<span>D is the correct answer. Metabolism is formed of two processes, anabolism, which builds new structures, for example, proteins, and catabolism, which breaks down existing structures. Catabolism breaks down large molecules like lipids into smaller ones like fatty acids.</span>
Process A → Decaying / Decomposition
Process B → Nitrification
The root nodules are important in the nitrogen cycle as they help in intaking of nitrogen and other minerals like phosphorous, potassium, sodium etc. from the soil.
Hope it helps you
Brine rejection is a process that occurs when salty water freezes. The salts do not fit in the crystal structure of water ice, so the salt is expelled.
There are four stages of DNA, primary, secondary, tertiary, and quaternary. at the TERTIARY level, DNA finally becomes a fully functional 3D shape. at the tertiary level, a huge amount of bonding occurs, including ionic and hydrogen bonding.
Polysaccharides are present in all living organisms where they carry out one or more of their diverse functions. While there is no specific category or definition of a complex polysaccharide, most are structurally complex. Polysaccharides contain 1–5 different monosaccharide (sugar) units. The different sugar units may have different anomeric configurations and/or be joined by different glycosidic linkages. Polysaccharides may be linear or branched. Branches may be short saccharide units on a linear backbone or the molecule may have a branch-on-branch structure; in either case, the branches may be isolated or clustered. Polysaccharides may contain non‐carbohydrate groups. Esters or cyclic acetal groups, when present, can be removed by appropriate treatments. All polysaccharides are polydisperse, i. e., are present in a range of molecular weights rather than having a single molecular weight
