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:
At least 17 elements<span> are known to be essential nutrients for plants. In relatively large amounts, the soil supplies nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur; these are often called the macronutrients. Hope this helps. Have a nice day.</span>
The rate of change in velocity is known as acceleration
Answer:
The genus and the species
Explanation:
Carolus Linnaeus, who is referred to as the FATHER OF TAXONOMY proposed a principle used in naming organisms till date. This system of naming organisms is called BINOMIAL NOMENCLATURE SYSTEM, which comprises of two Latin names for each organisms.
The binomial nomenclature gives an organism its scientific name using the GENUS of such organism and it's SPECIFIC NAME. For example, dogs have their scientific name as Canis familiaris, this means that:
Canis - Genus
Familiaris - species
