2) a. lower b. Longer c. shorter
A. Longer
C. Shorter
The sound of a police siren that is moving away has shorter wavelengths, and one that is approaching has longer wavelengths.
Explanation;The pitch of the sound heard depends on the frequency of the sound wave. A higher frequency corresponds to a high pitch. Therefore, when the police siren is approaching an observer, the observed frequency increases and thus the observer hears a higher pitch.Conversely, when the police siren is moving away from an observer, then the frequency decreases and thus, the pitch of the sound heard is lower.A higher frequency corresponds to a shorter wavelength, therefore, the shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound.Through what openings of the nose does inhaled air enter the upper respiratory tract? anterior nares posterior nares nasal cavity nasopharynx

Answer:
D. Parietal lobe

The sensory pathway is an ascendent pathway that carries information from the periphery to the brain, in this case the sensation is the heat, which is felt at the finger, the sensation then travels upwards and enters the spinal cord at the cervical level and crosses the midline to the opposite side, then continues to the brain stem and finally to the parietal lobe, areas 3, 1, 2 (primary somatosensory area) where the information is processed.
