A neurotransmitter is a chemical substance that facilitates communication between nerve cells (neurons) in the brain and throughout the nervous system. These molecules play a crucial role in transmitting signals across synapses, connecting neurons and enabling them to communicate with one another. Neurotransmitters are essential for various physiological processes, including mood regulation, cognition, and motor functions.

Drought-resistant crops are specifically bred or genetically modified plants that can withstand periods of low water availability, thus playing a crucial role in sustainable agriculture, especially in arid and semi-arid regions. As climate change exacerbates water scarcity, the development and adoption of drought-resistant crops are increasingly vital for food security and agricultural resilience.
