Of the steps included in the scientific method, Shameka is performing step five, which is to<u> test your hypothesis by performing an experiment</u>.
The scientific method is the globally accepted process by which to make scientific claims. This method includes seven steps which are:
- Ask a question
- Do research
- Create a hypothesis
- Design an experiment to test the hypothesis
- Perform the experiment
- Study the results and make a conclusion
- Communicate the results to your peers.
The question states that Shameka is <u>gathering samples from nearby water sources</u>, therefore she is in the process of testing her hypothesis through experimentation, which corresponds to step 5 of the scientific design.

Hope this helps!
Answer:
The correct answer would be option C.
Plants evolved different methods to prevent or reduce the effects of photorespiration.
The C3 plants are the most common plants which do not have any special methods or physiology to prevent photorespiration.
The C4 are the plants in which carbon fixation and the Calvin cycle takes place in different cells. Carbon is fixed in the mesophyll cells with the help of PEP carboxylase enzyme. It fixes carbon and converts PEP into oxaloacetate. The Calvin cycle takes place in the bundle-sheath cells.
In contrast, CAM (Crassulacean acid metabolism) plants are those in which carbon fixation and Calvin cycle are separated into time. The carbon is fixed during the night as it helps in reducing the loss of water through transpiration.
The Calvin cycle takes place during the day time in the same cell, that is, mesophyll cell.
