Hello! ATP stands for adenosine triphosphate, and ADP stands for adenosine diphosphate. The difference between the two molecules is that ATP has three phosphate group, and ADP has two phosphate groups. ATP is an unstable molecule, which means it will release energy when it becomes reduced to ADP, meaning it will break off one of its phosphate groups. Hope this helps, and let me know if you have any questions! ^-^
Answer:
Cancer cells ignore these cells and invade nearby tissues. Benign (non-cancerous) tumors have a fibrous capsule. They may push up against nearby tissues but they do not invade/intermingle with other tissues. Cancer cells, in contrast, don't respect boundaries and invade tissues.
Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not
<u> The cork initially has some potential energy when it is held above the water (the greater the height, the higher the potential energy). When it is dropped, such potential energy is converted to kinetic energy as the cork falls. When the cork hits the water, that energy travels through the water in waves.

Explanation:
In this lab, you will take measurements to determine how the amplitude and the period of waves are affected by the transfer of energy from a cork dropped into the water.
The cork initially has some potential energy when it is held above the water (the greater the height, the higher the potential energy).
When it is dropped, such potential energy is converted to kinetic energy as the cork falls. When the cork hits the water, that energy travels through the water in waves.
Materials :
- large bowl or basin
- water
- cork (or ping pong ball)
- stopwatch
- measuring tape
- Fill a large bowl or basin with water and wait for the water to settle so there are no ripples.
- Gently drop a cork into the middle of the bowl.
- Estimate the wavelength and the period of oscillation of the water wave that propagates away from the cork. You can estimate the period by counting the number of ripples from the center to the edge of the bowl while your partner times it. This information, combined with the bowl measurement, will give you the wavelength when the correct formula is used.
- Remove the cork from the bowl and wait for the water to settle again.
- Gently drop the cork at a height that is different from the first drop.
- Repeat Steps 3 to 5 to collect a second and third set of data, dropping the cork from different heights and recording the resulting wavelengths and periods.
- Interpret your results.
