Answer:
HeLa cells contain rare traits that make them invaluable to scientific research. Research into the Lacks family may provide insight into this mutation and cell proliferation.
Explanation:
HeLa cells have a controversial origin, rooted in ethical breaches. They were derived from a non-consenting, female African-American donor patient, Henrietta Lacks who was terminally ill with a form of cervical cancer. These particular cells have a remarkably short period of proliferation, due to their active telomerase.
During cell division, these telomoerases were found to make repeat copies of the cell's telomere, and the cells can divide an unlimited number of times in lab cell cultures- a very rare occurrence. They were later commercialized- HeLa cells are durable, robust and commonly used in cancer cell research.
Explanation:
To know where erosion and deposition will occur, since we have no visual aid, we need to understand these concepts.
Erosion and deposition are terms that are often used in the geology especially when a rock is being transformed from either metamorphic or igneous to sedimentary rocks.
- Erosion is the removal of lose and weathered rock materials from the surface of the earth.
- Deposition is the laying down of the sediments in a basin.
An igneous and metamorphic rocks can be transformed into a sedimentary rock by erosion and deposition.
Prolonged exposure to the action of agents of denudation degrades a rock and forms sediments from them.
The sediments are removed by erosion.
As they are transported, the come to settle and rest in sedimentary basin.
Inside the basin, the weight of sediments pull against each other and causes them lithify into sedimentary rocks.
Any process that concurs with this analogy is that of erosion and deposition.
