Ans. (D). lipids weigh less and store more energy (gram for gram) than carbohydrates.
Lipids represent a class of biomolecules, made up of long hydrocarbon chains. Lipids, such as triglycerides act as major energy storage sources in plants and animals.
Lipids weigh less and contain more carbon atoms per gram as compared to carbohydrates as in carbohydrates, more oxygen is present. Due to this, lipids provide about 9 kcal (kilocalories) per gram, while carbohydrates provide about 4 kcal per gram.
Hence, it is advantageous for migratory animals to store energy in the form of lipids instead of carbohydrates.
Thus, the correct answer is option (D).
Answer:
Totipotent - Able to differentiate into any type of cell of the human body or of the placenta. For example, fertilized egg cells and the cells from the egg’s first few divisions.
Pluripotent - From totipotent cells, able to differentiate into almost any type of cell of the human body. For example, blastocyst cells
Multi potent - Can develop into more than one type of cell, but more limited than pluripotent cells. For example adult stem cells and cord blood stem cells
Unipotent - Can only differentiate in a single lineage. Skin cells are the most abundant type of these.
