Os alienígenas da franquia Alien possuem células como as conhecemos?
Eu quero saber como eu assumi que eles não e apenas secretavam um sistema exosquelético resinoso .

The chestburster then matures to an adult phase, shedding its skin and replacing its cells with polarized silicon.
Due to Horizontal gene transfer during the gestation period, the Alien also takes on some of the basic physical attributes of the host from which it was born, allowing the individual alien to adapt to the host's environment.
Ambos os fatos implicam que as células estão envolvidas.
De acordo com Ash no primeiro filme Alien, o alienígena do facehugger realmente tem uma estrutura celular. Quando danificadas, as células são substituídas / reparadas por " silício polarizado " o que implica strongmente que as células originais são feitas de algo diferente de silício .
Ash: But I have confirmed that he's got an outer layer of protein polysaccharides. He has a funny habit of shedding his cells and replacing them with polarized silicon, which gives him a prolonged resistance to adverse environmental conditions.
Não há indicação de que os Xenomorphs adultos são feitos, mas os cientistas do Aliens, Manual Técnico dos Colonial Marines < Suponho que eles sejam realmente uma forma de vida baseada em flúor , em vez de baseada em silício . Isso também explicaria o extremamente strong ácido molecular para o sangue, já que a acidez quebraria qualquer material que o alienígena ingere, incluindo materiais orgânicos e certos compostos inorgânicos, como vidro e certos metais.
"It would work as a hydrofluoric/hydrochloric mix. The preferred concentration in the blood is KF. However, an embryo implanted in a human body would have access to a ready supply of HC1 from the host's stomach. It starts life with an HCl imbalance which could alter as it grows. Of course, it could take on additional chlorine and fluorine from its prey, or it could 'salt' it with sodium chloride or sodium fluoride."
"Sorry, this modal is just too elaborate for my tastes. I still don't buy it. Even with PTTE [Teflon] coated cell-membranes, wouldn't the body chemistry of a fluorine-based embryo be so hostile that it would just eat through the linings of the host's body?"
