Answer:
True 
Explanation:
The stratosphere is the layer of the earth’s atmosphere which is above the troposphere and below the mesosphere.
The stratosphere contains about 90 percent of the ozone layer. The stratosphere is made up of ozone layers which helps in the absorption of about 95 percent of the ultraviolet rays from the sun and converting to heat. 
This is the reason why depletion of the ozone layer found in the stratosphere gives rise to global warming.
 
        
             
        
        
        
Answer:
arrow (which creates the resultant vector)
Explanation:
When you use the graphing technique when adding vectors, you can use the head to tail method to draw the vectors. And from the starting point or the tail of the first vector you drew, you will draw an arrow touching heads with the head of the last vector drawn. 
With that, you can use a ruler to measure the resultant vector's magnitude, and use a protractor to measure it's direction. 
Below is an example:
Let:
V1 = Vector 1
V2 = Vector 2
R - resultant vector. 
 
        
             
        
        
        
A chromosome is a packaged and organized structure containing most of the DNA of a living organism.  Messenger RNA  is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.  Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
