The __________________ have no charge but weigh a lot compared to the ________________. The proton has a __________________ charge. In order to get the atomic mass, add the number of ________________ and _________________ together
The electron has a negative charge. The electron is smaller than the other particles and can be found outside of the nucleus, which is another name for the center of the atom. In the center, there are protons and neutrons. The neutron have no charge but weigh a lot compared to the electron. The proton has a positive charge. In order to get the atomic mass, add the number of protons and neutrons together.
The following are the two considerations demonstrating that there would be less biodiversity than the tropical areas in the Mediterranean climate as well as polar areas.
The first reason is all tropical areas experience drastic temperature variation.
The second reason is early in the earth's history, the northern latitudes are inhabited.
