<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:
 spiders are.   generally ectotherms.Their internal temperature depends on external temperature transfer.They are also poikilothermic because the body temperature varies with that of the external environment.,
In animals, individual cells are grouped into  tissues. e,g Blood. The tissues gives rise to organs.
A main function of most types of epithelial tissue is covering surfaces.They line major all hollow surfaces, and covering body surfaces.
Resorption id the movement of fluid from the glomerular filtrate back into the blood. Ions, glucose,and other escaped metabolites are returned to the blood stream.
In humans, goosebumps are a vestige of a mammalian adaptation to thermoregulation. This is a thermoregulatory mechanism to regulate the body temperature,Goosebumps emits heat,  to turn the moisture from the skin  to vapour. This evaporate to release this moisture, which cools the body.

Despite the similarities, methylene chloride (or dichloromethane) is superior to ethylene chloride as an extraction solvent because the boiling point of methylene chloride is lower than the boiling point of ethylene chloride, which allows it to be removed more easily.
