Answer:
the last option is the best
Explanation:
no idea that will ever pass without disagrement from other scientists who generate and defend the opposite ideas
<span>The main difference of renewable and non-renewable resources lies in the capacity of
the environment to replenish itself. Renewable resources are resources that can
be easily replenished by the environment over a short period of time, while
non-renewable resources take more time. <span>
Examples
of renewable resources are solar energy, harnessing the sun's power that shines
day to day. Wind energy that exists naturally is also a renewable source.
Geothermal energy, heat coming from the center of the Earth, and Biofuels,
fuels made from living organisms, are all renewable energy.
<span>Non-renewable
energy resources are the fuels we use in our cars, minerals from the soil,
coal, among others are supplies that also come from Earth. These are all materials that might take a long time (probably millions of years)
to be fully restored. </span>

Answer:
a. Bands at 1kb, 6kb and 8kb
Explanation:
The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.
The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.
In the given question, the
1. EcoRI- produces two strands of 7 kb and 8 kb
2. BamHI- produces two strands of 1kb and 14kb
This shows that the length of DNA sequence is 15kb
But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:
i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb
ii) 1 kb band is already produced by the Bam HI.
This shows that 1+6+8= 15 kb
Thus, Option-A is correct.
