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.

Ans.
When a yeast cell enters into meiotic cell division, the resulting daughter cells would contain half of the DNA as present in the parent yeast cell. This is because, meiosis results in formation of four daughter cells from a single parent cell and each cell has half of the amount of genetic material as present in parent cell. During meiosis, if a parent cell has 2n DNA, it would first doubles its DNA content (4n), then divides it equally to four daughter cells and thus, each cell contains half of DNA of parent (n).
Hence, the DNA content will become half when a yeast cell shows meiosis.
