Answer:
The importance of the AUG and UGA bases lies in the fact that the first one is a start codon and the second one is a stop codon, respectively (option a).
Explanation:
Codons or triplets are sequences of three nitrogenous bases, in the mRNA, that determine the synthesis of a specific amino acid.
- <em>AUG </em><em>is called the </em><em>initiation or start codon</em><em>, and is usually at the beginning of a peptide synthesis, in addition to encoding the amino acid methionine.
</em>
- <em>UGA</em><em> is a</em><em> termination or stop codon</em><em> found at the end of a petid chain when it is complete. UAA and UAG codons are also STOP or termination codons and, together with UGA, do not code for amino acids.</em>
The biological importance of start and stop codons is to initiate the synthesis of a protein and to stop the addition of amino acids when their size is adequate.

Typically you use experimental and control groups in an experiment. a control group is like the default, and the experimental is the one you actually experiment with.
for example if i run an experiment on the effects of food dye on a leaf stem, i’ll have my control group (the ones without food dye) to compare to the experimental group (the ones with food dye)
the control group is a way for scientists to see how an experiment truly affected or altered the subject
Answer: the correct option is C(communicate through sign language)
Explanation:
Chantek the orangutan is one of many nonhuman primates that scholars have used to draw conclusions about the origins of human language because they seem to be able to communicate through sign language. Taught by American anthropologists Lyn Miles and Ann Southcombe Channel the orangutan learnt how to communicate using that American sign language.
