Answer:
Heat stroke is acquired during extreme physical exercise when the environment is hot, strenuous activity, excess clothing and tight clothing, drinking alcohol and smoking during a hot season or environment,when you are dydrated and not drinking water. Some medication and age also add to having heat stroke. 
It causes disrupts in the feedback loop because it doesn't form a circular chain. It can be both positive and negative chain. Feed back loop is known to be either negative or positive channel or pathway formed by an effects. 
The impact and disruption it has on human physiology 
1.it causes brain damage 
2.it leads to death 
3.it also causes vital organ damage
Explanation:when the environment is hot, it makes you heat up fast when exercising and increase your temperature because the atmospheric temperature is high,and when exercising in this condition without air conditioner to cool your surroundings it leads to heat stroke. 
When wearing heaving clothing and tight clothing during physical exercise it makes you to not lose moisture and makes air not easily passed to you, this causes your body to heat up fast and thereby causing heat stroke. 
When dydrated and not drinking water causes you to overwork you body and not cool it down, it leads to heat stroke. 
Heat stroke causes brain damage, leads to death when not taken immediately or rush to the health center or hospital. 
 
        
             
        
        
        
Answer: A. Geological processes continue over millions of years.   
A swamp is a wetland which exhibit the growth of vegetation. It consist of vegetation which is being dominated by trees. When these trees die, the wooden parts sank below the water. The wood remains being deposited at the bottom of the water body causes the formation of coal. Coal formation results due to the wood being compressed and buried. It takes millions of years for the transformation of wood into coal in the geosphere of the swamp region.
Hence, formation of coal is a geological process and it takes millions of years for it's formation.

Demography is the statistical study of human populations. Demography examines the size, structure, and movements of populations over space and time. It uses methods from history, economics, anthropology, sociology, and other fields.
 
        
             
        
        
        
Cell membrane protects animals cells from harmful chemicals.
Explanation:
The cell membrane is a tough covering composed of the phospholipids and proteins and forms a bilayer around the cells. This acts as a semi-permeable membrane and controls the transport of ions, organic molecules and solutes to and from the cell through selective permeability.
The hydrophilic and hydrophobic properties and the corresponding polarity of the cell membrane and ionization status of the chemicals prevent the entry of harmful substances into the cell. The cell membrane functions as a barrier system and prevents the flow.
