Answer:
Answer is explained below.
Explanation:
A. The observed single stranded regions are found in the mRNA.
B. The loops represent introns (Non-coding portions of the mRNAin primary transcript ). The intron sequences are removed to form a mature mRNA by splicing.
C. If the scientist use RNA and DNA from bacteria, loops cannot be seen. Because introns are produced in only eukaryotes but not in prokaryotes.
<h2>Cell Analogy</h2>
Explanation:
As we see that parents control everything in the house. Similarly,the nucleus controls everything in the cell.
A door is analogous to the cell membrane because it allows people come and go. Similarly,the cell membrane in a cell can allow certain things to enter and exit.
The cytoplasm fills the space in a cell. It is similar to air which is filled everywhere in the house.
- Nuclear membrane: Security guard
The nucleus in a cell is protected by nuclear membrane. The nuclear membrane is analogous to secuity guard. As people in a house are protected by security guard, similarly nucleus is protected by nuclear membrane.
- Endoplasmic reticulum: Hall ways
Endoplasmic reticulum transport things to other places in the cell. It is similar to hallways which help us to reach different places in the house.
The golgi bodies modify,sort and package proteins.
It send them to other parts of the cell when needed.
It is similar to a Car which transports people and can store stuffs.
The mitochondria in a house is analogous to Stove as it breaks down nutrients and turns them into energy. Similarly, the Stove in our house, cooks foods and it is converted into energy when consumed.
The ribosomes are a cell structure that make protein. It is same as a kitchen in our house where people make food or proteins.

In FILTRATION, some type of pressure, such as gravity or blood pressure, forces substances across a membrane that acts like a filter.
Filtration
<span>Urea is the cellular waste product that the kidneys remove from the blood.Kidneys are the two bean shaped organs that has several functions to keep the body healthy. It not only removes urea from the blood, but also helps in the formation of urine and maintaining the fluid level of the body. The two kidneys are placed on the two sides of the spinal cord. The blood enters the kidney through the renal artery. The nephron within the kidneys mainly take out the waste products and the excess water from the blood and purifies it.If the kidneys of a person fail to work properly then it becomes important to perform dialysis for taking out the waste materials from the blood.</span>
