Answer:
a radio uses the reflections of a coil of wire placed in a permanent magnetic field.
Answer:
Option A. Because of the soot covering everything, the dirtier darker moths will be eaten less often, allowing them to reproduce and pass their genes on to the next generation.
Explanation: Sooth is the black powder which is produced due to incomplete combustion of carbon containing compounds. In the england, before industrial revolution, the population of white peppered moth were high due to clean environment and unable to see by the birds during night. When industrial revolution occurs, there is sooth spread on all the trees which is black in color so the population of black peppered moth increases because they can't be seen in the dark by the birds and population of white peppered moth decreases due to easily seen by the birds.
<em>Active transport</em><em> uses </em><em>cellular energy</em><em> to </em><em>move molecules</em><em> based on the </em><em>concentration level</em><em> and </em><em>Passive transport doesn't</em><em> require </em><em>energy</em><em> to </em><em>move molecules within</em><em> their </em><em>cells</em><em>.</em>
<u>EXPLANATION: </u>
Active transport uses cellular energy for this movement. It uses energy stored in ATP to begin the transport. This means that the molecules transfer from an area where it is less in number to an area with a high concentration of molecules.
But Passive transport specifies the movement of molecules across cell membranes which doesn't require energy as it depends on the cell membrane's penetrability. Molecules just have to circulate in or out of the cell.
