BRAINLIESTTTT ASAP!!!<br><br> What roles do society, politics, and economics play in science?
ser-zykov [4K]
So what roles do society, politics, and economics play in science?Economics determines how much money is available to fund scientific research. Certain federal grants come directly out of the national economy, which determines if certain research projects can continue or are cut off.Politics affect science by passing some bills that directly affects science, congressmen can determine whether those funds from the economy will be used for research or not. Just a side note: wealthy lobbyists control alot of what politicians do, by donating millions into their election campaigns. Society affects science by our citizens democratically electing those politicians that we think will or will not endorse scientific research projects. For example, embryonic stem cell research has been under fire by conservatives for taking future babies' cells to study. Liberals, however, tend to be in favor of change and new advances scientifically
_____________________________________________________________

if you need it shorter "Society, made up of the country's citizens, can influence science by electing politicians (president and congressmen); the politicians can then affect the economic funding of scientific research, either by increasing or decreasing government grants to scientific projects."

The output region is the site of ______________________.
tester [92]

Answer:

The correct answer is option C (voltage gated Na+ channels).

Explanation:

Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.

The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.  

At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.

Thus, option C (voltage-gated Na+ channels) is the correct answer.
