Why is vinegar used in food preservation?
weqwewe [10]
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

Q? Describe the concentration gradient of carbon dioxide across the cell membrane.
hoa [83]

Answer:

Carbon dioxide goes with the concentration gradient across the cell membrane. It goes in the direction of the concentration gradient, from high concentration to low concentration.

Explanation:

CO_{2} undergoes simple diffusion, which is an example of passive transport. Passive transport diffusion goes with the concentration gradient, while on the other hand, active transport goes against the concentration gradient.

Going with the concentration gradient means that the molecules move from areas of high concentration to areas of low concentration. This is what carbon dioxide does.

Going against the concentration gradient means that the molecules move from areas of low concentration to areas of high concentration. This goes against the concentration gradient.

Villi

Explanation:

In the small intestine, villi are found present. These villi which appear like a finger-like tissue structure are about 0.5–1.6mm in length in human beings.They have mucosal cells that help in absorption of nutrients. A villus has several microvilli, which increases the surface area of the intestinal wall for faster absorption of nutrients.
