While looking for food, an ant has lost its way back to its colony. With the help of which of these secretions would the ant be able to find its way back home?

Options

A. Thyroxine
B. Sebum
C. Adrenaline
D. Pheromone

Answer

To solve the question about how an ant can find its way back to its colony after getting lost, we need to analyze the options provided and determine which secretion would assist the ant in navigation.

**Step 1: Understand the Role of Secretions**
- Ants communicate and navigate their environment using chemical signals. These signals can help them find their way back to their colony.

**Step 2: Evaluate the Given Options**
1. **Thyroxine**: This is a hormone secreted by the thyroid gland in humans and other animals, primarily involved in regulating metabolism. It does not play a role in navigation for ants.

2. **Sebum**: This is an oily secretion from sebaceous glands in mammals that helps to keep skin and hair moisturized. It does not assist ants in finding their way back home.

3. **Adrenaline**: This hormone is released during stress or fear responses (fight or flight). It does not aid in navigation for ants.

4. **Pheromones**: These are chemical substances secreted by ants that serve as signals to communicate with other ants. They can mark trails to food sources or lead back to the colony.

**Step 3: Identify the Correct Answer**
- Among the options, **pheromones** are the correct choice. They are specifically used by ants to find their way back to their colony by following the chemical trails laid down by other ants.

**Final Answer**: The ant would be able to find its way back home with the help of **pheromones**.
