Answer:
The two components that helps to maintain the homeostasis of the cell are 1  Buffer system 2 Membrane transport process 
Explanation:
1 Buffer system Buffer system helps to maintain a constant PH in addition to small amount of acid or base .There are many buffer system present inside  our body 
A Bicarbonate buffer system helps to maintain concentration of carbon di oxide, bicarbonate ion and Carbonic acid according to our body"s need.
B Phosphate buffer system 
C Hemoglobin buffer system  This buffer system helps too maintain normal O2/CO2 ratio of our body which is very much important of maintain our body"s homeostasis.
2 Membrane Transport process  Various ion channels of plasma membrane sych as Na+ K+ ATPase,Ca2+ATPase ,H+ ATPase helps maintain ionic homeostasis of our body.
 
        
             
        
        
        
Heath index chart is the best indicator you should use when determining if you should modify activity for heat. The "heat index" is a single value that looks for both temperature and humidity. The higher the heat index, the weather will feel the hotter since sweat does not immediately evaporate and cool the skin. The heat index used is much better than air temperature alone for estimating the risk to workers from environmental heat sources.
