The sides of the double helix of the DNA are made up of sugar and phosphate backbone. The sugar is deoxyribose in case of DNA and ribose in case of RNA. The bridges are formed of the nitrogenous bases; adenine, guanine, thymine, and cytosine. RNA contains uracil n place of thymine.
Answer: The correct answer is -
D) A ---> B + C + energy.
Explanation:
Catabolic reactions can be described as one of the two types of metabolic reaction (other being anabolic) which occur within cell when complex organic molecules are broken down to form simpler, smaller molecules.
For example - Respiration, which involves glucose breakdown in order to form carbon dioxide and water. Generally they are type of hydrolysis reactions, which include water to break bonds present in complex molecules.
Large amount of energy is also released during these reactions.
Thus, option D) shows catabolic reaction.
The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.
If a living cell is placed in 1% sugar solution outside the cell would be hyper-tonic relative to the inside of cell. There would be a gradient between the inside cell and outside environment. Osmosis is the movement from higher to lower concentration, therefore the cell will lose water and it would dehydrate.
