Answer:
I would think it would be B Hope this helps out.
Explanation:
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.

I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
Answer:
2) is chemically specific
Explanation:
Enzymes are organic catalysts which speed up or control chemical reactions in cells. Enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction or a group of closely related reaction. Enzyme salivary amylase found in the mouth only hydrolyses starch into maltose.

In human's tounge papilae is the organ that make us able to taste everything that we put in our mouth. It consist of five different regions, and each separate regions are capable to give response for 5 unique taste: sweet, sour, bitter, salty, and umami</span>
