Answer:
Experiment
Explanation:
For such an investigation an Experiment would be the better option. This is because in an experiment you would have both an experimental group and a control group. This would allow you to use fertilizer on one but not the other, therefore, providing seperate results that you can use to compare with one another. This ultimately helps you determine the actual effects that fertilizer has on the growth of plants, since the fertilizer would be the only variable in the experiment. An observational study would only allow you to observe the plants in a natural scenario, without interfering and seperating the plants into different groups with different environments.
Answer:
The change in color in the flowers is because the plant has absorbed the dyed water. After some hours, we can see that the water has ascended through the roots, the stem and reached the flower petals. We can see the water's path till it evaporates in a process called transpiration, which returns water to the atmosphere.
Explanation:
Plants absorb water and other nutrients so that they can live. When we add ink into the water, we can see the water's path from the roots, up the stem, the leaves, and the flowers. In the flowers, the water evaporates through the stomata. We call this process transpiration. The ink allows us to see that the water was in the petals, but it evaporates, leaving behind the ink. As water evaporates, the plant drinks more, which results in a more intense color in the petals.
The resort owners need to know that Coral reefs are important to the ocean because coral reefs provide a buffer, protecting our coasts from waves, storms, and floods. Corals form barriers to protect the shoreline from waves and storms. The coral reef structure buffers shorelines against waves, storms, and floods, helping to prevent loss of life, property damage, and erosion.
