Alfred Wegener suggested the Continental Drift Theory.
However, this idea was dismissed by scientists. Continental Drift Theory states
that all continents were once joined together then they drifted away from each
other. It was backed by maps which showed that if continents were pulled close
together would fit each other perfectly, just like in a puzzle. However
scientists from different fields resisted the idea and accused Wegener of not being an expert of science. The strongest reason of the
rejection, however, was that Wegener could not explain how continental drift
happened.
<u><em>-Why does the lysosome have a different pH than the cytoplasm? </em></u>
The pH within lyosomes is more acidic than the pH of the cytoplasm because Enzymes within the lysosomes aid the breakdown of proteins, polysaccharides, lipids, nucleic acids, etc. These enzymes are active at a much lower pH than that of the cytoplasm. Thus the different pH from the cytoplasm.
<u><em>-What is the advantage of having several smaller chloroplasts and not just 1 huge one?</em></u>
The advantage of having several smaller chloroplasts and not just 1 huge one increases the surface area for the light to be absorbed. As a result, more light energy can be utilized.
Answer:
1/1000 or 0.001
Explanation:
Serial dilution refers to the systematic dilution of the known concentration through successive suspension of initial volume to a fixed value of diluent.
In the given question, the serial dilution is performed in which the dilution factor will be
DF= volume of added solution / total volume of solution
For tube A
= 1/ 1+9
=1/10 or 10 folds.
For tube B
= 1/10 x 1/10
= 1/100 or 0.01
For Tube C
= 1/10 x 1/10 x 1/10
= 1/1000 or 0.001
Therefore, total dilution of tube C will be 0.001 or 1/1000.
Answer:
<em>The correct answer is the option on the upper right .</em>
Explanation:
Aquatic birds that require fresh water to thrive need to be around a source of fresh water. The wetter island has more fresh water than the drier island. This means that both island will be occupied from a population of zero, to an optimum stable population, which is indicated as the graph moves from zero to its maximum point, and then levels out. Th drier island will have the same pattern of curve, but will only be able to support a much smaller population, which is why the curve for the drier island is less than that of the wetter region.
