Which best describes lateral inhibition in the somatic sensory system? The frequency of action potentials along pathways from the site of a stimulus is increased by lateral inhibition. Lateral inhibition reduces the contrast between the frequency of action potentials generated at the center of a stimulus and the frequency of action potentials in surrounding pathways. The precision of locating a stimulus is enhanced by increasing the frequency of action potentials in nearby, parallel pathways. Stimuli of one particular modality in a region of the body block transmission of action potentials coding for other modalities generated in the same region of the body. The precision of locating a stimulus is increased by inhibiting signaling along nearby, parallel pathways.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
