Read this text about Yuri Gagarin.

Yuri was born on March 9, 1934 in Klushino, a small village 100 miles west of Moscow. His father was a cabinetmaker, carpenter, bricklayer, and farmer, and his mother was a milkmaid. Together they worked on a kolkhoz or collective farm. By Soviet social standards, his heritage was impeccable. He was the third of four children. During the war, the Nazis threw his family out of their home and took away two of his sisters. Yuri helped his parents dig a dugout where they lived untill the war was over, then the family moved to Gziatsk. 

[…] 

Yuri was subjected to extremely rigorous training: physical, mental, and psychological. He underwent long periods in a sensory deprivation chamber, experiments with weightlessness, endurance in heat chambers, and test flights under stress with every reaction monitored. […] 

"During the days of preparation for the launch, when everyone had more than his share of concerns, apprehensions, and anxieties, he alone seemed to keep calm. More than that: he was full of good spirits and beamed like the sun." 

On April 12, 1961 the first earthling escaped the gravity well of planet earth. In the spaceship Vostok 1, Senior Lieutenant Yuri Alexeyevich Gagarin orbited earth one time at an altitude of 187 3/4 miles (302 kilometers) for 108 minutes at 18,000 miles an hour. He was the first man to see that the earth was indeed round, indeed mostly water, and indeed magnificent. 

Following his return to earth, Yuri's triumphant walk through Red Square in front of a crowd of hundreds of thousands made him more nervous and afraid than his historic flight. As he reached the podium, the awaiting Valya tearfully whispered in his ear, "Our dream has come true, Yuri." Embracing her he replied, "You're a smart girl! Thank you!" [...]

(UFPR) A narcolepsia é um distúrbio de sono que acomete a espécie humana e outros animais. Com o objetivo de investigar a causa da doença, pesquisadores da Universidade de Stanford (EUA) introduziram cães narcolépticos em sua colônia de animais saudáveis e realizaram cruzamentos, alguns deles representados no heredograma abaixo. Os animais 1, 2, 4 e 11 são os animais narcolépticos introduzidos na colônia. Após anos de pesquisa concluíram que nos cães a transmissão da narcolepsia é resultante da ação de um par de alelos.

A partir dessas informações, responda: Qual é a probabilidade de um filhote do casal formado pelos animais 13 e 16 nascer com narcolepsia?

(UNIPÊ) Um medicamento que contém 1,0 g de extrato vegetal dissolvido em 1,0.10⁵ g de água é uma solução aquosa de concentração muito pequena e que, do ponto de vista prático, é constituído de água pura. Entretanto, medicamentos desse tipo são comuns em homeopatia, terapia alternativa iniciada pelo médico alemão Christian Samuel Hahnemann, em 1796, que até essa época praticava o princípio da medicina alopática de que os opostos se curam. Entre a comunidade médica e científica internacional, a homeopatia é geralmente tida como pseudociência, mas, no Brasil, é considerada como especialidade médica desde 1980, reconhecida pelo Conselho Federal de Medicina, tendo sido incluída no Sistema Único de Saúde (SUS) desde 2006. Reino Unido, França e Alemanha também usam a homeopatia em seus sistemas de saúde pública.

Segundo pesquisas realizadas por Hahnemnn, os medicamentos seriam sempre muito diluídos em solventes apropriados, geralmente água ou uma mistura de água e álcool, e o médico homeopata tentaria eliminar os efeitos de uma doença com medicamentos que causassem os mesmos sintomas em uma pessoa sadia.

Considerando-se essas informações, é correto afirmar:
