Witam,
Bardzo proszę o sprawdzenie i ewentualne poprawki mojego streszczenia do pracy licencjackiej, czy jest w miarę zrozumiała i poprawna gramatycznie.
Z góry będę bardzo wdzięczna za jakąkolwiek pomoc.
Ectotherms leave in the areas where the ambient temperature falls below freezing, thus they had to adapt physiologically as well as biochemically in order to survive during adverse conditions.These animals are characterized by their resistance to freezing and they have different strategies i.a. (among other things) avoiding freezing or the toleration on freezing. The avoidance of freezing is associated with supercooling of the organism and not letting the ice crystals to growth inside the body. The tolerance on freezing allows to crystalize within a body and survive by means of the cryoprotective substances which they produce.These substances fulfill the protective function and they can be qualified as alcohols (for the insects it is very often glycerol), carbohydrates (for instance glucose for amphibias) and also specifically synthesized proteins which occur in arctic fishes that are using supercooling. In laboratories there are made an attempts to synthesized the artificial substances so that they will resemble the natural cryoprotective substances and their mechanism of operation which is protecting the cells and tissues from freezing. They have a wide usage in different domains and they play a major role in storage of blood cells or sperm cells, moreover in the medicine they assist in treatment of certain diseases.
