The human activity that creates the least threat to global stability is : Reuse of Plastic bags.
Plastic bag need a lot of time to be degraded in the soil which will create a threat to the environment. Reusing plastic bag will reduce this threat.
hope this helps
yes they are quit different in some things
Answer:
(d) Cell wall
Explanation:
The cell wall is a structure located on the outside of the cell membrane in the cells of plants, bacteria, fungi, and algae. It is a resistant, tough and flexible layer, which has the vital function of supporting the osmotic pressure inside the cell, preventing the cell from lysis when water enters. Besides, it has the function of giving rigidity, support and defining the shape of the cell.
In molecular biology, restriction fragment length polymorphism, orRFLP, is a technique that exploits variations in homologous DNA sequences. It refers to a differencebetween samples of homologous DNAmolecules from differing locations ofrestriction enzyme sites, and to a related laboratory technique by which these segments can be illustrated. InRFLP analysis, the DNA sample is broken into pieces and (digested) byrestriction enzymes and the resultingrestriction fragments are separated according to their lengths by gel electrophoresis. Although now largely obsolete due to the rise of inexpensive DNA sequencing technologies, RFLP analysis was the first DNA profilingtechnique inexpensive enough to see widespread application. RFLP analysis was an important tool in genome mapping, localization of genes forgenetic disorders, determination of riskfor disease, and paternity testing.

1) The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure. The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene DNA encoding it.
