Name an organism where true regeneration occurs

Answer:Planaria (a flatworm) is a classic example of an organism that exhibits true regeneration. If cut into multiple pieces, each fragment can regenerate into a complete new organism, developing all the missing body parts including head, tail, and internal organs. Other examples include Hydra and starfish, which also demonstrate remarkable regenerative abilities.

Name the preservative solution used to preserve biological specimens in museums.

Answer:Formalin (typically a 4-10% formaldehyde solution in water) is the most commonly used preservative for biological specimens in museums. It prevents decay by killing bacteria and fungi, and it fixes tissues by cross-linking proteins, thereby maintaining the structural integrity of specimens for long-term storage and study.

BiologyClass 11CBSE

What is metabolism?

Answer: Metabolism is the sum total of all chemical reactions occurring within the cells of a living organism. It includes two main processes: Catabolism: Breaking down complex molecules into simpler ones, releasing energy Anabolism: Building complex molecules from simpler ones, consuming energy Metabolism is considered a defining feature of life, as no non-living object exhibits metabolic activities.
