Fire resistance is where the amount of time that material has withstood a standard fire exposure whereas flame spread is the speed at which a flame spread along the surface of a specific material and is considered as the difference between fire resistance and flame spread.
Fire resistance is the resistance to fire that is for a particular specified time and is under circumstances of standard heat intensity. It will not structurally fail or else allow the transition of heat and also not permit the side away from the fire so as to become hotter than a temperature that is specified well.
Flame spread is described as the surface burning characteristics enhanced by building materials. It is the most tested property of the fire performance of a material.
Firefighters should be aware of the growth and spread of a fire as they face respiratory hazards in emergency situations which include oxygen deficiency, temperature elevation, smoke as well as toxic atmospheres. This can also affect both the physical and mental effects of the firefighter and would be worse if proper respirator precautions are not followed.
This indicates that firefighters are regularly exposed to certain concentrations of hazardous materials that include carcinogenic products such as carbon monoxide, benzene, sulphur dioxide, hydrogen cyanide, aldehydes as well as particulates.

Answer:0.8775
Explanation:formula for gene frequency is p+q=1
where p is the dominant allele and q is the recess allele.
Given than p=0.35
P^2=0.35^2=0.1225
q=1-p
q=1-0.1225=0.8775
Answer is 0.8775
The initial stage of atherosclerosis is characterized by accumulation beneath the endothelium of excessive amounts of LDL.
- The accumulation of lipids, cholesterol, and other chemicals in and on the artery walls is known as atherosclerosis. The accumulation is known as plaque.
- The build-up of lipids and fibrous components in the major arteries is a hallmark of the degenerative illness known as atherosclerosis. A picture of a typical artery's anatomy can be found in Foam cells, or subendothelial accumulations of cholesterol-engorged macrophages, are the earliest lesions of atherosclerosis.
- Nitric oxide and prostacyclin are two chemicals that are produced by your endothelium. These maintain the fluid in your blood and stop it from clotting when it shouldn't. These compounds' insufficient production is a symptom of various diseases, which raises your risk of clotting.
