- Easy root penetration
Specimen F – Mammalian Oesophagus and Stomach
This specimen represents part of the digestive system of a mammal.
Functions include:
- Transportation of food
- Temporary storage of food
- Digestion of proteins
- Secretion of digestive enzymes
Specimens G and H – Parasitic Plant and Host Plant
These specimens demonstrate parasitism.
Parasitism is a biological relationship where one organism benefits while the other is harmed.
Examples:
- Mistletoe
- Dodder
Likely questions may focus on:
- Type of relationship
- Advantages to parasite
- Effects on host plant
Specimen J – Evaporated Milk
Milk contains:
- Protein
- Fat
- Sugar
- Minerals
Milk is commonly used in food tests.
Specimen K – Fresh Fish
Fish belongs to the class Pisces.
Adaptive features include:
- Streamlined body
- Fins for movement
- Gills for respiration
- Scales for protection
Economic Importance:
- Source of protein
- Source of income
- Export commodity
Specimen L – Dry Maize Grain
Maize grain is a cereal crop rich in carbohydrates.
Uses include:
- Human food
- Livestock feed
- Industrial processing
Specimen M – Tomato Paste
Tomato paste is a processed food product.
It is preserved to increase shelf life and reduce spoilage.
Specimen N – Fresh Tomato Fruit
Fresh tomato is rich in:
- Vitamin C
- Water
- Minerals
- Antioxidants
Specimen P – Rotten Tomato Fruit
Rotten tomato demonstrates food spoilage caused by microorganisms such as fungi and bacteria.
Candidates may be asked to compare Specimens N and P.
Specimen Q – Thermometer
Used for measuring temperature.
Applications include:
- Laboratory experiments
- Weather studies
- Medical diagnosis
Specimen R – Metre Rule
Used for measuring length and distance during practical activities.
