(a) Disease-causing organism: Ranikhet disease is caused by the Newcastle Disease Virus (NDV).
(b) Commonly Found in: It affects poultry birds such as chickens, ducks, and turkeys.
(c) One symptom: Birds infected with Ranikhet disease show respiratory distress, coughing, and sneezing. Neurological symptoms like twisted necks may also occur.
(d) One control measure: Vaccination is the most effective measure to prevent Ranikhet disease in poultry. Proper sanitation and biosecurity measures should also be maintained.
Match List-I with List-II.\[\begin{array}{|c|c|} \hline \text{List-I (Animal)} & \text{List-II (Breed)} \\ \hline \text{(A) Buffalo} & \text{(I) Sunandini} \\ \hline \text{(B) Cow} & \text{(II) White Leghorn} \\ \hline \text{(C) Poultry} & \text{(III) Toggenburg} \\ \hline \text{(D) Goat} & \text{(IV) Nili-Ravi} \\ \hline \end{array}\]Choose the correct answer from the options given below:
In the adjoining figure, \( AP = 1 \, \text{cm}, \ BP = 2 \, \text{cm}, \ AQ = 1.5 \, \text{cm}, \ AC = 4.5 \, \text{cm} \) Prove that \( \triangle APQ \sim \triangle ABC \).
Hence, find the length of \( PQ \), if \( BC = 3.6 \, \text{cm} \).
