Answer
:When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation). ... When the pressure exerted on a substance increases, it can cause the substance to condense.
 
        
             
        
        
        
During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase. ... Cohesin forms rings that hold the sister chromatids together, whereas condensin forms rings that coil the chromosomes into highly compact forms.
        
             
        
        
        
The answer would be d because the genes come the two parents 
        
             
        
        
        
The significant role of spore formation in the reproductive cycle of this bacterium would be to allow the bacteria to survive in extreme conditions. The spore formed is called an endospore which is a thick cover made of protein. These spores are mostly resistant to heat and chemicals which makes the bacteria survive in harsh conditions. Spores can only be destroyed by sterilization and it require very high pressures and very temperatures. In microbiology and medical settings, this process is usually done in a device known as the autoclave. Sterilization is a process that involves the killing of all microorganism in a system whether it is harmful or beneficial.
