From the perspective of the recipient of the signal, in

what ways do pheromones differ from other odorants?

Short Answer

Expert verified

Pheromones can have immediate physiological and behavioural impacts on their recipients despite the fact that they may not be cognizant of them.

Step by step solution

01

Step 1. Introduction 

The mucosa at the back of the nasal cavity, the olfactory epithelium, is where odorants (odour molecules) dissolve after entering the nose. In the back of the nasal cavity of humans, the olfactory epithelium is a cluster of specialised olfactory receptors that covers an area of about 5 cm².

02

Step 2. Explanation 

Remember that neurons make up sensory cells. When specific molecules from the environment are bound by an olfactory receptor, which is a dendrite of a specialised neuron, the receptor reacts by sending impulses straight to the brain's olfactory bulb. There are around 12 million olfactory receptors in

How does the structure of the ear allow a person to determine where a sound originates?

Cochlear implants can restore hearing in people who have a nonfunctional cochlea. The implant consists of a microphone that picks up sound. A speech processor selects sounds in the range of human speech, and a transmitter converts these sounds to electrical impulses, which are then sent to the auditory nerve. Which of the following types of hearing loss would not be restored by a cochlear implant? a. Hearing loss resulting from absence or loss of hair cells in the organ of Corti. b. Hearing loss resulting from an abnormal auditory nerve. c. Hearing loss resulting from fracture of the cochlea. d. Hearing loss resulting from damage to bones of the middle ear.

A satellite is launched into space but explodes after exiting the Earth’s atmosphere. Which statement accurately reflects the observations made by an astronaut on a space walk outside the International Space Station during the explosion? a. The astronaut would see the explosion, but would not hear a boom. b. The astronaut will not sense the explosion. c. The astronaut will see the explosion, and then hear the boom. d. The astronaut will feel the concussive force of the explosion, but will not see it.
