Your colleague proposes to test the mechanism of ant navigation by placing a food source 7 meters (m) from the nest. she then takes ants from the nest and places them in a spot that is 4 m from the nest and 3 m from the food source. based on the previous data, where do you expect the ants to start searching for their nest on their return trip?

She placed a food source = 7 meters (m) from the nest
she then takes ants from the nest and places them in a spot that is 4 m from the nest and 3 m from the food source

The answer is that the ants are expected to start searching for their nest on their return trip "after they have traveled 3 m from the food source".

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
