Answer:
The thyroid gland increase in size.
Explanation:
Iodine plays an important role in the generation of thyroid hormones and is mainly found in the soil in coastal areas and in seawater. In the developing nations, the individuals who live at high elevations or inland are generally deficient in iodine and can develop a condition known as goiters.
In the condition, the thyroid gland increases in size in an attempt to get more iodine. However, in the countries where iodine is added routinely to foods and table salt, the lack of dietary iodine is not the typical reason of goiters.
<span>The best method used to prevent soil depletion would be contour farming.
In contour farming, the land is tiled in consistent elevation. Contour farming is efficient in reducing soil depletion because it can conserve rain water and reduce the erosion of soil.
If there is no contour farming in your option, then choose A. Adding fertilizer. </span>
Answer:
It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.
Explanation:
Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.
The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.
