Hello!
RNA in cells differs from DNA in that it is single-stranded and can fold up into a variety of structures.
RNA is the abbreviation for RiboNucleic Acid. It is a biological molecule that fulfills an important role by copying the information stored in the DNA (DeoxyriboNucleic Acid) and transporting it to the different proteins by folding into different shapes. Its name come from a Ribose molecule that is present in this single-stranded molecule.
Viruses don't have DNA, only RNA. They only replicate in the host's cells by copying their own RNA information.
Have a nice day!
Answer:
High specific heat capacity.
Explanation:
Thermoregulation is the ability of an organism body to maintain it's internal temperature. It is an important aspect of homeostasis which is ability of an organism to maintain internal temperature not minding the surronding environment.
Blood have high specific heat capacity which help to maintain body temperature. Blood absorbs and distribute heat to the body, so as to maintain homeostasis. Blood vessels contracts when they react with outside environment.
