Explanation:
a living system is a system in an organism consisting of organs. each organs carry out different functions to ense life processes can be carried out effectively. The function of the organs are determined by the cells which make up the tissues. The connections are important to remove wastes/toxins out of the body and help absorb nutrienys, in some cases produce hormones as a form of homeostasis to ensure the body remains in a healthy optimised state constantly.

<h3>What is wave?</h3>
Wave is a periodic <u>disturbance</u> that moves away from a source which carries <u>energy</u> with it. Waves can be typified according to the <u>direction</u> of motion of the vibrating particles with respect to the direction in which the waves travel and according to <u>medium</u> .
<u>Longitudinal</u> waves vibrate perpendicularly to the direction in which the waves travel. This wave exhibits up and down motion. Longitudinal waves vibrate <u>perpendicular</u> or back and forth to the direction in which the waves travel.
<u>Electromagnetic</u> waves are combination of transverse and longitudinal waves. These move in a circular pattern as the waves pass by.
<u>Mechanical</u> waves need solid, liquid and gas medium to propagate or travel. Transverse, mechanical and surface waves are examples of mechanical waves.
Electromagnetic waves do not need <u>medium</u> to propagate. Radio waves, ultraviolet, infrared, and gamma rays are examples of <u>electromagnetic</u> waves. The nature of waves can be described through its terms, quantities and <u>propagation</u>.
The <u>crust</u> and trough refer to the highest point and lowest point of a wave pattern, respectively. The <u>magnitude</u> of a transverse wave is the maximum displacement of a particle of the medium on either side of its normal position when the wave passes. The frequency of periodic waves is the number of waves that pass a particular point for every one second while the <u>Amplitude</u> is the distance between adjacent crests or troughs.
The period is the time required for one complete wave to pass a particular point. The <u>speed</u> of the wave refers to the distance the wave travels per unit time. It is related to the frequency of the wave and wavelength through the following equation: wave speed= frequency x wavelength.

Answer:
Education
Explanation:
Education is not among the top sources of stress for Americans according to the American Psychological Association. The American Psychological Association is an organization that represents psychologists in the United States. The APA researches various matters like abortion, human rights, detainees and so on. In 2010, the APA conducted a survey on stress and their findings include there is high stress in America; self-care isn’t a priority and lack of will power and concludes that work, health, and money are the top sources of stress in America.
