplastos, além de outros pigmentos como as clorofilas b, c e d, os carotenoides, as xantofilas e as ficobilinas. A coloração exibida pela alga depende do tipo e da quantidade de pigmento presente e é um critério utilizado para classificar a alga em uma das seguintes divisões: Chrysophytam pyrrhophyta e Euglenophyta, O outro critério baseia-se no tipo de composto orgânico armazenado como produto da respiração.

  E

  Além do flagelo, a Euglena possui espécies de listas proteicas e flexíveis que, associadas à membrana plasmática, constituem uma estrutura chamada película. Graças à película, essas algas podem se locomover e alterar sua forma. Não há parede celular nesses indivíduos. As euglenófitas são fotossintetizantes, apresentam fototropismo positivo, desde que a luz fornecida não seja muito intensa. Em condições favoráveis de luz, água e temperatura, desenvolvem-se rapidamente, formando uma espécie de nuvem verde sobre a água.

  Para que o equilíbrio dinâmico dos seres vivos seja mantido, todas as funções vitais devem ser desempenhadas da forma mais harmoniosa possível. Para isso, existem mecanismos que captam informações e que controlam e integram essas funções. O sistema nervoso é um dos responsáveis por esses mecanismos em um número bastante grande de espécies de seres vivos. O papel do sistema nervoso é receber, processar e enviar informações do e para o organismo, de forma que este se mantenha em equilíbrio. Seu principal componente é o tecido nervoso cujas células são excitáveis, ou seja, sofrem alterações de permeabilidade em sua membrana sempre que um estímulo é fornecido.

  
  

  

  
  

  Assim, é correto afirmar que
  

  Escolha uma alternativa para a questão 45023236-dd

  A

  o estímulo determina uma resposta que pode ser local ou não. Para haver resposta, o estímulo precisa ser captado por um receptor. Todo órgão ou célula que tem sensibilidade especial para determinada categoria de estímulo é um receptor. Assim, os termorreceptores não são sensíveis ao calor, enquanto os fotorreceptores se excitam na presença da luz.

  B

  o sistema nervoso não está presente em todos os seres vivos. Em animais como água-viva e anêmona, encontra-se o sistema nervoso organizado da forma mais simples. Trata-se de uma rede nervosa difusa, isto é, não espalhada por todo o corpo.

  C

  a camada mais externa do encéfalo é composta por grande quantidade de corpos celulares de neurônios. Essa camada é conhecida como substância cinzenta e constitui uma região denominada córtex. No ser humano, a substância cinzenta, apesar de ter apenas 5 mm de espessura, abriga cerca de 14 bilhões de neurônios e suas respectivas sinapses.

  D

  o encéfalo e a medula são revestidos por três membranas, as meninges. A mais externa e espessa é a pia-máter, que se encontra aderida aos ossos do crânio e da coluna vertebral. Abaixo dela situa-se a aracnoide-máter, uma membrana extremamente fina e frouxa. Intimamente aderida ao tecido nervoso, principalmente ao que compõe a medula espinal, está a delicada duramáter.

  E

  os nervos cranianos partem aos pares de diversas regiões do encéfalo, estendendo-se até os órgãos sensitivos, os músculos e demais estruturas. Os vertebrados possuem dez pares de nervos cranianos, exceção feita aos mamíferos, que apresentam doze pares. Existem 33 pares de nervos espinais. Eles partem da medula através do espaço existente entre uma vértebra e outra.

  A

  O darwinismo estabeleceu o conceito de seleção natural e de herança dos caracteres adquiridos.

  B

  Para Darwin, o ambiente induz os seres a se modificarem para se adaptarem a ele. Para Lamarck, o meio age selecionando as mudanças já existentes.

  C

  O lamarckismo consistia de duas leis: lei do uso e desuso e lei da seleção natural.

  D

  Para Lamarck, o ambiente induz os seres a se modificarem para se adaptarem a ele. Para Darwin, o meio age selecionando as mudanças já existentes.

  E

  Darwin, ao explicar o comprimento do pescoço da girafa, dizia que este teria se alongado devido à necessidade de alcançar alimentos nas partes mais altas das árvores. Já Lamarck entendia que, no passado, os ancestrais das girafas atuais possuíam pescoços de tamanho variável, e a competição pelo alimento disponível favoreceu as girafas de pescoço longo.

