Answer:
functional groups
Explanation:
Functional groups are molecules with specific atoms and have their own chemical properties when attached to some other substances. Glucose is a simple sugar and has an aldehyde group (CHO) as its functional group. The presence of CHO in it makes it be present in food without any harmful impacts. On the other hand, hexanoic acid has COOH (carboxylic group) as its functional group. COOH group has a tendency to donate its protons and become ionized. It is toxic as it is reactive and tends to affect the pH of the food or solution in which it is present.
Answer:
Natural selection and selective breeding can both cause changes in animals and plants.the difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. for this reason selective breeding is sometimes called artificial selection.

A transference RNA (tRNA) is an adapter molecule that decodes a codon messenger RNA (mRNA) during the synthesis of a polypeptide chain. These molecules (tRNAs) play a fundamental role during translation.
- If a tRNA had an AGC anticodon it could attach a codon having the sequence UCG.
- During translation, tRNAs act at specific sites in a ribosome to synthesize a polypeptide chain (i.e., a protein) from an mRNA sequence.
- The anticodon of the tRNA binds by base complementary to a triplet of nucleotides or 'codon' in the messenger RNA (mRNA) during protein synthesis (i.e., translation).
- According to the base complementarity rules, in RNA, Adenine always pairs with Uracile (Thymine in DNA), whereas Guanine always pairs with Cytosine.
