When the coal reaches its hardest and the darkest form then it is termed as anthracite.
Answer: Option D
<u>Explanation:</u>
The hardest among the coal is called as the anthracite. It has large amount of carbon atoms and it is also regarded as the best quality of coal that is being mined.
This is mostly prevalent in South Korea, North Korea, United states, United Nations, Canada etc. This is mainly used in the steel making process and is combined with many alloys for enhancing their property.
B because you can’t make the ants go a cartoon way.
It’s depends on the amount of light they like.
Answer:
45 times
Explanation:
There are 4 nucleotides. The probability of finding one particular nucleotide (e.g. A) is 1/4.
The probability of finding a sequence of 2 nucleotides (e.g. AG) is 1/4 x 1/4 = 1/16.
The probability of finding a sequence of 3 nucleotides (e.g. AGC) is 1/4 x 1/4 x 1/4 = 1/64.
The pattern here is that the probability can be calculated by the probability of finding any particular nucleotide to the power of the length of the sequence. For a 2 nucleotide sequence, the probability is 1/(4)². For a 3 nucleotide sequence, the probability is 1/(4)³, and so on.
This is a 5 nucleotide recognition sequence, so the probability is 1/(4)⁵ = 1/1024.
If the E coli genome is 46 kb, that means there are 46,000 nucleotides. We expect to find this sequence once every 1024 bases:
46,000 ÷ 1024 = 44.92
Therefore, we expect to find this sequence approximately 45 times in the E coli genome.
I believe C because of downstreams but i’m not sure
