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.
Answer:
option A " Polymerace chain reaction" (PCR)
Explanation:
polymerace chain reaction is a method in which millions to billions copies of DNA is formed by taking small about of DNA and amplify it for further studies.
It has following three steps:
1- Denaturation : in which un-winding of DNA occur by means of heat at approx 90 degree Celsius for some seconds
2- Annealing: is a step in which DNA priming occur.
3- Extension: complementary nucleotide is added.
