Answer:
D. Nitrogen-14 has 7 electrons, 7 protons, 7 neutrons nitrogen-15 has 7 electrons, 7 protons, and 8 neutrons
Explanation:
In an atom, number of electrons is equal to the number of protons. And the number of neutrons is equal to the difference between the mass number of the atom and the atomic number. For Nitrogen 14, electron is 7, proton is also 7 as number of electrons and number of protons are equal. So, the neutron will be 14-7= 7. For Nitrogen 15, electron number is 7 so proton number will be also 7. Neutron number for nitrogen 15 will be 15-7= 8. That's why the answer is option number 4.

The answers include the following:
- The maps show that northern areas should get more precipitation, regardless of emission levels.
- Southern areas will likely get less precipitation, regardless of emission levels.
- These maps to prepare for natural disasters in the Great Plains, scientists need to ask how can we protect people and property in the event of a flood or a drought.
<h3>What is Drought?</h3>
This is referred to a period in which there is shortage of water due to reduced rainfall.
This leads to decrease in food production and the map patterns will help protect the people.
