The study of earthquakes is seismology. Scientists (seismologists) use instruments to record the strength of earthquakes in an area. The instrument that is used to measure seismic waves is called seismograph. <span>It records the shaking of the Earth. </span>The size of an earthquake is measured with its magnitude and intensity.
Answer:
Similarities:
Both natural selection and evolution work on genetic traits in populations rather than individuals. Both natural selection and evolution are involved in generating changes over generations. Both natural selection and evolution result in either extensions or death.
Difference:
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes
Answer:
Nervous system
Explanation:
The nervous system can be divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The autonomic nervous system is a part of the PNS which is concerned with the control of involuntary physiologic processes. During the exercise, the sympathetic nerves of the autonomic nervous system are in charge of preparing the body for physical activity by increasing the respiration rate, heart rate and blood pressure. The sympathetic nerves can also increase energy for the muscles by reducing insulin release and increasing blood glucose.
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
