The characteristics of waves are explained below
Explanation:
All waves are a form of a disturbance caused by external vibration that transfers energy and travel from one end to another in a fluid medium.
They involve the transport of energy without transport of matter.
A wave is described by its length, frequency and height (amplitude).
All waves possess the same basic fundamental properties of reflection, refraction, diffraction, and interference.
All waves have a wavelength, frequency, speed, period and amplitude.
Answer: True
Explanation: The importance of mitotic cell division is to produce two daughter cells that are genetically identical. The genetic materials of the parent cell are arranged and moved towards the two spindle poles with the help of the spindles so that there will be an even distribution of the parent cell's genetic materials between the resulting two daughter cells.
The Biological Classification (Linnean) system includes:
Kingdom
Phylum

The best way to remember these is to create your own Mnemonic device. The one I used to memorize these (because you should) was “Kings Play Cards On Fat Green Stools.” This is a very commonly used mnemonic device.

Retrograde means backward and cystography mean to visualize urinary bladder. This examination is used to visualize bladder when there is some obstruction in the urethra. Since a catheter can't be put on through there so it's inserted to bladder directly.
