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.

ocal and distant brain control in melanoma and nsclc brain metastases with concurrent radiosurgery and immune checkpoint inhibit
BartSMP [9]

Stereotactic radiosurgery (SRS) and immune checkpoint inhibitors (ICI) are increasingly used to treat brain metastases, however there is a paucity of prospective data on the effectiveness of these treatments in terms of cancer control.

Data from patients treated with SRS for non-small cell lung cancer (NSCLC) and melanoma brain metastases at a single facility from May 2008 to January 2017 were retrospectively examined. The impact of concurrent ICI within 30, 60, or 90 days of ICI administration on local control and remote in-brain control is examined using a parametric proportional hazard model. The regression model takes into account other patient and lesion characteristics as covariates and makes adjustments.

Chambers A and B are placed next to each other, but are separated by a film similar to a cell membrane. Chamber A contains 80% c
vodomira [7]

Answer:

b. Some carbon dioxide will move from chamber A to chamber B.

Explanation:

The two chambers are separated from each other by a separator that exhibits the properties of the cell membrane. It means that the separator film is semi-permeable in nature. The concentration of CO2 in the chamber A is 80%. This is relatively higher than its concentration in chamber B (20%). The concentration gradient will drive the passive diffusion of some of the CO2 from chamber A to chamber B so that the concentration becomes equal in both the chambers.
