(b) What was the function of the following apparatus? i) Pooter: A pooter is used for collecting small insects and other invertebrates from surfaces like rough bark or soil without direct handling. ii) Sweep net: A sweep net is used for catching flying insects from vegetation or in the air. iii) Chloroform: In biology practicals, chloroform is used as an anesthetic to immobilize or kill small organisms for examination or preservation. It is also a solvent for lipids and other organic compounds. 4. (b) Other than observation, name other two scientific skills developed by studying biology. Other scientific skills developed include: • Analysis • Classification Send me the next one 📸
