Answer:
The correct answer is B) Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane.
Explanation:
The transcription process in eukaryotes takes place in the nucleus of the cell and after transcription post-transcriptional modification also takes place in the nucleus which is necessary to guide the mRNA out of the nucleus.
First, the process of transcription takes place in which DNA is transcribed to mRNA by an enzyme called RNA polymerase. After transcription post-transcriptional modifications takes place in the given order.
1. Capping: In capping process 7-methylguanosine is added by capping enzyme at 5' end of mRNA.
2. Polyadenylation: In polyadenylation, many poly-A residues are added at the 3' end of the mRNA called the poly-A tail.
3. Intron splicing: Introns are the non-coding sequence present in mRNA which are spliced out of mRNA and all exons are joined together.
After these post-transcriptional process, the mature mRNA is transported out of the nucleus through the nuclear membrane.

Between usage with various meals, food service personnel should clean and sterilize surfaces, tools, and utensils, especially after handling raw meat. Foods that are ready to consume should be kept in the refrigerator's highest shelves. This will prevent the juice from raw foods from dripping down and contaminating the prepared food.
<h3>How may pathogens be kept out of food?</h3>
- Wash hands and other surfaces often.
- Before and after handling food, going to the bathroom, changing diapers, or touching pets, wash your hands with soap and hot water.
- To clean up spills or kitchen surfaces, use paper towels or clean cloths along with hot, soapy water.
<h3>How do food workers guard against viruses on their hands contaminating food?</h3>
The gloves that food workers wear could be infected with harmful infections if they don't properly put them on or don't wash their hands before putting them on. Every time an employee dons a fresh set of gloves, they must wash their hands first.
<h3>How can employees prevent food from becoming contaminated after it has been cooked?</h3>
To make sure food is safe to eat, use a food thermometer, keep food hot after cooking (140°F), and microwave food thoroughly (165°F). Refrigerate right away because if perishable goods aren't chilled, bacteria that cause disease can grow in them in just two hours.

Answer:
Both earthquake and volcanoes are concentrated in specific regions.
Explanation:
The distribution of earthquake on earth is concentrated in specific zones where the plate tectonic meets or fuse with each other. Volcanoes are also concentrated in specific regions on the earth. Most volcanoes are concentrated on the edges of continents, on island chains, or long mountain ranges beneath the sea. There is a great relationship between earthquake and volcanoes because volcanic eruptions is the cause of earthquake in a region.
