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.
 
        
             
        
        
        
A zygote will not undergo meiosis
in an environmental state that is not favorable for the zygote’s survival i.e.
the chance of the zygote to survive is not certain. Take for example, chlamydomonas
will form a zygote under normal asexual mitotic reproduction in a favorable environmental
condition. However, under unfavorable environmental conditions the organism
also reproduce sexually to form a zygote but will never proceed to meiotic
division because of the unfavorable environmental state.
