*SECTION A: THEMES FROM THE OLD TESTAMENTS* *ANSWER NUMBER 1A: The Call of Samuel* The call of Samuel is recorded in 1 Samuel 3. During this time, "the word of the LORD was rare; there were not many visions" (1 Samuel 3:1), indicating a period of spiritual decline in Israel. Samuel was the son of Elkanah and Hannah, born in answer to Hannah's fervent prayer. He was dedicated to the Lord and raised in the tabernacle at Shiloh under the guidance of Eli the high priest (1 Samuel 1:20-28). The Narrative: · One night, while Samuel was lying down in the house of the LORD where the ark of God was, the LORD called to him. · Samuel heard the voice but did not recognize it as God's. He ran to Eli three times, saying, "Here I am, for you called me". · Eli told him each time, "I didn't call you. Go back and lie down". · Eli then realized it was the LORD calling the boy and instructed Samuel to respond, "Speak, LORD, for Your servant is listening" (1 Samuel 3:9). · When the LORD called a fourth time, Samuel responded as instructed. · The LORD revealed to Samuel a message of judgment against Eli's house because of the sins of his sons, Hophni and Phinehas, and Eli's failure to restrain them (1 Samuel 3:11-14). · Samuel was afraid to tell Eli about the vision but eventually did so when Eli insisted. · Following this encounter, Samuel became established as a prophet of the LORD. "The LORD was with Samuel as he grew, and He let none of Samuel's words fall to the ground" (1 Samuel 3:19). · All Israel recognized that Samuel was a trustworthy prophet of the LORD.

(ii)Conjunction (Conjunctiva): Protects the eye by providing lubrication and preventing microbes from entering. (iii)Cornea: Acts as the outermost lens to refract (focus) light as it enters the eye. (4bi) TABULATE; UNDER; Transpiration: (i)Loss of excess water in form of water vapour from aerial parts of plants (ii)Occurs mainly through stomata, lenticels and cuticle of plants (iii)The water lost is not a metabolic waste product UNDER; Excretion; (i)Removal of metabolic waste products from the body of organisms (ii)Occurs through specialized organs like kidney, skin, lungs, gills (iii)Involves removal of toxic/used-up substances like urea, CO2, excess salts (4bii) (i)Shoulder joint; between head of humerus and glenoid cavity of scapula (ii)Hip joint: between head of femur and acetabulum of pelvic girdle (4c) ====================================================== QUESTIONS 1 (5a) TABULATE; UNDER; Root: (i)Grows downwards into the soil/positively geotropic (ii)Bears no leaves, flowers, buds or nodes (iii)Has root hairs for absorption of water and mineral salts UNDER; Stem: (i)Grows upwards or horizontally/negatively geotropic, positively phototropic (ii)Bears leaves, flowers, buds and nodes (iii)Has no root hairs; has buds in the axils of leaves (5aii) (i)Large and strong body/centrum: To support body weight. (ii)No facets for ribs: Unlike thoracic vertebrae. (iiii)Short, broad, flat spinous process: Projects horizontally backward for muscle attachment. (5bi) (i)Collenchyma; living cells with unevenly thickened walls, provides flexible support (ii)Sclerenchyma; dead cells with lignified thick walls, provides rigid support (iii)Xylem: conducts water and mineral salts and gives mechanical support (5bii) (i)Haemophilia: An inherited sex-linked recessive disorder in which blood fails to clot normally due to deficiency of clotting factors. (ii)Mutation: A sudden, random and heritable change in the DNA sequence or chromosome structure of an organism. (iii)Sex-linked character: A trait whose gene is located on a sex chromosome, usually the X-chromosome e.g. colour blindness, haemophilia. (5ci) (i)Arable farming. (ii)Pastoral farming. (iii)Mixed farming (5cii) (i)Drying/Dehydration. (ii)Refrigeration/Freezing. ======================================================

