Researchers wanted to do research because they thought normal cells spontaneously became cancerous cells.
What are Henrietta's cells?The first immortal human cells to be generated in culture were from Henrietta Lacks. They are also known as Henrietta's cells. They were crucial in the creation of the polio vaccine. In the early space flights, they went up to investigate what would happen to cells in weightlessness.
Her cells have since been employed in numerous significant scientific breakthroughs, such as cloning, gene mapping, and in vitro fertilization.
After the rumor spread that Henrietta's cells took over many other cell cultures in research labs scientists wanted to do research, because they thought that normal cells are converting into cancerous cells.

What is one reason scientists are trying to culture meat in laboratories instead of simply hunting or raising animals?
Answer:
Many reasons - but a really good question.
Explanation:
Cruelty - eating meat poses ethical issues to some people. They dont eat meat because they dont believe animals should be harmed. Growing laboratory meat takes away the need for slaughter.
Land used - a big issue with producing meat is the amount of land we need to raise cattle and to grow the food to feed cattle. Rainforest, woodlands, moorland have to be destructed to make way for pasture land for cattle. The food that cattle or animal eats also needs to be grown, which requires more land. Laboratory grown meat doesnt require all the pasture space for raising or feeding animals.
Water use - the amount of water that goes into producing meat is very high when compared to amount of meat that you get back. Water availability is another global issue that may be able to be addressed by lab produced meat.
When animals are reared from meat, they may be killed in unethical ways thereby making it ethically irresponsible to raise animals for meat.
Animals are widely used as food. This food from animals or having animal origin is known as meat. The ethical issues are of key importance in raising meat for food.

Succession describes the sequential appearance and disappearance of species in a community over time after a severe disturbance. In primary succession, newly exposed or newly formed rock is colonized by living organisms; in secondary succession, a part of an ecosystem is disturbed and remnants of the previous community remain especially soil. In both cases, there is a sequential change in species until a more or less permanent community develops. What is the process of ECOLOGICAL SUCCESSION? *
Answer:
The answer will be listed below.
Explanation:
Ecological succession is the process of change in the species structure of an ecological community over time. It is a process by which an ecological community undergoes more or less predictable changes following a disturbance or the initial colonization of a new habitat.
