What do you need help with hun
Answer;
-Noble gases or Group 18 elements
Explanation;
A full valence shell is the most stable electron configuration. Group 18 elements or noble gases such as helium, neon, and argon, have a full outer, or valence, shell. Elements in other groups have partially-filled valence shells and gain or lose electrons to achieve a stable electron configuration.
They are extremely unreactive and do not form bonds with themselves. Solid helium is the the ultimate fine powder being monotomic.
Answer:
Explanation:
The non-coding DNA sequences forms the part of the organism's DNA. It is the part of the human genome which does not encode for any protein sequence. Some of the non-coding DNA may be transcribed into into any of the functional non-coding RNA molecules such as ribosomal RNA, transfer RNA and regulatory RNA. Other functions of the non-coding DNA involve translational and transcriptional regulation of the protein coding sequences, origin of DNA replication process, scaffold attachment, telomeres and centromeres.
Both of them produce mucus.
there are two main types of explosive events in the Sun: solar flares and coronal mass ejections. Impulsive energy release in solar flares is one of the most dynamic and highly energetic phenomena in the Solar System
