Fault-block mountains form when Earth's crust pushes material up and down near a fault line.<span> Rocks that get pushed upward eventually form mountains if there is enough seismic activity. The higher part of a fault-block area is called a horst, while the lower part is called a graben, according to Ducksters.

The answers is D because it needs something to survive
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.
Without seeing the image ...I can suggest C as bacteria and archae are the most similar besides all other options ! am I right !!!
The two ways the endocrine system and the nervous system are different in communication, is that the nervous system responds rapidly to short-term changes in the body by sending electrical impulses. And with the endocrine system, it takes longer, so it's a long-term effect until it notices any changes and when it does, it sends chemical messengers known as hormones into the body.
Now, how they are similar, is because both the nervous and endocrine systems work together to maintain homeostasis.
