Explanation:
Lymphatic filariasis, commonly known as elephantiasis, is a parasitic disease caused by nematode worms, primarily Wuchereria bancrofti. The infective larvae (microfilariae) are transmitted to humans through the bite of an infected female Culex mosquito (primarily Culex pipiens fatigans). The adult worms lodge in the lymphatic vessels, causing severe inflammation, blockage, and the characteristic massive swelling (elephantiasis) of the limbs and genitals. Anopheles transmits malaria, Aedes transmits dengue.

Explanation:
The nomenclature for restriction enzymes is based on the genus, species, strain, and order of discovery of the source bacterium. In EcoRI: 'E' stands for the genus Escherichia, 'co' stands for the species coli, 'R' stands for the strain RY13, and 'I' indicates that it was the first restriction enzyme isolated from this particular strain. This systematic naming convention helps scientists identify the exact source of the enzyme.

Explanation:
The midbrain (mesencephalon) is the uppermost part of the brainstem. Its dorsal surface features four rounded elevations called the corpora quadrigemina (meaning 'four bodies'). These consist of two upper, larger swellings called the superior colliculi, which are reflex centers for visual movements (like tracking moving objects), and two lower, smaller swellings called the inferior colliculi, which are part of the auditory pathway and relay sound information to the thalamus.
