What are the central ideas of Cells? • What are cells? – Cells are the smallest basic unit of living things. • What do they do? – Cells take in raw materials and making new substances. • Why do they do this? – In cells‚ organelles carry out activities to keep the organism alive. – E.g. synthesising proteins and fats‚ releasing energy from glucose. What are the central ideas of Movement of Substances? • What processes describe how substances move from one region to another? –

Adaptation Definition: Adaptation is the process of how organisms develop special structures and internal processes to enable them to live in their environment. Definition: Adaptation is the process of how organisms develop special structures and internal processes to enable them to live in their environment. Organisms can be adapted in two ways: 1. Body structure (e.g. Small ears to reduce heat loss) 2. Body processes (e.g. Osmoregulation in salmon) There are several factors which

CELL DIVISION Important Formula #1 In case of animal cells‚ cytokinesis takes place through cell furrow (centripetal). Cytokinesis takes place in plants by the formation of cell plate (centrifugal). Important Formula #2 Meiosis causes reduction chromosome number‚ so it is also known as reduction division. CELL RESPIRATION Important Formula #1 For oxidative phosphorylation‚ 2.5 ATP are produced per NADH and 1.5ATP per FADH2. (Approx.) Important Formula #2 Non-germinating live seeds and

There is a 25% chance that Allison and Tim will have a baby boy who is heterozygous for Tay-Sachs. b. No‚ the baby boy will not have Tay-Sachs he will be a carrier for the disease. The boy would only have the disease if he was homozygous recessive. | X | Y | X | XX | XY | X | XX | XY | 1:2 1:2 | T | t | T | TT | Tt | t | Tt | tt
