Vinegar is an extremely acidic liquid. Very few microorganisms (ie bacteria and fungus which cause foods to spoil) can survive in such an acidic environment. Among other effects, it can destroy their cell walls, and prevent their own enzymes working (enzymes are extremely pH sensitive). There are a small number of microorgamisms which are adapted to survive in extreme acidity. However, this adaptation prevents them from surviving in more 'normal' environments. Therefore, anything which can survive in the vinegar, will not likely survive on your kitchen surface, and the same is true the other way around. Therefore, as vitually nothing can colonise whatever is in the vinegar, the food will be very effectively preserved. . . . . . . . . . . you can say........................ . . the low pH a nd high acidity of vinegar destroy bacteria
Answer:
Actually, D is the correct answer
Answer
D
Glycolysis is the process, which occurs in cytoplasm of cell. This is the process which involves the breakdown of glucose to pyruvate. Citric acid cycle and beta oxidation of fatty acids occurs in the mitochondrial matrix, electron transport chain and oxidative phosphorylation occurs in the oxysomes. So, it is NOT a.
It has to be 2 and 3, which is D.
Explanation:
The correct answer is: marsupials.
Marsupials are actually defined by their ability to hold the young in the pouches, where they can be well protected. Some examples are Kangaroos and Koalas.
Other answers are wrong: for example, gymnosperms are plants, not animals.
