I am not really sure are there multiple choice questions if so I need to see them.
It is false to that question.
The correct answers to fill into the blank spaces are;
<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:
Artificial selection
Explanation:
Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Bladder spinal reflex is the mechanism so you can
consciously void urine. There are receptors in the bladder that senses the
amount of urine collected. These are responsible for that ‘voiding urge’. The
higher the amount of urine collected, the greater the intensity of the signals.
Finally, when you get to the bathroom,
another set of nerves lets you consciously urinate so you can select which bathroom
stall is nice for peeing. Diabetes mellitus can damage nerves in the spinal
cord, including those involved in functioning of the bladder. Damage to the nerves
in the bladder spinal reflex arc is suspected if the patient suffers from
urinary retention – where the patient can consciously void urine but cannot
feel if the bladder is full.
