the answer is line graphs.Line graphs can also be used to compare changes over the same period of time for more than one group. brainliest plzzz.
 
        
             
        
        
        
One major risk is mutation. Diseases can mutate just has how we have genetic mutations. The bacteria in the cattle may become immune to the drugs over a long period of time, or mutate and become immune. As we try to fight it with more antibiotics, it may become immune to those as well, eventually creating a bacteria immune to most antibiotics, leaving us unable to fight it, especially in poorer areas, due to the fact that if we did create new antibiotics they would be more expensive than your common antibiotic, such as penicillin.<span />

She should investigate how temperature affects the rate of oxygen production. 
<h3>Photosynthesis</h3>
During photosynthesis, green plants make use of inorganic products in the form of water and carbon dioxide to synthesize carbohydrates. The reaction only happens in the presence of solar radiation and oxygen is evolved as a by-product.
The process involves a series of chemical reactions. However, the summary of the whole reactions is represented by the following equation:
carbon dioxide + water ----> glucose + oxygen
Thus, if Emily is to find out how temperature affects photosynthesis. She will need to use a plant as a case study. One factor that can easily be used to measure the rate of photosynthesis is oxygen production by plants. 
In other words, Emily will have to set up an experiment where a plant species will be subjected to the same environmental conditions, except temperature. Then, a suitable method will be used to measure the amount of oxygen produced. Any difference in the volume of oxygen produced can then be attributed to the effects of temperature.
