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.
True because when you have a gene it replicates.

b. Natural selection is an example of the major mechanism by which evolution occurs
Explanation:
The concept of evolution are both closely related in that natural selection is the major mechanism by which evolution occurs. This was proposed by Charles Darwin after his journey to the Galapagos Island on the HMS Beagle.
- Evolution is the change in the characteristics of an organism over several generations.
- Organisms evolved to in order to be at an advantage and naturally favored.
- According to Charles Darwin, organisms evolved by the process of natural selection.
- Natural selection is the process by which an organism becomes adapted to its environment.
- Organisms with desirable trait are naturally favored with competitive and reproductive advantage in the environment.

Explanation:
Vertical farms attempt to produce food in challenging environments, like where arable land is rare or unavailable. The method helps mountainside towns, deserts and cities grow different types of fruits and vegetables by using skyscraper-like designs and precision agriculture methods.
