The HeLa cancer call genome is vastly different from Henrietta’s normal genome. A gene transfer from the human papillomavirus 18 virus (HPV18) to human cervical cells created the original HeLa strain of cancer cells.
a) Describe the type of evidence scientists would need to justify this claim.
b) From this discovery, an HPV vaccination was developed. Without HeLa cells, this would not have been possible. Yet, these cells were taken for research without Mrs. Lack’s knowledge. Evaluate the pros and cons of designating biopsy cells as "free cells," cells that can be used without required patient consent.
Answers
Answer:
a. Sequencing the genome and transcriptome of these cells
b. Pros: these cells can be very useful in research (as in Henrieta case)
Contras: 1. patient's family may have inherited the same genetic defect from their common ancestors, thereby this information might be used for malicious people
2. Ethical issues
Explanation:
By using genome sequencing technologies it is possible to determine the nucleotide sequence of the genome (DNA) and their transcriptomic products (i.e., RNAs, especially mRNAs) obtained from a particular cell type. Therefore, these technologies can be used to compare the genome of cancer cells and Henrietta’s normal genome.
HeLa cells have been very useful in pharmaceutical research. These cells have been used in cancer research, in the development of vaccines (e.g., polio vaccine and HPV vaccine), Parkinson's Disease, etc. Moreover, the use of cells without required patient consent may affect the patient’s family by exhibiting information about the genetic conditions of multiple generations of this family, which might be considered unethical and lead to problems associated with the malicious use of this information.
HeLa Cell
It is the first human immortal cell line.
a). The scientist took a tissue sample from a patient named Henrietta Lacks. She was a cervical cancer patient.
Now when the scientist observed the cell sample in the laboratory, they saw that cell was growing indefinitely, i.e. 'immortal'.
So, they named it the HeLa Cell.
Later, the scientist found many copies of HPV-18 (Human Pappiloma Virus-18) in these HeLa cells which is a strain of HPV.
These strains has caused cervical cancer in Henrietta Lacks.
b). The Pros
It could not have claimed if any medical negligence would have occurred.We can overcome the false perception of the patient.The research could be progressed without any interruption from the patient.The Cons
If the consent of the patient was not taken then there would have been legal issues as well as ethical issues.Also, the law orders to stop the research without patient's consent.Without the right patent, the commercialization of the cells would begin.Learn More :

The air bubbles and spongy texture of bread are due to which process?
a. Lactic acid fermentation
b. Glycolysis
c. Alcoholic fermentation
d. The Krebs Cycle
Answers
Answer:alcoholic fermentation
Explanation:
The air bubbles and spongy texture of bread are a result of the process of baking of bread through alcoholic fermentation. Thus, the correct option is C.
What is Fermentation?
During fermentation, carbon dioxide is produced in cell and it is trapped as tiny pockets of air within the dough. The production of carbon dioxide causes the dough to rise.
During the baking of bread, carbon dioxide expands and causes the bread to rise further. In this process, alcohol is produced during fermentation which evaporates during the baking process of bread. In this process, yeast eats the sugar and releases carbon dioxide which causes air bubbles.
Therefore, the correct option is C.

Deforestation is the process of cutting down trees by man, which eventually lead to the the sparseness of trees in otherwise forested areas. The reasons for cutting trees by man may include: habitation by man, clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing as well as mining of minerals.
Deforestation leads to many adverse effects on both man and his environment. These adverse effects include:
Loss of biodiversity in the forests which may lead to extinction of species.; when forest areas are cleared, plants and animals who live in these forests lose their homes and some may eventually die off due to inability to survive in other habitats
Increase in temperature of the earth: Trees serves to cool the earth by removing some gases which cause heating of the earth from the earth. Such gases include carbon dioxide. When these tree are removed, these gases accumulate in the atmosphere leading to increase in earth's temperature.
Also, since tree absorb some gases while releasing others into the atmosphere, when these trees are cut, there would be an imbalance of these atmospheric gases.

how are the lysosomes and vacuole in the cell similar to our excretory system?
Answers
Explanation:
Vesicles and vacuoles are membrane-bound sacs that function in storage and transport. Vacuoles are somewhat larger than vesicles, and the membrane of a vacuole does not fuse with the membranes of other cellular components. Vesicles can fuse with other membranes within the cell system. Additionally, enzymes within plant vacuoles can break down macromolecules.

Lysosomes, Vesicles and vacuoles are membrane-bound sacs that provide storage and transport functions.
What is lysosomes?Lysosomes are defined as membrane-enclosed organelles containing a variety of enzymes capable of degrading all sorts of biological polymers, including proteins, nucleic acids, carbohydrates, and lipids.
It can also be defined as sphere-shaped vesicles or sacs containing hydrolytic enzymes capable of breaking down nearly all types of biomolecules.
Vacuoles are defined as a cell compartment that is devoid of cytoplasm, bordered with a membrane, and filled with fluid.
They are also defined as a membrane-bound organelle found in plant and fungal cells, as well as some protist, animal, and bacterial cells.
Vacuoles are slightly larger than vesicles, and their membranes do not merge with those of other cellular components.
Vesicles can join together with different membranes in the cell system. Enzymes found in plant vacuoles can also degrade macromolecules.
Thus, lysosomes, Vesicles and vacuoles are membrane-bound sacs that provide storage and transport functions.
