Answer:
introduces a premature stop codon into the mRNA
Explanation:
A nonsense mutation is a mutation in which an amino acid–specifying codon is changed into a termination codon or stop codon. A stop codon is a codon that does not code for any amino acid and serves to terminate the process of protein synthesis as ribosomes encounter it on the mRNA.
There are three stop codons: UAA, UAG, UGA. A nonsense mutation introduces a stop codon in place of an amino acid encoding codon. It results in the formation of truncated protein which is shorter than the normal protein. Truncated proteins are mostly nonfunctional.
Answer:
it is true. Watersheds can be as small as a footprint or large enough to encompass all the land

Xylem and Phloem. They are both part of the vascular tissue. Xylem is responsible for the movement of water and minerals from the roots to the leaves for photosynthesis. Phloem transports the sugar made during photosynthesis from the leaves to different parts of the plant. I'm pretty sure that water is included when the sugar is transported (in phloem) but you should just check if water is transported after photosynthesis just to make sure
