B.The molecules of one substance break down in the other.
C.Different samples of a single mixture have different characteristics.
D.One substance can be separated from another through physical means.
Answer: The correct answer is D) One substance can be separated from another through physical means.
Mixture is a combination of two or more substances that are combined or mixed physically in a way that they do not loose their identity.
This means that mixture does not undergo any chemical change and it can be separated through physical means (like filtration). It can be of solid, liquid, or gaseous molecules.
Mixture can be primarily divided into homogenous ( having uniform composition that is every sample will have same property) and heterogenous mixture ( non uniform composition that is not every sample will have same property).
Thus, option D) is a property of every mixture.
- carbon dioxide
- water
- energy
Marinades containing vinegar, wine, or yogurt can tenderizemeat due to their acidity. The acidity breaks down collagen, a tough protein, making the meat more tender.
Marinades that contain vinegar, wine, or yogurt are able to tenderize meat by breaking down collagen into smaller polypeptides because of their acidity.
These ingredients are acidic in nature, and this acidity helps to break the bonds in protein strands, making them more tender.
Specifically, the acid in these marinades works to break down the collagen in the meat, a tough protein that can make meat difficult to chew.
By breaking down the collagen, the marinade makes the meat more tender and easier to eat.
