Students hypothesized that adding lactose to a sixth test tube would produce the greatest amount of carbon dioxide.
This is because lactose is a sugar molecule that is the food source for the yeast.
Fermentation is a metabolic pathway that occurs anaerobically, meaning in the absence of oxygen (O2). It includes the process of glycolysis with some extra reactions which make alcohol.
 
        
                    
             
        
        
        
You should mix 
4µl of DNA sample and complete it with 
96µl (100-4) of water.
You can figure this out by using  
C1.V1 = C2.V2C1 = 250 <span>ng/μl (Sample Concentration)
</span>V1 = ?        
  (the necessary volume to take from the DNA sample)C2 = 10 <span>ng/μl (PCR concentration)
</span>V2 = 100 µl (total volume)
V1 = 

 = 

 = 
4µl
For the water: 100µl (total volume) = 4µl + Water
Water volume = 96µl
 
        
        
        
Answer:
An example of juxtacrine signaling is exemplified by the activity of some cell adhesion or ECM proteins, such as laminin, that do not just allow a cell to move over them, but act as signals to promote increased motility

I think in someway social hazards do affect you. But then again you choose who you are and how you choose to react to things. Seeing things like the walkout on social media might make you happy that kids are standing up against gun control. But then you could see the news of syria kids, and you could immediately feel depressed or sad. I know social media has definitely made me feel insecure and lonely, makes other people's lives look better than mine.<span />