  Engenharia Genética ou Tecnologia do DNA Recombinante é um conjunto de técnicas que permite aos cientistas identificar, isolar, multiplicar e expressar genes de quaisquer organismos. Observe o esquema a seguir e assinale a alternativa correta.

  
  

  
  

  Escolha uma alternativa para a questão 44fb8a3d-dd

  A

  Por meio das técnicas de DNA Recombinante, é possível a clonagem de genes de interesse para expressão e produção de insulina, hormônio de crescimento ou plantas transgênicas, por exemplo.

  B

  Clonagem refere-se aos processos usados para criar cópias de fragmentos de DNA (Clonagem Molecular), células (Clonagem Celular), ou organismos. Esse fenômeno ocorre somente em ambiente laboratorial.

  C

  As enzimas de restrição ou endonuclease de restrição são proteínas que reconhecem e clivam o DNA em pontos específicos, geralmente em sequências de 4, 6 e 8 bases – palíndromas. Uma endonuclease de restrição é como uma ferramenta que permite cortar moléculas de DNA de forma desordenada e reprodutível.

  D

  A Tecnologia do DNA Recombinante, também conhecida como clonagem gênica ou clonagem molecular, compreende processos de transferência de células de um mesmo organismo.

  E

  A geração de moléculas recombinantes pela clonagem molecular não deve ser diferenciada daquelas obtidas por outros processos como, por exemplo, o de crossing-over que ocorre entre cromossomos homólogos de eucariotos.

  A herança dos grupos sanguíneosUFGD · 2017MédioEntre para guardar nos favoritos

  Leia o texto a seguir.

  
  

  Pode-se classificar em cinco os métodos de verificação dos caracteres hereditários existentes nas células sanguíneas, para fins de exclusão de paternidade, quais sejam: determinação de marcadores eritrocitários; séricos e enzimáticos; cromossômicos; leucocitários e de DNA. Tais exames constituem grande contribuição às ações de investigação de paternidade. O famoso sistema ABO foi descoberto no ano de 1900 por Karl Landsteiner, apresentando quatro tipos sanguíneos A, B, O e AB, sendo o mais comum o tipo O. A partir de então, esse sistema passou a integrar o caderno processual das ações investigatórias, sendo comumente conhecido por “exame de sangue”. E na grande maioria das vezes seus resultados se prestam para excluir a paternidade.

  No que se refere à herança dessas características, este sistema é determinado por alelos múltiplos, ou seja, existem mais de dois lócus diferentes para o mesmo gene, embora no mesmo genótipo só se apresentem dois deles ao mesmo tempo e como sempre um herdado do pai e outro da mãe. Assim, existem 3 alelos: I a, I b, i, capazes de ocuparem dois a dois um certo lócus gênico.

  Machado, C. P. A prova nas ações de investigação de paternidade. 2006. Disponível em:<http://www3.pucrs.br/pucrs/files/ uni/poa/direito /graduacao/tcc/tcc2/trabalhos2006_2/cristina.pdf> Acesso em: 21 set. 2017.

  
  

  Considerando essas informações, assinale a alternativa correta.
  

  Escolha uma alternativa para a questão 44f7f3e7-dd

  A

  Os genes “I a” e “I b” são recessivos sobre i, mas dominantes entre si.

  B

  É impossível uma criança de tipagem sanguínea do grupo O ter pai com tipagem sanguínea do tipo A e mãe com tipagem B.

  C

  Se a criança é O, seu genótipo é ii, recebendo um gene i de seu pai e outro de sua mãe; seu genótipo é ii, já que o grupo O é determinado por genes dominantes.

  D

  A afirmação “Filhos de pais de sangue O nunca podem ter sangue A” é verdadeira.

  E

  Um casal formado por um indivíduo com tipagem sanguínea do grupo A e o outro com tipagem sanguínea do grupo B pode gerar descendentes de todos os tipos sanguíneos.

  Mobile milestones: how your phone

  became an essential part of your life

  
  

  
  

  

  
  

  
  

  
  

      Has any device changed our lives as much, and as quickly, as the mobile phone? There are people today for whom the world of address books, street atlases and phone boxes seems very far away, lost in the mists of time. Following, there are just some of the big milestones from the past 30 years that have made almost everything we do easier, more public and very, very fast.

