If the average person blinks 25 times per minute you have to multiply and times it by 60(which is an hour) to equal {1,500} . Next times the number 1,500 by 24 because that is how many hours are in a day so that would equal {36,000} times a day. Now times 36,000 by 7 because that is how many days of the week so {252,000} is the answer per week.
Now to figure out how many times we blink in a year we will multiply
252,000 by 52 because there are 52 weeks in a year.
You get the answer 13,104,000
So you blink 13,104,000 times in a year.
Hope this helps

Explanation;
Refrigerants are divided into two groups according to toxicity:
-Class A signifies refrigerants for which toxicity has not been identified at concentrations less than or equal to 400 ppm; and
-Class B signifies refrigerants for which there is evidence of toxicity at concentrations below 400 ppm.
They are also divided into three groups according to flammability:
-Class 1 indicates refrigerants that do not show flame propagation when tested in air at 21°C and 101 kPa;
-Class 2 indicates refrigerants having a lower flammability limit of more than 0.10 kg/m3 at 21°C and 101 kPa and a heat of combustion of less than 19 kJ/kg;
-Class 3 indicates refrigerants that are highly flammable as defined by a lower flammability limit of less than or equal to 0.10 kg/m3 at 21°C and 101 kPa or a heat of combustion greater than or equal to 19 kJ/kg.
-Therefore; the answer for the above question would be Class B and class 3.

Explanation:
Alleles exhibit dominance over each other leading to the dominant one being express and the recessive one not expressed. Alleles are variants (different) genes that codes for a specific trait.
At Anaphase 1 homologous chromosomes separate leading to each being pulled to the opposite pole and the sister chromatids remain together while the homologs experience segregation.
Dominant trait is the one that is expressed. It usually exercise dominance over recessive trait until it is removed from the recessive trait and replaced with another recessive gene before it is expressed.
