Option c. freeze-drying technology dehydrates foods through sublimation
Sublimation is one of the example, in freezing, it needs to cool it down first. If there is some water in some food, this water becomes ice. Then take away the air around that you want to freeze-dry, this reduces the pressure a lot. The boiling point of water drops when you reduce pressure, so when you drastically reduce pressure to almost zero it eventually drops below the temperature of the frozen food. This effectively makes the solid ice in the food "boil" or sublimate, it becomes a gas without first becoming a liquid.
We could describe this process using a picture of water-molecules as particles so you could for example first draw water molecules in a crystal structure with air particles above it which keeps the water particle in a crystal. Then you could draw another picture with no air particles and some water particles escaping the crystals in all directions like a gas like sublimation.
Well here's an image of the things that do occur (different phases). You can see which ones are are right in the answer choices and pick out the wrong one. I hope this helps...
Answer:
Stem cells are simple, unspecialised cells found in animals and plants that have the ability to divide to form cells of the same type. They can also differentiate into a variety of specialised cells. Stem cells can be harvested from embryonic umbilical cord or adult bone marrow.
Unlike New World monkeys, hominines D. Have opposable thumbs
Opposable thumbs refers to the structure of thumbs that allow the thumb to move around more freely and able to touch all other fingers.
The hominines had these type of thumbs which help them had the ability to clib trees faster in order to survive in their environment
