Depending on the organism the number of chromosomes in a cell may change.
Different organisms have a different number of chromosomes, for example we have 46 and a fruit-fly(drosophila melanogaster) has 8.

Answer:
3. The ETC cannot establish a proton gradient to drive chemiosmotic production of ATP
Explanation:
Reduction of FAD+ and NAD+ during glycolysis and Kreb's cycle produces FADH2 and NADH respectively which in turn give their electrons to the molecular oxygen via electron transport chain (ETC). This electron transfer is accompanied by the pumping of protons towards the inter-membrane space resulting in the generation of an electrochemical gradient.
The energy of the electrochemical gradient is harnessed to drive ATP synthesis. The process is called chemiosmotic ATP synthesis. The mentioned insecticide would not allow the FADH2 and NADH to reduce oxygen and no electrochemical gradient is developed to drive the chemiosmotic production of ATP.
A theory is an explanation that ties together many hypothesis.
- A well considered explanation for observations of the natural world that has been developed through the scientific method and that combines numerous facts and hypotheses is known as a theory.
- A scientific hypothesis offers a suggested resolution based on data, as opposed to an educated assumption.
- A thorough explanation of a significant aspect of nature that is supported by data acquired through time is referred to be a theory. Predictions concerning occurrences that have not yet been observed can also be made by scientists using theories. A scientific theory is a well-supported explanation of a particular phenomenon in the natural world that is based on a body of facts that have been repeatedly verified via observation and investigation.
- In that they are guiding principles that can be utilized to forecast behavior, scientific laws are comparable to scientific hypotheses.
Therefore, theory is the correct answer.
