Answer:
Total 495 liters of natural oil are needed.
Explanation:
It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil.
It means the ratio of natural oil and synthetic oil is
Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.
It means the ratio of natural oil and synthetic oil is
Equate both ratios,

On cross multiplication we get


Divide both sides by 8.


Therefore total 495 liters of natural oil are needed.
Answer: The answer is B- Cool Air Is Sinking
Explanation:
Answer:
B. A proton gradient drives the formation of ATP from ADP and inorganic phosphate via ATP synthase.
Explanation:
Light reaction of photosynthesis includes the splitting of water in the presence of sunlight and electron transfer from PSII to PSI via an electron transport system. During the transfer of electron through cytochrome of the electron transport system, the proton concentration gradient is generated across thylakoids. The proton concentration gradient is harvested to drive ADP phosphorylation by the catalytic site of ATP synthase accompanied by downhill movement protons through its proton channels.
The answers is D because it needs something to survive
Assuming the graph that shows plant groups B and C have a lower growth rate than group A, this shows that every plants needs a certian amount of sunlight to grow. Since they get their energy from the sun, it is the most crucial to a plants survival. If plants dont get the energy they need to live, as producers, primary consumers dont get get energy from producers. If primary consumer cant get energy, neither can secondary consumer and so forth.
