The cells are different between the different layers of a bone because each layer protects something different than the rest.
Answer: D. NE producing cell bodies are found in widespread brain regions
Explanation:
Norepinephrine (NE) is a chemical in the body that exists naturally and acts as both a neurotransmitter and a stress hormone. When the brain perceives that there has been a traumatic occurrence, it is released into the blood as a stress hormone.
Norepinephrine is produced in the inner part of the adrenal glands which also produces adrenaline.
Hence, NE is only found in inner part of the adrenal glands and the correct option is D.
Answer:
With monoculture crops, it messes up the natural balance meaning genetic diversity is lower.

The question to the above information is;
What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?
Answer;
An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
Explanation;
-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.
J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:
- atoms are spheres of positive charge
- electrons are dotted around inside
