Because it's partially permeable membrane so it won't let anything get inside the leaf so by this cuticle the leaf is protected not to let any foreign substances in and preventing loss of water
Phosphate groups of the nucleotides in the diagram are marked with W.
Option C.
<h3><u>Explanation:</u></h3>
DNA is a macro molecule which is formed of polymerization of deoxyribonucleotides. Four types of deoxyribonucleotides are present which are adenosine, guanosine, thymidine and cytosine triphosphate. These nucleotides are polymerized based on the genetic setup.
The phosphate groups attached with the sugar molecule are actually polymerized with the o glycosidic bond. That's marked with the letter W. These phosphate molecules are attached with the sugar molecules which actually are attached with the nitrogen bases. They in total forms a nucleotide, hence the whole DNA. X in the diagram are nitrogen bases and the Y are the hydrogen bonds between the complementary nitrogen bases
Color blindness is X linked trait and is carried on X chromosome so when a <span> A mother with normal color vision and a color blind father have a color blind daughter the offspring will be
</span><span>. Some of their sons can have normal color vision
</span>because male is XY and female XX
so i conclude option B is correct<span />
Lithosphere is the final layer on the planet Earth, erosion caused by wind (atmosphere) or rain (hydrosphere) may also wear down rocks in the lithosphere.
