<u>Cell culture i</u>s the method applied by scientists to grown, cells in the laboratory setting to study the cells for particular reasons.
Explanation:
Cell culture is basically a method for survival, reproduction etc which are done under controlled conditions in the space outside the environment. This is also used for data mining.
 Purpose: Cell culture is used for propagation of virus 
Advantages:
- Vaccine production by replication of virus
- Detection of viral cell of virus
- Convenient easy and economical method
Disadvantages
- Maintenance of sterile aseptic conditions.  
- Increases microbial contamination
- Cross contamination takes place
 
        
             
        
        
        
Answer:
a twelve-point scale for expressing the local intensity of an earthquake, starting from I virtually imperceptible to XII (total destruction.
 
        
             
        
        
        
The conversion you'll need is:
1 cL = 0.0001 hL
 
Since we have 34.9 cL, multiply 34.9 on both sides of the equation above. 
You should end up with 34.9 cL = 0.00349 hL
Hope this helped ^-^
        
             
        
        
        
Answer:
The third option, Light intensity has an impact on the rate of photosynthesis.
Explanation:
Light is a limiting factor at low intensity. Thus the rate of photosynthesis increases with an increase in light intensity. High light intensities affect the rate of photosynthesis. It increases the temperature of the leaves. Therefore, rate of transpiration increases
