You can determine density using mass and volume.The equation for that would be D=m/V, which is Density is equal too mass divided by volume. I hope this helped you out!
<u>Potential energy</u> is the chemical energy stored in the chemical bonds of atoms and molecules.
<h3>What is potential energy?</h3>
Potential energy is the energy stored in the bonds (structural arrangement) of chemical compounds, such as atoms and molecules.
<h3>Characteristics of potential energy</h3>
- The potential energy that a molecule may have is due to the forces of attraction and repulsion with other molecules in its environment.
- An example is glucose, which stores chemical potential energy that the body, through metabolism, transforms into heat energy to maintain body temperature.
Therefore, we can conclude that potential energy is stored in the chemical bonds of molecules.

Basically we can divide the whole cycle into 6 phrase. menstruation, repair phrase, ovulation, receptive phrase, and pre menstrual phrase, all in this order.
usually a cycle takes around 28 days, but it can sometimes be longer or shorter depending on different women.
for around the first 5 days (again, it's not exact days) it's menstruation, uterus lining is shed out from the vagina. this only occurs if fertilisation and implantation does not take place.
then for the next few days, it's the repair phrase, oestrogen helps repair the lining of uterus, to thicken it up, to prepare for fertilisation and implantation, a place for the fetus to develope.
next 3 days will be ovulation, where the ovary will release one mature egg (but sometimes 2 or none) into the oviduct, the egg can only survive for a few days so if fertilisation doesn't occur during this phrase, menstruation will occur that cycle.
next will be receptive phrase, where the lining keeps on thickening, and the thickness is maintained by progesterone, another female hormone.
at last it's the pre menstrual phrase, lining will start to degenerate unless implantation ocured.
hope this helps