OBJECT 01-10: AECBAACADE 11-20: ECBDEBCDEA 21-30: CADBCDEBBD 31-40: DACEDDACBB 41-50: DBABEBEDAE 51-60: AAAEBDCBBB Complete!!! ====================================================== QUESTIONS 1 (1ai) Tolerance is the ability of an organism to survive, grow and reproduce within a range of environmental conditions such as temperature, pH, salinity, light intensity, etc. Outside this range, the organism cannot survive. (1aii) (i)Oxygen - from lungs to body tissues (ii)Carbon dioxide - from tissues to lungs for removal (iii)Nutrients - e.g. glucose, amino acids from small intestine to cells (iv)Waste products - e.g. urea to kidneys for excretion Other acceptable: Hormones, Heat, Antibodies, Water (1b) (i)Prophase - Chromosomes condense, spindle fibres form, nuclear membrane breaks down (ii)Metaphase - Chromosomes align at the equator/equatorial plate (iii)Anaphase - Sister chromatids separate and move to opposite poles (iv)Telophase - Nuclear membranes re-form, chromosomes uncoil, cytokinesis follows (1c) (i)Caste system/Social organization: Division of labour into workers, soldiers, queen and king for feeding, defense, reproduction and colony maintenance. (ii)Mound building: They construct large ventilated termitaria/mounds that regulate temperature and humidity for the colony. (iii)Fungus farming: Worker termites cultivate fungus gardens in the nest which serve as food, especially during dry seasons. (iv)Trophallaxis: Sharing of digested food mouth-to-mouth among colony members, and transfer of cellulose-digesting protozoa. (v)Swarming/Reproductive flight: Winged reproductives leave the nest at specific times to mate and start new colonies, avoiding overcrowding and inbreeding. ====================================================== QUESTIONS 2 (2ai) (i)Kidney - Mammals e.g. human (ii)Nephridium - Annelids e.g. Earthworm (iii)Malpighian tubule - Insects e.g. Cockroach (iv)Contractile vacuole - Unicellular organisms e.g. Amoeba, Paramecium (v)Flame cell - Platyhelminthes e.g. Planaria/Liver fluke (2bi) (i)Both are paired excretory organs that remove nitrogenous waste from the blood. (ii)Both are made up of tubules and are involved in osmoregulation. (2bii) TABULATE Under; Earthworm - Nephridium (i)Simple tubular structure, one pair per segment (ii)Opens to exterior by nephridiopore (iii)Excretes mainly ammonia Under; Mammals - Kidney (i)Complex bean-shaped organ with millions of nephrons (ii)Opens via ureter to urinary bladder (iii)Excretes mainly urea (2c) Stomata open and close due to changes in turgor pressure of guard cells. Opening: During the day, light stimulates accumulation of K+ ions and sugars in guard cells → water enters by osmosis → guard cells become turgid and bow outward, creating a pore. Closing: At night or under water stress, K+ ions and water leave guard cells → they become flaccid and collapse inward, closing the pore. ABA hormone also promotes closure. ====================================================== QUESTIONS 3 (3ai) -Protein: (i)Carbon. (ii)Hydrogen. -Carbohydrate: Carbon, Hydrogen, Oxygen (3aii) Diagram; (3aiii) (i)Birth rate/Natality (ii)Death rate/Mortality (3b) (i)Swarming: A sudden large-scale movement of organisms, especially insects like bees, locusts or termites, often for reproduction, migration or food. (ii)Epidemic: A sudden outbreak of a disease that spreads rapidly and affects a large number of people in a community or region at the same time. (3ci) Parthenocarpy: The development of fruit without fertilization, resulting in seedless fruits e.g. banana, pineapple. (3cii) (i)Barrier method - e.g. condom, diaphragm (ii)Hormonal method - e.g. birth control pills, implants. ====================================================== QUESTIONS 4 (4ai) (i)They are protein in nature, and they are highly specific in their action. (ii)They are reusable and remain unchanged after a reaction. (iii)They are temperature and pH sensitive. (4aii) (i)Pupil: Controls the amount of light entering the eye by dilating or constricting.
