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.
A bottleneck is very narrow, which means that only a portion of the contents of the bottle cat get out (at the time).
From this effect, people use the word bottleneck when only a few individuals of a population survive:

Answer:
The best answer prompt you should use to avoid copying is that most of the world uses fossil fuels as energy for transportation and that to get rid of using it would take centuries as well as finding a way to provide energy with a renewable source. The use of fossil fuels would negatively affect the biodiversity in neighborhoods and the surrounding environments because the usage of fossil fuels causes pollution to the air, water, and the atmosphere that can lead to other problems.

It's just simple logic but can be confusing at first read the question and think about it to help.
