Answer:
1. No, tissue must not be removed without the patient's consent. Especially if it's for research purposes however fetal blood test or a biopsy.
2. It was cultured by the roller tube technique. In which the cells are lined/immobilized to the walls of the tube by serum or another medium and rotated(as in water bath) for adequate and uniform aeration.
3. The human papillomavirus 18 (HPV-18) that was later found to cause the strain of the cervical cancer she had. These viruses have two proteins E6 and E7 that turn off some of the tumor suppressors like pb53 and Rb and cause the cell lining to grow too much and cause changes in the cells that may bring cancer in some cases.
4. No. She received the standard treatment of the cervical cancer at that time, being stiched invasively with radium pouches, since the hospital was one of the few that treated black people.
5. Personally, both are important. But clearly for the betterment of the human race and people yet unborn, the medical knowledge that'll be obtained from stufying the cells and their overall benefits is more important. I completely disagree with the way the HeLa cells were obtained for I believe consent is a must since the tissues were hers to begin with and not the hospital's property. It's crucial for the patient to be notified of the pros and cons of giving the tissues and if manners of compensations can be discussed. Although malicious intents aren't wide but they're still there and it can be seen as invasion of personal privacy to some patients as well as relatives of the deceased.
6. Compensation to the Lacks family must be on the Lacks family terms. Because obviously all the discoveries made were due to the research done by the hospital still the tissues were taken without consent therefore if the Lacks family want to be compensated they must be as they want. Obviously, family can't be paid for and no amount of money that the institutions will deem fit would ever be enough unless the family decides on the amount themselves.
7. No. If the patient is alive credit must be given to the patient and the patient clearly informed on the patenting licenses and rights. And if the patient is dead then the family must be notified as well on the patenting licenses and rights. And the patenting decisions must be made only after the approval has been given by the owner of the tissues or the next of kin.
8. > Invasion of privacy was raised especially on Henrietta as well as her family.
> Ownership rights especially on th institutions that sold and benefited from the cells as well as the research and articles published without the family's knowledge.
> Right on one's body was raised on the legalization behind tissues, genes, body fluids. Things that weren't on the table for discussion are now put on the light.
This is what I think. All the best.

What would happen if a similar diffusion/osmosis experiment were performed with plant cells instead of animal cells? would plant cells behave in the same manner?
Answer: because plant and animal cells can tolerate different concentrations of water.
Explanation:
Image result for What would happen if a similar diffusion/osmosis experiment were performed with plant cells instead of animal cells? would plant cells behave in the same manner?
Osmosis affects plant and animal cells differently because plant and animal cells can tolerate different concentrations of water. ... However, plant cells need more water than animal cells, and will not burst in a hypotonic solution due to their thick cell walls; hypotonic solutions are ideal for plant cells.
When diffusion and osmosis experiments are performed on a plant cell, the plant cell will expand because it has a rigid cell wall, which prevents it from bursting.
What are osmosis and diffusion?Osmosis is the process when molecules move from a lower concentration area to a higher concentration area.
Diffusion is the process, in which the molecules move from higher concentration to lower concentration.
When osmosis happens to the animal cells, it will fully fill and burst.
But, it will not happen in the plant cell, because it contains a cell wall.
Thus, When diffusion and osmosis experiments are performed on a plant cell, the plant cell will expand because it has a rigid cell wall, which prevents it from bursting.

Answer:
Einsteins Theory of Relativity can be
supported with evidence of light doing
what around the sun?
In 1919 observation of a solar eclipse confirmed Einstein's prediction that light is bent in the presence of mass. This experimental support for his general theory of relativity garnered him instant worldwide acclaim. ... This has been measured directly and also through the gravitational redshift of light.
Answer:
The Earth moves around the Sun, due to the Sun's gravity. ... According to Newton's theory, the Earth should know immediately that the Sun had disappeared. But Einstein said that couldn't be right. Because, according to him, nothing can travel faster than the speed of light — not even the effects of gravity.
Explanation:
•Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same•for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired.
•Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends

Why are different types of cancers named based on where in the body they originate (breast cancer, skin cancer, bone cancer, etc.)? Why does it matter from which organ or tissue type the cancer developed?
Answer:
Cancer is caused by abnormal cell division. However, a skin cell is different from a bone cell. Because of that, the cancers that can occur behave differently.

A typical eukaryotic cell has enough available ATP to meet its needs for about 30 seconds. What is likely to happen to an individual when they exhaust their ATP supply? ATP will be transported into the cells from the circulatory system. Catabolic processes will be activated to generate additional ATP. The athlete will have to sit down and rest. Anabolic processes will be activated to produce new mitochondria.
In the case of given scenario, the catabolic processes will be activated to generate additional ATP. The correct option is B.
What are catabolic processes?Catabolic processes are the set of enzyme-catalyzed responses that disintegrate or degrade fairly large molecules in living cells.
Part of the chemical energy emitted during catabolic processes is conserved as energy-rich compounds such as adenosine triphosphate [ATP].

Por qué el melanismo industrial es un tipo de selección direccional
El melanismo industrial es el fenómeno genético por el cual lepidópteros que viven en zonas industriales tienen un color oscuro. Este fenómeno se debe a que la selección natural favorece un determinado genotipo.
La selección natural es el principal mecanismo por el cual las especies y los organismos evolucionan (cambian) para adaptarse a su ambiente.
La selección natural se define como la supervivencia y reproducción diferencial de los individuos mejor adaptados a su ambiente.
Este proceso (selección natural) tiende a modificar las frecuencias de génicas (alélicas) y genotípicas las cuales determinan los rasgos adaptativos a lo largo de las generaciones.
La selección direccional es un tipo de selección natural que tiende a favorecer a un sólo alelo a lo largo del tiempo.
En el melanismo industrial, los lepidópteros (polillas) que expresan el alelo que codifica para el rasgo fenotípico 'color oscuro' se ven favorecidos porque esta característica les permite mimetizarse en un entrono ambiental oscuro causado por la polución ambiental de zonas industriales.
