A patient will be at increased risk of postpartum bleeding or hemorrhage if the baby she gives birth to is very big. The time spent in labour is also important. If the woman labor for a long time before giving birth, she may have increased risk of postpartum bleeding.
We can say that the amount of time it takes a car to reach a certain velocity means that some have less air resistance than others.
Both starch in plants and fat cells in animals serve as a store of energy. However, fats in animals are generally stored in fat cells (forming the adipose tissue) while starch in plants is stored in the chloroplasts. Also, fats and starch are 2 totally different compounds with different chemical compositions and structures (I won't elaborate on the types of fats and starches in this thread though).
One of the reason that matter is able to move around within the earth is THE INTERACTION BETWEEN MATTER AND ENERGY.
The major source of energy on the earth is the sun. The heat energy from the sun is used to drive many chemical reactions on the earth. When the heat energy of the sun heat up a matter, it increases its temperature and causes the particles in the matter to move with greater motion until phase change occur. For instance, when the sun heat up water in the ocean, the particles of the water move about with great energy until they escape into the atmosphere in form of vapour.
