In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.
Let's assume the cost for natural gas is $15.00 per 1,000 cubic feet. This means that $15.00 will purchase approximately 1.03 million BTU's of energy. This would be equivalent to 11.26 gallons of propane. At $2.50 per gallon of propane, natural gas would be a more cost effective energy solution. Breaking it down even further, natural gas needs to be more than $28.00 per 1,000 cubic feet for propane to be a more cost effective energy solution (provided the cost for propane is $2.50 per gallon.
How does the cost of propane rank against oil, natural gas and electricity? First, it is important to note that each of these fuels generates heat differently. One gallon of heating oil burned with 100% efficiency would generate 138,690 BTU of heat. One gallon of propane burned with perfect efficiency would generate a mere 91,333 BTUs of heat.
