Answer:
Postharvest physiology plays a fundamental role in extending the shelf-life and quality of plant products. An example of postharvest physiology methodologies is by reducing the temperature to improve shelf-life before consumption
Explanation:
Postharvest physiology refers to the methodologies used for extending shelf-life and quality, thus being a critical issue in food systems. Postharvest approaches include chemical treatments, temperature reduction, cleaning and disinfection methods, etc. Crop varieties are genetically selected in order to maintain nutritional qualities of stored seeds for a long time after harvest. These seeds are also controlled during storage by using postharvest handling practices (e.g., chemical and enzyme inhibitors that extend shelf life).
Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
Answer:B
Explanation:
WHEN WE RESPIRE THE CO2 EXCHANGES TO 02 IN THE ALEVOLI
Answer:
They test or measure something.
Explanation:
Primary research articles report on research that has been completed. Therefore, a primary research article will review and analyze studies, and will state the research question and hypotheses of the studies presented. A primary research article does not test or measure anything, but will report on studies that do.
