<span>The
answer is A. The reduction in variety reduces the number of alleles for
each gene in the gene pool. This reduces the variations in the phenotypes of the crops. A disadvantage of this phenomenon is that it
would be difficult for the crops to withstand
environmental changes and calamities because there is no wide variation on
which natural selection could act upon to
enable the crops to adapt to these changes.</span>
Answer:
A cell will shrink when the concentration of electrolytes is greater inside the cell than outside the cell.
Explanation:
<em>When the concentration of electrolyte is greater inside the cell than its outside, water molecules move from the outside electrolyte into the cell leading to its expansion and turgidity. If the water movement continues, the cell may burst and release its contents in a process known as lysis.</em>
Hence, that a cell will shrink when the concentration of electrolytes is greater inside the cell than outside of the cell is false.
Answer:
divergent plate boundaries
Explanation:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
