The most important property of the cell membrane is its selective permeability: some substances can pass through it freely, but others cannot. Small and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.

Selective permanently, is the reason why the cell membrane only let's certain things pass through. small noon polar molecules (oxygen & carbon dioxide) pass through by simply diffusing. But other molecules use other types of passive transport or active transport.

Daniel [21]

Given what we know, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours.

TCS food refers to food that must be stored in temperature-controlled environments to ensure safety.
These foods, if not stored properly and at the correct temperatures can cause sickness to the consumers.

<h3>Why does it need to be date-marked?</h3>

The reason the foods need to be date-marked is to relay information to the potential consumer as to by when the food should be consumed.
This is done to ensure that if stored correctly, the food does not have time to spoil and cause health risks for consumers.

Therefore, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours in order to protect the health of the consumers.

ivolga24 [154]

When ingesting a substance, it had its own unique effect on our body, for better or worse. For example, take a greasy food, such as friend fries. It shoots our cholesterol way up, bringing the fat content in our bodies up. Therefore, we truly are what we eat, we eat healthy, we’ll be healthy. We eat unhealthy, we’ll be unhealthy.
