The gap between the axon terminal of one neuron and the dendrite of another neuron is called the: MCQ with Answer and Explanation

Explanation:
Lichens represent mutualism where the fungal partner provides shelter, water, and minerals, and the algal or cyanobacterial partner provides food through photosynthesis. Both benefit. Parasitism is harmful to host; commensalism benefits one without affecting the other; predation involves one killing and eating the other. Lichens are bioindicators of air pollution, sensitive to SO₂. This association is obligate.

Explanation:
A synapse is the junction between two neurons (or neuron and effector) where the nerve impulse is transmitted from the presynaptic neuron to the postsynaptic neuron, usually via neurotransmitters. Axon carries impulses away from the cell body, dendrites receive signals, soma is the cell body. Synaptic transmission can be chemical or electrical.

Explanation:
Dengue fever is a mosquito-borne viral infection caused by the Dengue virus (four serotypes). It is primarily transmitted by the bite of an infected female Aedes aegypti mosquito (and Aedes albopictus). These mosquitoes typically bite during the day. Anopheles transmits malaria, and Culex transmits filariasis and Japanese encephalitis.
