My little brother’s science teacher gave him a mini project. The guiding question is “What brand of paper towels is best?” Basic

ally, there are barely any rules whatsoever. You can do anything you want to justify your claim. So far, he thinks that he could measure absorbency or something. However, this isn’t set in stone What experiments can he conduct? What should his research question that is answered by the experiments be? What can he measure? For some context, the person who does the best work out of the grade gets a free A+ on an upcoming test. In conclusion, what can he do to conduct a successful experiment, sound smart, and possibly get that free A+?

Answer:

Absorbancy is a good way to measure the products .To answer your first question Id first go out and buy two different brand of paper towels ( id do the walmart brand and the competing brand for a simpler outcome) . Then put two puddles of water on a flat surface.  After that id lay one paper towel of each product on each puddle measuring which puddle absorbs faster into the paper towel  thus, measuring its absorbency . for his  research question he should ask

Answer is : C, increase the surface to allow more space for ATP synthesis.

As it produces large amounts of ATP through oxidative metabolism of pyruvates, which are produced by glycolysis. The main job of mitochondria is to perform cellular respiration.  This means it takes in nutrients from the cell, breaks it down, and turns it into energy.  This energy is then in turn used by the cell to carry out various functions. Each cell contains a different number of mitochondria The number present is dependent upon how much energy the cell requires.  The more energy a cell needs the more mitochondria that will be present. Cells have the ability to produce more mitochondria as needed.  They also can combine mitochondria to make larger ones. The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP),  through respiration, and to regulate cellular metabolism.The central set of reactions involved in ATP production are collectively known  as the citric acid cycle, or the Krebs cycle. However, the mitochondrion has many other functions in addition to the production of ATP.

katrin2010 [14]

Answer:

The correct answer will be option-D.

Explanation:

In the given question doctor used the scientific method to understand and explain the natural phenomenon.

The scientific method involves various steps like making an observation followed by background research, predicting a hypothesis and performing tests to test the hypothesis. These steps have been performed by the doctor.

After these steps the doctor will analyse the result and reach to the conclusion. This would be followed by publishing the results in a scientific journal where it would be reviewed by the fellow scientists.

Therefore, the next step will be publishing the result and thus option-D is the correct answer.
