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).
Explanation:
<h2>
Nutritive Value if Sunflower Seeds are:--</h2>
100 grams of these seeds give around 585 calories of energy.
They have a good amount of fibre (8.5 g) and fats (51.5 g). Fats present are mostly polyunsaturated and monounsaturated; which are good fats
They are also rich in protein (20.77 g).

Rationale: A
sweet potato is equivalent to a serving of bread. One cup of skim or nonfat
milk is a serving of milk. A slice of avocado is equivalent to a serving of
fat. One teaspoon of mayonnaise is equivalent to a serving of fat.
