Which branch of biology deals with the study of bees? MCQ with Answer and Explanation

Explanation:
Vernalization is the process by which many plants, particularly biennials and winter annuals (like winter wheat, cabbage, and carrots), require exposure to a prolonged period of low temperature (cold treatment) before they can initiate flowering. This prevents the plant from flowering in the autumn, ensuring it survives the winter and flowers in the spring or summer. The cold stimulus is perceived by the apical meristem or the germinating seed.

Explanation:
Kala-azar, also known as visceral leishmaniasis, is caused by the protozoan parasite Leishmania donovani. It is transmitted by the bite of the infected female sandfly (Phlebotomus). The disease affects internal organs, particularly the liver, spleen, and bone marrow, causing prolonged fever, weight loss, and enlargement of the liver and spleen. Trypanosoma brucei causes sleeping sickness, and Plasmodium causes malaria.
