True. Metamorphic rocks are pre-existing rocks that have been modified through the exposure to unusual temperatures and/or pressures. It has been used for blackboard, roofs, sidewalks, floors, and marble is an example of a metamorphic rock that is used to make floor tiles, countertops and it is carved into statues and was used extensively in the building of the Roman Colosseum and other historic buildings.
Hydrochloric Acid (HCl) is produced by the stomach and has the job of breaking down proteins. If you make plenty of HCl, then the body can adequately digest protein. If not, protein digestion is compromised.

The main difference between Exponential growth and Logistic growth is that logistic growth takes into account carrying capacity. On a graph, logistic growth levels off as it nears carrying capacity while exponential growth does not.
Exponential growth involves a positive feedback loop and Logistic growth involves a negative one.

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.
