List these events in the correct order for CSF flow in the CNS. a: CSF flows into the arachnoid villi b: CSF enters the blood c: CSF flows through the cerebral aqueduct to the fourth ventricle d: CSF flows into the subarachnoid space e: CSF is produced by the choroid plexus

CSF is produced by the choroid plexus > CSF flows through the cerebral aqueduct to the fourth ventricle> CSF flows into the subarachnoid space > CSF flows into the arachnoid villi > CSF enters the blood.

Explanation:

Cerebrospinal Fluid is the fluid of the brain and spinal cord and allows for buoyancy of the brain, protects the brain from injury and mechanical stress, excretes metabolic wastes from the brain. Cerbrospinal fluid is formed by the choroid plexus of the lateral, third and fourth ventricles The CSF flows from the lateral ventricle to the third ventricule through the interventrricular foramen and from the third ventricle through the cerebral aqeduct to the fourth ventricule. It then flows into the subarachnoid space. Absorption of the CSF occurs by the actions of the arachnoid villi as the CSF flows into it. The CSF then flows into the blood due to the concentration gradient between the pressures of CSF in the venous blood and in the arachnoid villi.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

your answer is rna to the question.
