Explanation:

The choroid plexus (also known as plica choroidea) is a highly vascularized structure composed of capillaries covered by a layer of specialized epithelial cells, whose main function is to produce cerebrospinal fluid (CSF). The third ventricle is a cavity filled with CSF which is found between the two halves of the brain. The fourth ventricle is a cavity that contributes to the formation of the CSF-filled central canal which runs along the length of the spinal cord. The lateral ventricles are the two largest ventricles filled with CSF. The left ventricle and right ventricle are located in the left and right cerebral hemispheres, respectively. The interventricular foramen is a channel located between the lateral ventricles and third ventricle, thereby connecting these ventricles and thus allowing CSF to pass between them. The septum pellucidum is a double membrane structure located in the midline of the brain (i.e., between both cerebral hemispheres), which separates the frontal horns and bodies of the lateral ventricles in the midline. Finally, the cerebral aqueduct is a structure located within the midbrain (also filled with CSF) that connects 3rd and 4th ventricle.

youre right there are

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
