Topics Atomic Number, Central & Peripheral Nervous Systems, Element, Species, Stratosphere

Study Guide

Atomic Number

The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.

Central & Peripheral Nervous Systems

The nervous system consists of the brain and spinal cord (central nervous system) and the peripheral nervous system which is the network of nerve cells (neurons) that collect and distribute signals from the central nervous system throughout the body.

Element

An element is matter than cannot be separated into different types of matter by ordinary chemical methods.

Species

The narrowest classification of life, species, contains organisms that are so similar that they can only reproduce with others of the same species.

Stratosphere

The stratosphere is just above the troposphere and is stratified in temperature with warmer layers higher and cooler layers closer to Earth. This increase in temperature is a result of absorption of the Sun's radiation by the ozone layer.
