If NOCTURNAL ACTIVITY is one of the choices, that's your answer.
Answer: c. are spliced out of the message.
Explanation: Intron are non-coding portion of the DNA sequence. They do not code for any specific amino acid and are spliced or removed before splicing.
Exons are DNA sequence that code for specific amino acid they are usually left after introns are removed and are joined together before translation into amino acid sequence. Intron splicing can lead to splicing some exons which can lead to formation of an entirely new amino acid or protein.
Spliceosome are enzymes for splicing introns.
Answer and explanation:
Monophyletic species are the species whose lineage belongs to the common recent phylogenetic ancestor. As mentioned in the question, the girl has 3 species namely G, H, and K. Because there is no other criteria given, we assume that the closeness of alphabets would reflect the closeness of species. Thus, G and H are closer relative than K. Therefore, if she adds <u>I, and J species</u> in the list, all of them will be closer relatives and we can say that they are monophyletic now.
Lead.
"Due to insufficient water treatment, lead leached from water pipes into the drinking water, exposing over 100,000 residents to elevated lead levels."
