* Vasoconstriction on the vessels near th skin by the sympathetic nervous system to reduce thermal exchanges between the skin and the surrounding environment.
* And increase in heat production:
-by muscular activity:
-by the metabolism:
Answer:
by the nitrocellulose membrane filter method. (more info below)
Explanation:
Genetic relationship between mycoplasma as determined by nucleic acid homology. DNA from each of the mycoplasma isolates tested was reacted separately by complementary RNA synthesized with homologous or heterologous DNA as a primer. The amount of DNA-RNA hybrids formed was tested using the method of the nitrocellulose membrane filter.
hope this helped!
