There are three possibilities. First, and more common, is that the image went out of focus and appeared blurred. This can be solved by adjusting the focus using the fine adjustment knob. Second, the image of interest is now outside of the respective visual field of the said magnification. This can be solved by finding the image of interest again using the stage control knobs. Lastly, both of said scenarios may have happened simultaneously. Rarely, the high power objective (100x) scope may hit the glass slide and break it.
Answer:
1) Waterfalls also create erosion. Soft rock erodes, leaving a hard ledge that it washes over. Rocks fall over the waterfall and swirl around in the pool, creating more erosion. The process is repeated, and the waterfall retreats, leaving a gorge behind.
2) Coastal erosion from oceans is always occurring. An eroding beach can lose several feet of sand in one year. In California, waves and rain create mudslides that take down houses by the dozen.
Viruses depend on the host cells that they infect to reproduce. ... When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products.
Answer:
B. WW or Ww
Explanation:
If the w allele is recessive, that means that the presence of any W alleles will mask the expression of the w allele. So the possible genotypes for no spots and hence solid coat, keeping in mind that there must be two alleles, one from each parent, are WW or Ww.
WW or Ww would both produce phenotypically solid coats. ww would produce a spotted coat.
