Chromosome 7 may lose an end piece resulting in Williams syndrome, which is an example of a chromosomal deletion.
<h3>What is a chromosomal deletion?</h3>
A chromosomal deletion can be defined as a chromosome rearregement due to the loss of a fragment of the sequence of one chromosome, which leads to the loss of genetic material.
In conclusion, Chromosome 7 may lose an end piece resulting in Williams syndrome, which is an example of a chromosomal deletion.

Answer:
Explanation:
Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 fault lengths distance from the mainshock fault.
Foreshocks are relatively smaller earthquakes that precede the largest earthquake in a series, which is termed the mainshock.
 
        
                    
             
        
        
        
The synthesis of diphenylacetylene from mesostilbene dibromide includes next reactions:
•	Bromination of stilbene-it is the reaction of electrophilic adition and bromonium ion is formed as intermedier (meso compound is the product).
•	Bimolecular elimination-strong base is used in this reaction (takes away the H) and pi bond is formed.
 
        
             
        
        
        
Answer:
To find the volume of a rectangular object, measure the length, width and height. Multiply the length times the width and multiply the result by the height. The result is the volume. Give the result in cubic units, such as cubic centimeters.
