Explanation:
Cells generally have a relatively short lifestyle in that they grow, divide and then die off. This is not the case with cancerous cells as those ones mutate and then multiply such that they eventually form a tumor.
Looking at the graph, most of the cells are remaining at a lower or manageable number because they are dying off. Cell A on the other hand is simply increasing in number which means that it is a cancerous cell as it is increasing its number by mutating instead of dying off like other cells would.
A plant cell has chloroplasts.
An animal cells doesn't.
Answer:
Devegetation affect the nutrient reservoir and watershed due to not using of nutrient and increases soil erosion.
Explanation:
Devegetation refers to no vegetation on a piece of land.

Devegetation also affect water quality of watershed. Erosion is the main problem of those areas where there is no vegetation and the upper layer of soil is washed by the rainfall.
