Answer:
It will take 83 days to recover the extra cost
Explanation:
To determine the length of time it will take to recover the extra cost, it will be logical that we compare the $200 extra cost to the total savings in running cost made for a year and covert this into days
The total savings in running cost is the cost savings per hour multiplied by the number of hours in a year.
The calculations are set below:
Savings in running cost per hour = $0.1
Total savings in a year = 365 days × $0.1 × 24 = $876
Extra cost of Energy Star refrigerator = $200
If total savings for a year is $876 , then equivalent length of time to save $200 would be
Length of time = 200/876 × 365 days = 83 days
It will take 83 days to recover the extra cost

Answer:
The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock
Explanation:
This layering is a result of the process of metamorphism. Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically
Explanation:
An organisms <u>genes </u>are located on threadlike structures called chromosomes.
Genes are a set of coded instructions in the form of DNA, which are crucial to cell regulation- these enable protein synthesis.
Further Explanation:
Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and carry out protein synthesis.
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
