Answer:
do not bind the small ribosomal subunit.
Explanation:
5' CAP is a structure present only in the mRNA molecule. It is characterized as a "helmet" added to the 5' end of the mRNA molecule.
The main function of 5' CAP is to protect mRNA in the cytoplasm (when it leaves the nucleus towards the ribosome). This is because in the cytoplasm can be found the enzymes ribonucleases and fostases that can alter the function of proteins that allow the mRNA to bind to the smaller subunit of the ribosome.
Since tRNA and rRNA do not need to be linked to the ribosome, they do not need the presence of 5' CAP in their compositions.
Answer:
The country's mountainous terrain, many isolated valleys, and numerous offshore islands encouraged the formation of many local centers of power, rather than one all-powerful capital. Another key factor influencing the formation of city-states rather than kingdoms was the Mediterranean.

The innate immune system uses its memory cells to produce more inflammation after the second bee sting resulting in anaphylaxis.
What are anaphylaxis and its effect on immunity?
For the majority of people, a bee sting only causes momentary pain and discomfort, but for those who are allergic to the venom, the results can be disastrous: they go into anaphylactic shock, which includes a drop in blood pressure, itchy hives, and breathing difficulties, and may even result in death if not treated right away. Subjects who are first exposed to a foreign substance, such as a disease or a poisonous chemical like venom, experience innate immune reactions.
Such innate immune responses don't need to be developed into antibodies or be immunized beforehand. As opposed to this, during an adaptive immune response, the immune system produces antibodies that identify the pathogen or toxin that is causing the infection; this process enables the development of vaccines to prevent infectious diseases. In most cases, adaptive immunity is a quicker, more focused, and more potent kind of defense than innate immunity.
So, the correct answer is option D.
