Um professor do Ensino Médio de uma tradicional escola de Juiz de Fora resolveu fazer uma aula prática sobre membrana plasmática com os seus alunos. Ele criou, em laboratório, células com as superfícies fluorescentes para o estudo do modelo proposto por Singer e Nicolson. Neste experimento, ele usou uma célula com a superfície fluorescente e observou-a em microscópio acoplado a um laser. O laser utilizado neste caso é capaz de degradar a fluorescência conjugada às moléculas na superfície celular. Iniciado o experimento, ele expôs um ponto específico da célula ao laser. Após cinco minutos de exposição da incidência do laser, observou que a região exposta perdia a fluorescência, mas o restante da célula continuava fluorescente. Entretanto, após uma hora de exposição, no mesmo ponto focal, toda a célula perdia a fluorescência. Baseado nesse experimento, responda à questão abaixo. Quais moléculas perderam a fluorescência e qual é o modelo evidenciado neste experimento?

Ответ:
Newton's law of universal gravitation is usually stated that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
