Fatty acids are hydrocarbons with a carboxylic acid group (-COOH) attached, so they are hydrophobic (don't mix with water) at one end and hydrophilic (water soluble at the COOH end)
Simple carboxylic acids don't have a long enough hydrocarbon chain to have this characteristic, e.g. CH3COOH acetic acid
Typical fatty acids found in nature include stearic acid with an 18-carbon chain
CH3-(CH2)16-COOH
When the mealworm is touched with a feather, it wiggles. This response is a reflex because it happens automatically. Also, mealworm behaviors could be instinctive. When bran flakes are placed in the petri dish with the mealworm, it moves toward the bran flakes. This response is instinctive because it involves recognizing the stimulus and <span>then acting upon behaviors until they are all performed. </span>I hope this is the answer that you were looking for.
