Answer:
18 ATP.
Explanation:
Total 18 ATP are produced because 9 FADH2 are converted into 9 ATP molecules and the earlier 9 ATP molecules are already present in the first b-oxidation process. The first Krebs cycle produces 27 NADH, 9 FADH2 and 9 ATP while on the other hand, the second Krebs cycle produces 9 ATP molecules from 9 FADH2 so total it produces 18 ATP molecules.

The Scientific Method > Scientific Method Steps<span>Scientific Method StepsThe ‘scientific method’ merely refers to a broad framework for studying and learning more about the world around us in a scientific manner. It is not so much a series of absolute, unchangeable steps as a guideline to the method that must be used when trying to reach a scientifically acceptable theory about a subject matter. Therefore, it is not possible to provide a finite number of steps or an exact procedure for following the scientific method. However, the scientific method steps detailed below describe the main steps that scientists commonly take when conducting a scientific inquiry.Steps of the Scientific Method<span><span>Make an ObservationScientists are naturally curious about the world. While many people may pass by a curious phenomenon without sparing much thought for it, a scientific mind will take note of it as something worth further thought and investigation.</span><span>Form a QuestionAfter making an interesting observation, a scientific mind itches to find out more about it. This is in fact a natural phenomenon. If you have ever wondered why or how something occurs, you have been listening to the scientist in you. In the scientific method, a question converts general wonder and interest to a channelled line of thinking and inquiry.</span><span>Form a HypothesisA hypothesis is an informed guess as to the possible answer of the question. The hypothesis may be formed as soon as the question is posed, or it may require a great deal of background research and inquiry. The purpose of the hypothesis is not to arrive at the perfect answer to the question but to provide a direction to further scientific investigation.</span><span>Conduct an ExperimentOnce a hypothesis has been formed, it must be tested. This is done by conducting a carefully designed and controlled experiment. The experiment is one of the most important steps in the scientific method, as it is used to prove a hypothesis right or wrong, and to formulate scientific theories. In order to be accepted as scientific proof for a theory, an experiment must meet certain conditions – it must be controlled, i.e. it must test a single variable by keeping all other variables under control. The experiment must also be reproducible so that it can be tested for errors.</span><span>Analyse the Data and Draw a ConclusionAs the experiment is conducted, it is important to note down the results. In any experiment, it is necessary to conduct several trials to ensure that the results are constant. The experimenter then analyses all the data and uses it to draw a conclusion regarding the strength of the hypothesis. If the data proves the hypothesis correct, the original question is answered. On the other hand, if the data disproves the hypothesis, the scientific inquiry continues by doing research to form a new hypothesis and then conducting an experiment to test it. This process goes on until a hypothesis can be proven correct by a scientific experiment.</span></span></span>
A/Cell membranes and cell walls are selectively permeable and aid in communication.
Explanation:
Cell Membranes or cell wall have phospholipid bi layer which functions
as a selectively permeable barrier that separates an internal
environment from an external one. They are selective permeable through
passive process (concentration gradient) allowing certain molecule
diffuse into cells
Fossil fuels are definitely non renewable (such as coal and gas) because they cannot immediately be replenished.
Elements such as wind and water are renewable because they're natural and are regularly produced
