How might a single base INSERTION into the second codon of the coding sequence of a gene affect the amino acid sequence of a protein encoded by the gene?
A single extra amino acid would be present in the protein.
The amino acid sequence would be altered.
The mutation may have no effect on amino acid sequence.
A single amino acid could change.
All of the above are possible outcomes.

The amino acid sequence would be altered.

Explanation:

Due to the triplet nature of gene expression by codons, insertion of a single base into a gene disrupt the reading frame (known as frameshift mutation), or the grouping of the codons, resulting in a completely different translation from the original.

Thus, the amino acid sequence would be altered

the index of refraction of the second medium is higher. i just took the test trust me !

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
