Changes in muscle size due to steroids. dying your hair pink Newatch length due to a mutation A população de mosquitos de determinada área cresce a uma taxa proporcional à população atual e, na ausência de outros fatores, a população dobra a cada semana. Existem, inicialmente, 200000 mosquitos na área e os predadores comem 20000 mosquitos/dia. Determine a população de mosquitos na área em qualquer instante \( t \). 09) (UEPB 2014) Biólogos e Matemáticos acompanharam em laboratório o crescimento de uma cultura de bacté- rias e concluiram que esta população crescia com o tempo \( t \geq 0 \), ao dia, conforme a lei \( P(t)=P_{0} 5^{\lambda t} \), onde \( P_{0} \), é a população inicial da cultura \( (t=0) \) e \( \lambda \) é uma constante real positiva. Se, após dois dias, o nùmero ini- cial de bactérias duplica, entâo, após seis dias, esse número e: \( \begin{array}{llll}\text { a) } 10 P_{0} & \text { b) } 6 P_{0} & \text { c) } 3 P_{0} & \text { d) } 8 P_{0} \\ \text { e) } 4 P_{0}\end{array} \) Define the following terms: catalyst, enzyme, hemical digestion and denaturation. 2 a State what is meant by protein energy malnutrition. b Explain the differences between: i kwashiorkor and marasmus, and ii anorexia and bulimia. 3 Explain how obesity is a risk to one's health. 4 Suggest how governments could reduce the proportion of their populations who are obese.
