I think you might've forgotten something. There is no labels, pictures, or any options. Add some more stuff and I'd be able to help out.
Answer:
Rough endoplasmic reticulum differ from smooth endoplasmic reticulum by the presence and absence of ribosomes in their surface.
Explanation:
Rough endoplasmic is named so because RER contain ribosomes at their surface and due to the presence of ribosomes rough endoplasmic reticulum play an importnt role in protein synthesis or translation.
Whereas smooth endoplasmic reticulum does not contain any ribosome in its surface.smooth endoplasmic reticulum helps in the biosynthesis of lipid and steroids along with detoxification of toxic compounds.
Answer:
The structure of the DNA is ideal for the complex function that it plays.
Some of the features of the structure of all DNA molecules are:
<em>Sugar- phosphate backbone:</em>
The sugar- phosphate backbone is ideal for providing the DNA a ladder- like shape which is essential for its functions.
<em>Hydrogen bonds:</em>
The hydrogen bonds present in the nucleotides keep both the DNA strands intact. If the hydrogen bonds were not present then the double helix would not have been able to form.
<em>Coiling:</em>
The structure of the DNA is coiled and super coiled so that it can fit into an organism.

I believe this as the mother passes antibodies to the child through the last three months of pregnancy, and this is a passive immunity </span>
The terminal cisternae releases calcium ion
The terminal cisternae act as calcium storage sites. The calcium ions stored in the terminal cisternae are essential in muscle contraction. The calcium release unit of muscle consists of terminal cisternae of the sarcoplasmic reticulum and it is adjacent transverse or T- tubule that is the invaginated part of the surface membrane.
