Answer:
Produced by the choroid plexus -T.This is the major secretion site.It is also produced in smaller quantities in the interstitial compartment.
Blocks blood toxins from brain tissue-F, that is the job of the blood brain barrier(BBB).
Supplies oxygen to the brain tissue-T.This gas is dissolved in the CSF together with CO2 for distribution among nervous tissues by the CSF
Maintains the concentration of glycine surrounding the brain-T
Found in the ventricles of the heart and brain-False,it does not reach the heart ventricles.This are occupied by blood.
Prevents concussions-T
Produces antibodies in response to antigen exposure in the brain tissue-False.These are produced by the B-cells, not by in the CSF,based on the specif antigen stimulation.
Effectively decreases the brain's weight-T It reduces the weight of the brain.This is done by the buoyancy it provided for the brain.
Compared to levels in the blood plasma, the CSF is higher in glucose-F.This is wrong, the glucose of the blood plasma is higher.But equal sodium ion,more chloride in CSF, and less protein.It s levels is a relefection of blood glucose.Although it may lag 2-4hrs in the CSF.
It prevents concussion,(T)and and the contraction of cardiac muscles propels its movement(T).

<em>In </em><em>the </em><em>2</em><em>0</em><em>0</em><em>-</em><em>p</em><em>l</em><em>u</em><em>s</em><em> </em><em>years </em><em>since </em><em>the </em><em>industrial </em><em>revolution </em><em>began,</em><em>concentration </em><em>of </em><em>carbon </em><em>dioxide </em><em>in </em><em>the </em><em>atmosphere </em><em>has </em><em>increased </em><em>due </em><em>to </em><em>human </em><em>actions.During </em><em>this </em><em>time,</em><em>the </em><em>pH </em><em>of </em><em>surface </em><em>ocean </em><em>waters </em><em>has </em><em>fallen </em><em>by </em><em>0</em><em>.</em><em>1</em><em> </em><em>pH </em><em>units.This</em><em> </em><em>might </em><em>not </em><em>sound </em><em>like </em><em>much,</em><em>but </em><em>the </em><em>pH </em><em>scale </em><em>is </em><em>logarithmic,</em><em>so </em><em>this </em><em>change </em><em>represents </em><em>approximately </em><em>a </em><em>3</em><em>0</em><em> </em><em>percent </em><em>increase </em><em>in </em><em>acidility.</em>
