Question: Q: What is required to break down and build up molecules and to transport molecules across plasma membranes? Read this paragraph and choose the correct option from the provided answers: Inside every cell of all living things, energy is needed to carry out life processes. Energy is required to break down and build up molecules and to transport molecules across plasma membranes. All life's work needs energy. A lot of energy is also simply lost to the environment as heat. The story of life is a story of energy flowits capture, its change of form, its use for work, and its loss as heat. Energy, unlike matter, cannot be recycled, so organisms require a constant input of energy. Life runs on chemical energy. Where do living organisms get this chemical energy?. Choices: - salt - electricity - calcium - energy A:
Answer: energy

Question: Q: Rust is an example of the reaction of oxygen with what? Read this paragraph and choose the correct option from the provided answers: Reaction with Elements Oxygen reacts directly at room temperature or at elevated temperatures with all other elements except the noble gases, the halogens, and few second- and third-row transition metals of low reactivity (those with higher reduction potentials than copper). Rust is an example of the reaction of oxygen with iron. The more active metals form peroxides or superoxides. Less active metals and the nonmetals give oxides. Two examples of these reactions are: 2Mg(s) + O 2(g) 2MgO(s) P 4(s) + 5O 2(g) P 4 O 10(s) The oxides of halogens, at least one of the noble gases, and metals with higher reduction potentials than copper do not form by the direct action of the elements with oxygen. Choices: - fuel - carbon - coal - iron A:
Answer:
iron