  • The first phones arrive – and become status symbols Few people got the chance to use the very early mobile phones. The first call was made in New York in 1973, but handsets with a network to use were not available until 1983 in the US, and 1985 in the UK. That first British mobile phone was essentially a heavy briefcase with a receiver attached by a wire. It cost £2,000 (£5,000 in today’s prices), and gave you half an hour’s chat on an overnight charge. Making a call was not something you could do subtly, but that wasn’t the point; the first handsets were there to be seen. They sent a message that you were bold and confident with new technology, that you were busy and important enough to need a mobile phone, and were rich enough to buy one.

  • Text messages spawn a whole new language

      The first mobiles worked with analogue signals and could only make phone calls, but the digital ones that followed in the early 1990s could send SMS messages as well. After the first message was sent on 3 December 1992, texting took off like a rocket, even though it was still a pretty cumbersome procedure. Handsets with predictive text would make things easier, but in the 1990s you could save a lot of time by removing all excess letters from a message, often the vowels, and so txtspk ws brn. Today the average mobile phone sends more than 100 texts per month.

  • Phones turn us all into photographers...

      There seemed to be no good reason for the first camera phones, which began to appear in 2002, with resolutions of about 0.3 megapixels. They took grainy, blurry pictures on postage stamp-sized screens, and even these filled the phone’s memory in no time. Gradually, though, as the quality improved, the uses followed. As well as the usual photos of friends and family, they were handy for “saving” pieces of paper, and in pubs you could take a picture of the specials board and take it back to your table. Modern camera phones have changed beyond recognition in the past 20 years. The new mobile phones boast the highest resolution dual camera on a smartphone: a 16-megapixel camera and a 20-megapixel camera side-by-side. The dual camera allows users to focus on their subjects, while blurring out the background, producing professional-looking portraits.

  • …and we turn ourselves into celebrities

      Twenty years ago people would have thought you a little strange if you took flattering photos of yourself and your lifestyle and then distributed them to your friends – let alone to members of the public. If you used printed photographs rather than a smartphone app, they would still think so today. Yet sharing our lives on social media is now the norm, not the exception – and it was the camera phone that made it all possible. Now, some phones come with an enormous 64GB of memory, so you can capture, share and store an almost countless number of videos and pictures – well, certainly enough to keep up with the Kardashians.

It cost £2,000 (£5,000 in today’s prices), and gave you half an hour’s chat on an overnight charge. Making a call was not something you could do subtly, but that wasn’t the point; the first handsets were there to be seen. They sent a message that you were bold and confident with new technology, that you were busy and important enough to need a mobile phone, and were rich enough to buy one.

  • Text messages spawn a whole new language

      The first mobiles worked with analogue signals and could only make phone calls, but the digital ones that followed in the early 1990s could send SMS messages as well. After the first message was sent on 3 December 1992, texting took off like a rocket, even though it was still a pretty cumbersome procedure. Handsets with predictive text would make things easier, but in the 1990s you could save a lot of time by removing all excess letters from a message, often the vowels, and so txtspk ws brn. Today the average mobile phone sends more than 100 texts per month.

  • Phones turn us all into photographers...

      There seemed to be no good reason for the first camera phones, which began to appear in 2002, with resolutions of about 0.3 megapixels. They took grainy, blurry pictures on postage stamp-sized screens, and even these filled the phone’s memory in no time. Gradually, though, as the quality improved, the uses followed. As well as the usual photos of friends and family, they were handy for “saving” pieces of paper, and in pubs you could take a picture of the specials board and take it back to your table. Modern camera phones have changed beyond recognition in the past 20 years. The new mobile phones boast the highest resolution dual camera on a smartphone: a 16-megapixel camera and a 20-megapixel camera side-by-side. The dual camera allows users to focus on their subjects, while blurring out the background, producing professional-looking portraits.

  • …and we turn ourselves into celebrities

      Twenty years ago people would have thought you a little strange if you took flattering photos of yourself and your lifestyle and then distributed them to your friends – let alone to members of the public. If you used printed photographs rather than a smartphone app, they would still think so today. Yet sharing our lives on social media is now the norm, not the exception – and it was the camera phone that made it all possible. Now, some phones come with an enormous 64GB of memory, so you can capture, share and store an almost countless number of videos and pictures – well, certainly enough to keep up with the Kardashians.
