Regarding this, how does repeated freeze/thaw process cause damage?
Physical weathering is caused by the effects ofchanging temperature on rocks, causing the rock to breakapart. Freeze-thaw occurs when water continuallyseeps into cracks, freezes and expands, eventually breakingthe rock apart.
Furthermore, how does freezing affect bacteria? Freezing foods renders bacteria inactivebut doesn't actually kill anything. That means if your foodwent into the freezer contaminated, once thawed it will stillharbor the same harmful bacteria. Cooking it to therecommended temperature is the only way to ensure that your food issafe.
In this way, what is meant by freezing and thawing?
Definition: Freeze-thaw weatheringis a process of erosion that happens in cold areas where ice forms.A crack in a rock can fill with water which then freezes asthe temperature drops. As the ice expands, it pushes the crackapart, making it larger.
Does freezing damage DNA?
There is some controversy regarding DNA damageresulting from repeated cycles of freeze-thawing and it iscommon practice to store DNA in aliquots to minimise thenumber of times the DNA is thawed. Interestingly, a study byBethesda Research Laboratories11 found no evidence thatfreeze-thawing cycles causes DNA damage.
