Answer:
The correct answer is -
the neurotransmitters are broken down in the synapse
The presynaptic neuron absorbs the neurotransmitters
Explanation:
The termination of the neurotransmitters is essential as if they can cause harm by continuing the stimulus effect on the muscles or cells. To clean up these neurotransmitters there are two ways- Degradation of neurotransmitters with the help of enzymes in the synapses or synaptic cleft and the presynaptic neurons absorbs or suck up neurotransmitters. The neuron (presynaptic neuron) is that releases the neurotransmitter like dopamine, serotonin, is the one that re-uptake it.
This reuptake is done by transporter proteins that are are symporters in nature as these proteins pump neurotransmitters as well as ions back into the neuron.
I believe the answer is B.
Savanna and grassland is the correct answer. Those types of biomeds are characterized by the definition above, and two clear examples of these type of biomeds are India and certain part of Africa. Those types of biomeds create a unique life around them, when there is a lot of diversity and a lot of contrst between the season when it comes to life population, as often during the dry season some populations migrate towards more humid territories.
