c. our ability to detect odors from pheromones

d. the fact that different odorant molecules produce varied patterns of activity

ANSWER:

Step 1 of 2

Smells have the ability to evoke strong emotional and memory responses because the olfactory system is closely connected to brain centers responsible for processing emotions and memories. When we encounter a smell, the olfactory receptors in our nose detect specific odorant molecules, which then send signals to the olfactory bulb in the brain. From there, the information is processed in various brain regions, including the amygdala and hippocampus, which are known to be involved in emotional and memory processing.
