No I have not completed it but, I'd be happy to help you with any other questions you might have.
If atoms share two , three or more pairs of electrons..they are covalent bonds..for example, methane
if the atoms share only a lone pair of electron contributed by only one of the combining atoms but shared by both ..then it is a coordinate bond ..for example, ammonium ion
Answer:
2 valence electrons
Explanation:
All of the elements in group 1 have 1 valence electron, the elements in group 2 have 2 valence electrons, and so on.
Answer:
C
Explanation:
Though the wildlife is based on the weather (you wouldn't see a polar bear in the rainforest), the weather is not based on the wildlife. If you put a polar bear in the rainforest, it won't make it a tundra. The ages of the plants are also completely irrelevant.
Answer: silent mutation: a nucleotide base in a codon is replaced with a different base BUT the resulting amino acid isn’t affected.
Missense mutation: similar to a silent mutation, the only difference is that the switch of the nucleotide DOES result in a DIFFERENT amino acid
Nonsense mutation: a nucleotide base is changed, but that change results in a premature stop of translation
(Remember that after transcription, you are left with a strand of mRNA that Is then translated into a protein. The mRNA is read in increments of three nucleotide bases (A,U,G, or C) which is called a codon. That codon makes a single amino acid, and a strand of amino acids makes a protein)
