Which of these structures is/are not properly matched with one of its/their functions?

nasopharynx: conduct air toward and from the larynx
pharyngeal tonsil: immune response
nasal conchae: create turbulence for incoming air
paranasal sinuses: surface for odor receptors

The correct answer is: paranasal sinuses: surface for odor receptors

Paranasal sinuses are” chambers” filled with air that surround the nasal cavities. There are four of them: maxillary sinuses (under the eyes); the frontal sinuses (above the eyes); the ethmoidal sinuses (between the eyes) and the sphenoidal sinuses  (behind the eyes). Paranasal synuses are lined with respiratory epithelium which has protective role.

Surface for odor receptors is the olfactory epithelium located in the nasal cavity.

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
