An electron microscope is very powerful and allows you to see very tiny, thin specimens. The question makes it seem that you looked through both types of microscopes at specific samples? As for how they would differ, a light microscope's level of magnification is limited by the physical characteristics of light and therefore can only see objects as small as organelles inside of a cell. A scanning electron microscope, however, does not use light, it uses a beam of electrons to visualize the sample. Electrons are much smaller than the light beam and are able to image much smaller objects, such as molecules and atoms.

Answer:

  • The organism previously used 15N for replication so all the DNA molecules were of 15N15N type. Then the organism is shifted to a medium where only 14N is available for replication.
  • According to semi conservative mode of replication, a newly synthesised DNA molecule consists of one new strand and one parental strand. So after the first round of replication, All the 15N strands will synthesise new DNA strands using 14N resulting into intermediate 15N14N DNA molecules. Hence, only one band would be observed (15N14N) above the original 15N15N band since 15N14N has lighter isotope too so it will be lighter than 15N15N molecules and will lie above it.
  • After second round of replication, 15N strand from 15N14N would synthesise another 14N strand. 14N strand from 15N14N molecules will also synthesise another 14N strand. So now, 50% of the DNA molecules will be of 15N14N intermediate type and 50% of them will be of 14N14N type.Two bands will be observed above the original 15N15N band. One band of 15N14N molecules will be right above it and other band of 14N14N molecules will be even higher because it is the lightest band since it has only the lighter isotope of nitrogen.

Part B: Research (11 points) In part B you will be doing some research on desertification.
Goryan [66]
Okay so northern Africa and the Sahara desert is the best example of desertification.
2 ways humans have contributed to that is: 1) pastoral nomadism 2) little to no settlements to increase water supply 

how it impacted the environment: so now the environment there is sandy, only organisms adapted for those extreme environment can live there ex. camel, cactus, etc., 

how it impacted quality of life: quality of life diminished, not enough water to sufficiently feed the populations, people live in extreme poverty, people are moving away, and the climate is very dry and hot, pretty much not a place anyone would want to live
