The valinomycin treatment caused a decrease in the activity of the mitochondria.
Explanation:
When valinomycin treatment was given, the rate of ATP production is reduced in the cells treated. Since mitochondria are involved in ATP synthesis, it clearly shows that valinomycin inhibits mitochondrial action.
Valinomycin being a selective K+ ionophore, it can transfer potassium ions through selective lipid membranes. This can cause potassium effux in organelles like mitochondria leading to marked loss of potential of mitochondrial membrane and apoptosis in cells.
The effux of K+ ions forms a complex with valinomycin and slows down the mitochondrial part of ATP synthesis by reducing the proton-motive force, but does not block any oxygen electron transfer

Answer:
Arousal theory
Explanation:
Arousal theory is a theory of motivation and according to this theory people are motivated to perform actions because they want to maintain an optimum level of physiological arousal. There is a unique arousal level for each person. When the arousal level drops below this level, the person seeks for some sort of stimulation in order to elevate it up to the optimum level.
The same is the case of Juan in the question. Sky diving gives him a unique level of arousal and for maintaining it he practices the diving even he is tired after a long day of work.
Answer:
Well it depends on the article you’re getting this from but some say it was a meteor and some say it was an earthquake
Explanation:
In plant cells we can see cell wall and also plant cell organelles are membrane bounded beacuse they are eukaryotics .
so answer is plants.
