The three evidences that Murchison cites to prove that Jonas’s tumor did not arise from the cells of his own body are DNA sequencing, the DNA of cancer cells from all numerous Tasmanian devils were the same, the cancer spread through bite of the devil.
Explanation:
Elizabeth Murchison, an Oncology geneticist, conducted various researches to study about the spread of contagious cancer among Tasmanian devils.
Murchison conducted research on various devils like Jonas, Kimbo and studied how the cancer spread and invaded the devils.
The first thing that Murchison discovered was that the DNA sequence of the tumor cells was different from that of his own cells in his body. Further genetic profiling proved that the tumor cell sequence was similar to some other Tasmanian female devil, while the Jonas devil was a male.
The next thing she found was that all the cancer cells sampled from numerous Tasmanian devils were sharing the same DNA, which meant that it was spreading among the population of devils.
Since the Tasmanian devils are ferocious and bites each other, cancer must have spread through the saliva of each animal
Thus, Tasmanian devil cancer is a unique type of cancer that does not rise from one’s own cell but by spreading among its own population.
Answer:
Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
Explanation:
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
