An example of potential energy is 1. The air in an inflated balloon.
Potential energy is stored energy. The air in the inflated balloon has elastic potential energy because it is being stored in the ballon. If the mouth of the inflated balloon is released or if the balloon is popped, the potential energy in the balloon transforms into kinetic energy.
All of the other answer choices are examples of kinetic energy or energy in motion. The wrecking ball, boulder, and water are all moving which means that they all contain kinetic energy, not potential energy.
KAH: 45 - 15 = 30 degrees
Answer:
They can <em><u>grow into any type of body cell.</u></em>
Explanation:
Stem cells are immature cell types- they are somatic cells, that contain the entire genome of an organism. The genome is made up of DNA, which encodes instructions for the cell.
These may potentially become various other types of cells through the process of differentiation and reach maturity. In differentiation, chemical signalling, and gene expression ultimately determine the cell's fate.
While scientists have made enormous discoveries, there is always more to learn. Knowledge is built on and reviewed. Sometimes new information reveals an error in understanding from the past. The study of how the world works is always ongoing.
