Biology SPM 2011 Predictions and Tips

Since teacher in school didn't quite do any spotting or what for us, here's one based on State Trials and online predicitons. Thanks to Mei Khay for compiling the State Trials. "HOtness" arranged in order! Heh.

Do NOT read these only, read ALL, FOCUS on these.

Reproduction and Growth (HOT!)

• - Double Fertilisation (then seeds and fruit)
• - Embryo Sac
• - Primary/Sec growth
• - Menstrual Cycle
• - Growth curve
• - Twins
• - Contribution to Science

Locomotion and Support (Hot!)

• - Antagonistic muscles
• - Movement of forearm to bend and straighten
• - Adaptations of fish to swim
• - Movements of birds,earthworms and grasshoppers
• - Mechanism of locomotion of fish
• - Musculoskeletal diseases
• - Healthy Musculoskeletal System
• - Support in water plants

Nutrition

• - Alimentary canal in organisms
• - Determine vitamin C content & energy value
• - Digestion (Focus on stomach)
• - Assimilation
• - Balanced diet
• - Food pyramid

Coordination and Response

• - Endocrine + Nervous System
• - Homeostasis (temperature/blood pressure)
• - Plant hormones (auxins)
• - Muscles,tendons,ligaments,joints on walking/running
• - Voluntary action (neurones)

Inheritance and Variation

• - Mendel's First Law
• - Benefits and risks in agriculture
• - Mutation
• - Type, differences and causes of variation
• - Meiosis(new combination of genes)

Ecosystem (It'll sure come out, as usual)

• - Deforestation
• - Thinning of Ozone Layer/Acid rain
• - Effects of human activities
• - Eutrophication
• - Preserve,conserve environment
• - mangrove trees
• - Succession (Colonisation)
• - Production of crops
• - Overuse of fertilisers

Transport

• - Types of immunity
• - Water transport in plants
• - Interstitial fluid
• - Lymphatic system

Enzymes

• - Extracellular enzyme
• - Carbohydrates
• - pH changes(enzyme activity)

Respiration

• - Aerobic, anaerobic respiration
• - Regulatory mechanism in respiration (C02)
• - Breathing mechanism of fish and humans

Paper 3 Experiments

- Transpiration Factors, leave numbers/wind (HOT!)
- Movement of substances across the plasma membrane
- Energy value of food sample
- Effect of water intake onto urine formation
- Population size of rats
- Function of phloem tissue
- Effect of glucose concentration on anaerobic (yeast)

LOL All the very Best! XD
