Answer: WAGGLE DANCE is the dance that provides honey bees information about both the direction and distance of food.
Explanation:
Honey bees are flying insects that helps in the pollination of plants as they collect nectar and pollen from plants for food. As the name implies, they are known for the production of honey.
The honey bee dance helps in social organization of the honey-bees which is established by the living of all individuals within the colony and they show the mutual cooperation among the members of the colony, and exhibit the overlapping generations.
WAGGLE DANCE is the dance that provides honey bees information about both the direction and distance of food for the colony. It consists of two phases:
- the WAGGLE phase and
- return phase which occurs in a regular alteration pattern by foragers. It involves running through a small figure-eight pattern.
A chemical change must have occurred in investigation B step 2 because a change in color occurred.
<h3>What is a chemical change?</h3>
A chemical change is said to occur when a new substance has been formed. The markers of the occurrence of a chemical change are signs such as;
- Evolution of a gas
- Appearance of a solid
- Change of color
- Change of temperature
Now a physical change does not involve the formation of a new substance. Physical change would always involve the change of a substance from one form to another such as the melting of ice.
As such, in looking our for the steps in which a chemical change occurred we must look out for the properties of a chemical change as mentioned above.
Now, a chemical change must have occurred in investigation B step 2 because a change in color occurred.

Investigations were carried out in a science lab to explore the topic of chemical and physical changes. Investigation A Step 1. Add 5 tsp. salt to 100 ml warm water and stir until most or all of the salt is no longer visible. Step 2. Heat the salt solution on a burner until only a white solid remains. Investigation B Step 1. Mix 10 tsp. white sugar into 100 ml water and stir until most or all of the sugar is no longer visible. Step 2. Heat the sugar solution on a burner until the solution thickens and turns brown. In which step(s) did a chemical change most likely occur?
