Answer : 1. "Younger people generally have a slower metabolism than adults."
Explanation :
Answer: A) Younger people generally have a slower metabolism than adults. Explanation: Metabolism is the set of life-sustaining chemical transformations within the cells of organisms. The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes, the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes. Younger people have faster metabolism than adults. Hence, the given statement 'Younger people generally have a slower metabolism than adults' is FALSE.

Answer : 1. "Sulphur dioxide"
Explanation :
Answer: A) Sulphur dioxide Explanation: Air pollutants are solid particles, gases, and liquid droplets in the air that can adversely affect ecosystems and the health of humans. Major ambient air pollutants include toxic metals, polycyclic aromatic hydrocarbons, benzene, particulate matter (PM), nitrogen oxides, sulfur oxides, carbon monoxide, and ozone. Power plants, factories, and vehicle and air traffic are the most important anthropogenic sources of air pollution. In addition, natural sources such as wildfires and volcanic activity contribute to ambient air pollution.
