Answer:
it is expected to observe two bands: one band of light density and one band of heavy density
Explanation:
DNA replication is semiconservative because when DNA is replicated both resulting DNA molecules are composed of one original strand and one newly synthesized strand. If DNA replication would be conservative, then the original DNA molecule would serve as a template to produce a new DNA molecule, thereby each cell division would produce one daughter cell with a new DNA molecule and one daughter cell with the original DNA molecule of the parental cell. In this case, the transfer of bacteria-like organisms into a heavy 15N medium would produce two types of DNA cells after replication: cells with original DNA of light density (14N) and cells with new DNA of heavy density (15N), which would be distributed in two bands after centrifugation.
The soil on the valley floor because it would not have runoff. Hope this helps.
The answer is protein synthesis......
A limiting factor in ecology refers to the resources in the environmental conditions, which restrict the growth, distribution, or abundance of an organism or a population of organisms in an ecosystem.
In the given situation in Atacama Desert, water is a limiting factor as due to the scarcity of water the plants are having a tough time growing, which restricts the number of plants found in the desert.
