Question

write it! mel and jermaine learned from their science teacher that some of the trees in the small grove of orange trees on their schools campus might be suffering from citrus canker. this bacterial disease can affect any type of citrus tree and causes brown spots on the leaves and fruit of an infected tree. as the disease progresses, it can lead to loss of leaves, shoot dieback, and early fruit drop. jermaine and mel work with their science teacher to devise a plan to investigate and stop the spread of this disease. list two types of technology the students will need to conduct their research and how they will use those tools. explain the benefits and limitations of these two pieces of technology. give an example of a model mel and jermaine could create to help in their investigation, and explain a limitation to that type of model.

Explanation:

For the technology, a microscope can be used to examine leaf samples for bacteria up - close, its benefit is high magnification for detailed view, limitation is it can only observe small samples. A GPS device can be used to map the location of infected trees, benefit is accurate location tracking, limitation is it may have signal issues in some areas. For the model, a physical model of the grove using sticks and markers to represent trees can be created. Its limitation is that it is a simplified representation and may not account for all real - world factors like wind direction affecting disease spread.

Answer:

Two types of technology:

1. Microscope: Used to examine leaf samples for bacteria. Benefit - High magnification for detailed view. Limitation - Can only observe small samples.
2. GPS device: Used to map location of infected trees. Benefit - Accurate location tracking. Limitation - Signal issues in some areas.

Model example: Physical model of the grove using sticks and markers to represent trees. Limitation - Simplified representation, may not account for all real - world factors like wind direction affecting disease spread.
