Answer : 2. "Cellulose"
Explanation :
Answer: B) Cellulose Explanation: Carbohydrates are also called as saccharides are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Carbohydrates are: * a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants * building blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body * components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATP Types: 1. Monosaccharides (e.g. glucose) and 2. Disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. 3. Other carbohydrate molecules are very large called Polysaccharides such as starch and cellulose.

Answer : 2. "Cytoplasm"
Explanation :
Answer: B) Cytoplasm Explanation: "Glycolysis" means the splitting of glucose. The first step of the process occurs in the cytoplasm of the cell and yields a small amount of energy (measured in units of ATP) and two molecules of pyruvate. The other steps occur in the mitochondria. It is an ongoing process as your cells have a constant need for energy.

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.
