theory states that: i. All organisms are made of organelles / cells. ii. All existing cells are produced by other living / dead cells. iii. The atom / cell is the most basic unit of life. 7. Cell theory is one of the great unifying theories of biology / chemistry. Main idea: Prokaryotic cells lack a nucleus and most internal structures of eukaryotic cells. 8. For each of the following cell characteristics‚ place a check mark in the appropriate box or boxes to indicate whether it is a characteristic

* Biology Investigation 3.1 Porcellio Scaber (Slater‚ Woodlouse) Task 1 The crustacean Porcellio Scaber‚ or more commonly known as the woodlouse‚ is a species usually found in leaf litter or in fallen trees and bark. It feeds on detritus like many other isopods of its type‚ and is generally predated on by small mammals‚ lizards and some insects. The woodlouse habitat reflects its need to avoid warm and dry areas. The woodlouse is prone to desiccation (drying out) due to its body’s large surface

Biology Digestion IA 13/03/2013 Jason Gao Rationale: Digestion is the chemical breakdown of food into smaller components that are more easily absorbed. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones. When food enters into stomach‚ gastric juice starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. The pH value of hydrochloric in the stomach
