The answer is tropical savanna. The region’s ecosystem is characterized by tall grasses,
shrubs, and a scattered distribution of trees (especially acacia trees).
Large regions of tropical savanna extend through the nations of Botswana,
Namibia, and Kenya in Africa. Savannas are also characterized
by seasonal water availability, with the majority of rainfall confined to one
season. They are frequently found in transitional zones between forest and
desert or grassland.

Answer:
The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.
Explanation:
The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.
Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.
During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.
