Answer: The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building.
Explanation:
The graph shows that the rate of photosynthesis increases with increased light intensity, other conditions being constant.
<h3>Photosynthesis and light intensity</h3>
From the graph, the rate of photosynthesis increases with an increase in light intensity.
At low light intensity, the photosynthesis rate increases with an increase in the concentration of carbon dioxide and level off at some point.
With medium light intensity, the rate of photosynthesis is about twice that of low light intensity under the same concentration of carbon dioxide. It also gradually levels off when the concentration of carbon dioxide reached a particular point.
The same trend applies to high light intensity. The rate of photosynthesis increased accordingly, much more than low and medium-intensity light.
Both light and carbon dioxide concentration can limit the rate of photosynthesis. When both factors are abundant, photosynthesis can be limited by other factors such as water, nutrient, etc.

Answer:
pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.
