Answer and Explanation
The normal microbiota that harbouring an R plasmid will transmit its R plasmid to the normal microbiota because the normal microbiota does not have R plasmid after transmission of R plasmid its increases the resistance capacity of normal microbiota. This is the significance of normal microbiota that harbours an R PLASMID.
Answer:
B) Na+
Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a <em>phospholipid bilayer</em> made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while the polar ends faces towards all the molecules inside and outside the cell.
Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.
Since this is movement that is occurring against the natural movement from high to low concentration, this is Active transport.
The option C.
D. because if you think about the dna is the same as thier genetic material/genes whatever you want to call it.

components used to make or repair jewelry are called jewelry findings. Jewelry findings are basically
components, materials and elements such as clasps, pins, hooks, tabs etc that
can be used in making, assembling or repair a piece of jewelry.
