First of all, what is a hotspot?
A hotspot, is a place with a hotter temperature in relation to its surroundings.
So, when we think of "biodiversity hotspot", what exactly does that mean?
It's a place with a higher biodiversity in relation to its surroundings, but also with more concentration of species.
So, that's why forests are considered a biodiversity hotspot. If you want some visual content, try finding a geographical map of Africa. In some desert regions you'll see green spots (some really big). These are forests. The interesting thing about them, is when you search their biodiversity, you'll see what a biodiversity hotspot looks like

Sound waves are slower than electromagnetic waves. Sound waves behave only as a wave, whereby electromagnetic waves act both as a wave and particle, and travel at the speed of light 3.0 x 10^8 m/s d (which is very fast!!!)
Stem cells are undifferentiated cells that could develop to perform a variety of tasks. One type of stem cell is the embrionic stem cell. There are also adult stem cells. To use embrionic stem cell you need to have fertilized embrios. These can be donated to research. The use of the embrionic stem cells is controversial for this reason.
