Which of the following types of neurons are replaced throughout adult life?
a) retinal ganglion cellsb) auditory outer and inner hair cellsc) retinal bipolar cellsd) olfactory receptor cells

D) olfactory receptor cells

Explanation:

The olfactory receptor neurons are located in the nasal cavity, they have dendrites that go all the way to the mucus. In vertebrates the olfactory system has the parcularity of performing neurogenesis and the replacement of degenerating receptor neurons through all the adult life.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
