Answer:
easy to produce, affordable, abundant
Explanation:
A non-renewable resource is defined as the natural resources which are not ereadily replaced through natural means and it takes thousands of years for their renewal. Example of non-renewable resource include Fossil fuels such as natural gas, oil and coal.
<u>There are many advantages of non-renewable resources such as:</u>
1) Easy to produce: non-renewable resources are easy to produce because processing stations can be easily developed for refinement and distillation of non-renewable resources.
2) Affordable and abundant: non-renewable resources are affordable and abundant in the earth. for example diesel and oil are good choices for powering vehicles.
Hence, the correct options are easy to produce, affordable, abundant.
An exothermic chemical reaction is change in the chemicals that can never be undone, an exothermic solution is a combination of chemicals
The two enzymes that are used during DNA replication is helicase
and polymerase. Each enzyme has distinct role that made it a vital part of the replication.
In the course of DNA replication, the initial stage is to unzip the double
helix structure of the DNA molecule by the enzyme helicase, which breaks the
hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a
DNA template. This enzyme binds to the leading strand and then adding a new
complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of
deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.
