B. Apply Scientific Reasoning If you were a carrot farmer, what concentration of auxin
should you apply to your fields to produce the largest carrot roots?



Answer :

As a carrot farmer aiming to produce the largest carrot roots, you should consider the concentration of auxin you apply to your fields. Auxin is a plant hormone that plays a significant role in root development. Here are steps you can follow to determine the appropriate concentration of auxin: 1. **Understand the Role of Auxin:** Auxin is a hormone that influences root growth. Higher concentrations of auxin can promote root growth, but excessive amounts may have negative effects. 2. **Start with Low Concentrations:** Begin by applying a low concentration of auxin to a small area of your field. Monitor the growth of the carrot roots in this area to observe how they respond to the hormone. 3. **Gradually Increase Concentration:** If the carrots show positive growth response to the initial concentration, you can gradually increase the auxin concentration in a controlled manner. 4. **Monitor Growth and Health:** Continuously monitor the growth and health of the carrot plants as you adjust the auxin concentration. Look for signs of healthy root development, such as increased size and length of roots. 5. **Optimize Concentration:** Find the concentration of auxin that results in the largest and healthiest carrot roots. It's important to strike a balance between promoting growth and avoiding negative effects of excessive auxin. 6. **Consider External Factors:** Keep in mind that environmental conditions, soil quality, and carrot variety can also influence root growth. Adjust the auxin concentration based on these factors to optimize carrot root development. By following these steps and carefully monitoring the response of the carrot plants to different auxin concentrations, you can determine the ideal concentration to produce the largest carrot roots in your fields.
