one difference between bulimia and binge - eating disorder (bed) is that _.
o purging behavior occurs with bulimia but not bed
o damage to the teeth and throat occur more frequently in bed than bulimia
o people with bulimia show an insensitivity to hunger signals but people with bed show an excessive perception of hunger signals
o all these options are correct.

Explanation:

• For the first question:
• Receptors in the stomach and intestines (e.g., stretch receptors) send signals related to fullness. Hormones (like ghrelin - hunger hormone, leptin - satiety hormone), enzymes, and other bodily chemicals play crucial roles in regulating hunger and eating. Psychosocial factors (such as stress, cultural food norms, emotional states) also influence eating behavior. So all these factors influence eating and hunger.
• For the second question:
• In bulimia nervosa, purging behavior (e.g., self - induced vomiting, excessive use of laxatives) is a key feature, while in binge - eating disorder (BED), purging is not present. Purging in bulimia can lead to damage to teeth (from stomach acid in vomiting) and throat more frequently than in BED (where purging is absent). Also, the perception of hunger signals is not a typical differentiating factor in the way described in the third option. So the main difference is that purging behavior occurs with bulimia but not BED.

Answer:

• First question: All these influence eating and hunger.
• Second question: purging behavior occurs with bulimia but not BED.
