Ovulation is the process by which a mature ovum (egg) is released from the ovary into the fallopian tube, making it available for fertilization by sperm.

(2aii) Oestrus Cycle:

The oestrus cycle is the recurring reproductive cycle in female mammals, characterized by phases of sexual receptivity (heat) and non-receptivity.

The heat period is the phase of the oestrus cycle when the female is sexually receptive and willing to mate.

(4a)

To calculate plant population:

• Area of land = 200 m × 150 m = 30,000 m²

• Spacing = 50 cm × 50 cm = 0.5 m × 0.5 m = 0.25 m² per plant

• Number of planting spots = Total area / Area per plant

= 30,000 m² ÷ 0.25 m² = 120,000 spots

• Germination percentage = 70%

• Expected plant population = 70% of 120,000 = 0.70 × 120,000 = 84,000 plants

Quarantine is a period of isolation or confinement of animals to prevent the spread of disease. It involves separating animals that may have been exposed to a disease from the rest of the herd or flock to prevent transmission.

(5aii)

Immunity refers to the ability of an animal’s body to resist infection or disease. It can be acquired through vaccination, previous exposure to a disease, or maternal antibodies passed from mother to offspring.

(5aiii)

A zoonotic disease is a disease that can be transmitted from animals to humans. Examples include rabies, brucellosis, and salmonellosis.

(i)Oxygen transport: Blood carries oxygen from the lungs to the body’s tissues.

(ii)Nutrient transport: Blood carries nutrients from the digestive system to the body’s tissues.

(iii)Waste removal: Blood carries waste products from the body’s tissues to the excretory organs.

(iv)Immune function: Blood contains immune cells that help fight infection and disease.

(6bi)

Pseudoruminants are animals that have a three-chambered stomach and a digestive system similar to ruminants, but with some key differences. They are able to digest and extract nutrients from plant-based foods, but their digestive system is not as complex as that of true ruminants.
