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: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is : The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test <u>color, malleability, melting points</u>, and to test how shiny or dull it is. I would propose these to increase the <em>certainty</em> in the identity of the metals. Btw, please mark me brainliest.
Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".
The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.
