Which may lead to lower productivity because of a lack of incentives?
LekaFEV [45]
I believe the answer is Government subsidies. A subsidy is the form of cash payment or a tax reduction. It is normally given to remove some type of burden, and it is often considered to be in the overall interest of the public, given to promote a social good or economic policy. Tax subsidy; the government can create the same outcome through selective tax breaks as through cash payment. For example, suppose a government sends monetary assistance that reimburses 15% of all health expenditures to a group that is paying 15% income tax. Tax subsidies are also known as tax expenditures.

Which of the following ways are leftover neurotransmitters cleaned up if they
Alisiya [41]

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.
