Neste mês de julho, celebramos o aniversário de 200 anos de Gregor Johann Mendel (20 de julho de 1822 — 6 de janeiro 1884), um monge agostiniano que ficou conhecido como o “pai da genética”. Nascido em 1822 no Império Austro-Húngaro, em uma família de agricultores humildes que possuíam poucos recursos para investir em sua educação, Mendel decidiu entrar para o clero como meio de trilhar uma carreira acadêmica sem ter que se preocupar com dinheiro, conseguindo, assim, as condições adequadas para continuar seus estudos. A partir de diversos dados adquiridos em seu estudo, Mendel formulou as suas duas leis relativas à hereditariedade. A Lei da Segregação dos fatores e a Lei da Segregação Independente, conhecidas hoje como a primeira e segunda leis de Mendel.

Sabendo que a cor de uma determinada espécie apresenta caso de epistasia. Os indivíduos podem ter as cores azul, verde e amarela, e os genes “V” e “v“ estão relacionados com essa característica. O alelo V determina a cor azul; o alelo v determina a cor verde; e os alelos cc relacionam-se com a cor amarela e são epistáticos. No cruzamento entre dois indivíduos di-híbridos nasceram 320 indivíduos, e sabendo que os genes se segregam de forma independente, é CORRETO afirmar que a quantidade de indivíduos de cor amarela será provavelmente de:

A embriologia é a ciência que estuda o desenvolvimento de uma nova vida desde a fecundação até o nascimento. É importante lembrar, porém, que o desenvolvimento não cessa com o nascimento. Alguns sistemas orgânicos, como o nervoso, o digestório, o respiratório e o reprodutor ainda continuam se desenvolvendo mesmo após o nascimento.

Considerando o texto apresentado e seus conhecimentos, analise as afirmativas a seguir:
I- Na segmentação ocorrem diversas clivagens, que origina os blastômeros. A velocidade das clivagens é inversamente proporcional a quantidade de vitelo que se encontrado dentro da célula-ovo.
II- O primeiro estágio da clivagem é a mórula, na segunda e última etapa ocorre a blástula, onde ocorre a formação do celoma que está com líquido produzido pelas próprias células.
III- A nidação ocorre quando o blastocisto se fixa nas paredes do endométrio uterino. Se a nidação for bemsucedida iniciará a gestação do embrião.

Histologia é o ramo da ciência que estuda os tecidos biológicos, seja de animais ou plantas. Este ramo observa a formação, a estrutura e a função dos tecidos vivos. Os tecidos são formados a partir da junção de várias células. Então, a análise feita para este estudo é em escala microscópica, sendo para isso necessário o uso de equipamentos que permitam a observação das células. Aliás, a histologia somente conseguiu se desenvolver após a invenção do microscópio óptico.

A digestão celular está envolvida em processos fundamentais para a vida, como a manutenção da homeostase e a defesa dos organismos. Falhas da digestão intracelular acarretam doenças, como a doença de Gaucher. Nas doenças lisossômicas hereditárias acontece acúmulo de substâncias que não foram metabolizadas. Geralmente isso é decorrência da falta de uma enzima lisossomal.

Leia o poema de Manuel Bandeira para responder ao que se pede.
Desencanto
Eu faço versos como quem chora
De desalento... de desencanto...
Fecha o meu livro, se por agora
Não tens motivo nenhum de pranto.
Meu verso é sangue. Volúpia ardente...
Tristeza esparsa... remorso vão...
Dói-me nas veias. Amargo e quente,
Cai, gota a gota, do coração.
E nestes versos de angústia rouca,
Assim dos lábios a vida corre,
Deixando um acre sabor na boca.
Eu faço versos como quem morre.
(Teresópolis, 1912)
[A cinza das horas, 1917]

Considerando o poema, analise as afirmativas a seguir:
I- Desencanto pode ser considerado um metapoema pelo uso sofisticado da linguagem, podendo ser comprovado, por exemplo, pela construção metafórica do verso “Meu verso é sangue. Volúpia ardente...”.
II- O fazer poético em Desencanto explicita um eu lírico atravessado pela angústia e pelo sofrimento, o que pode ser confirmado, por exemplo, pelo verso “Eu faço versos como quem morre”.
III- O lirismo poético, observado em Desencanto, pode ser considerado uma das contribuições de Bandeira à estética modernista, especialmente na chamada primeira fase do movimento, que propunha uma ruptura radical com a cultura do passado.

Less than five hours' sleep a night linked to higher risk of multiple diseases
Getting less than five hours of sleep in mid-to-late life could be linked to an increased risk of developing at least two chronic diseases, finds a new study led by UCL researchers. The research, published in PLOS Medicine, analyzed the impact of sleep duration on the health of more than 7,000 men and women at the ages of 50, 60 and 70, from the Whitehall II cohort study.
Researchers examined the relationship between how long each participant slept for, mortality and whether they had been diagnosed with two or more chronic diseases (multimorbidity) -- such as heart disease, cancer or diabetes -- over the course of 25 years. People who reported getting five hours of sleep or less at age 50 were 20% more likely to have been diagnosed with a chronic disease and 40% more likely to be diagnosed with two or more chronic diseases over 25 years, compared to people who slept for up to seven hours. Additionally, sleeping for five hours or less at the age of 50, 60, and 70 was linked to a 30% to 40% increased risk of multimorbidity when compared with those who slept for up to seven hours.
Researchers also found that sleep duration of five hours or less at age 50 was associated with 25% increased risk of mortality over the 25 years of follow-up -- which can mainly be explained by the fact that short sleep duration increases the risk of chronic disease(s) that in turn increase the risk of death.
Lead author, Dr Severine Sabia (UCL Institute of Epidemiology & Health, and Inserm, Université Paris Cité) said: "Multimorbidity is on the rise in high income countries, and more than half of older adults now have at least two chronic diseases. This is proving to be a major challenge for public health, as multimorbidity is associated with high healthcare service use, hospitalizations and disability.
As people get older, their sleep habits and sleep structure change. However, it is recommended to sleep for 7 to 8 hours a night -- as sleep durations above or below this have previously been associated with individual chronic diseases. Our findings show that short sleep duration is also associated with multimorbidity. To ensure a better night's sleep, it is important to promote good sleep hygiene, such as making sure the bedroom is quiet, dark and a comfortable temperature before sleeping. It's also advised to remove electronic devices and avoid large meals before bedtime. Physical activity and exposure to light during the day might also promote good sleep."
As part of the study, researchers also assessed whether sleeping for a long duration, of nine hours or more, affected health outcomes. There was no clear association between long sleep durations at age 50 and multimorbidity in healthy people. However, if a participant had already been diagnosed with a chronic condition, then long sleep duration was associated with around a 35% increased risk of developing another illness. Researchers believe this could be due to underlying health conditions impacting sleep.
Jo Whitmore, senior cardiac nurse at the British Heart Foundation said:
"Getting enough sleep allows your body to rest. There are a host of other ways that poor sleep could increase the risk of heart disease or stroke, including by increasing inflammation and increasing blood pressure. This research adds to a growing body of research that highlights the importance of getting a good night's sleep."
The research was funded by the National Institute on Aging, part of NIH, UK Medical Research Council, the British Heart Foundation and Wellcome.
Study limitations
Researchers used self-reported data on sleep, which is likely to be subject to reporting bias, although using data on 4,000 participants whose sleep was measured via an electronic device confirm the findings. Meanwhile, data on sleep quality was only available for those aged 60 and 70.
The Whitehall II study only involves members of the civil service, who were all employed when recruited to the study and likely to be healthier than the general population.
