Answer: Option D) 1:4
Explanation:
Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.
So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.
Now, A + T + C + G = 100%
So, if adenine makes up 10% of the DNA nucleotides, then thymine is also 10%.
Then, 10% + 10% + C + G = 100%
20% + C + G = 100%
C + G = 100% - 20% = 80%
Thus, divide 80% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 40%
Ratio Adenine to Guanine is 10% to 40%
or 1:4 in simplest form

Answer:
The answer is positive interference
Explanation:
There are many human activities that have aggravated the planet through the phenomena of global warming. However, the biggest contributor to global warming is human use of fossil fuels and the resulting emissions from this use. The use of automobiles, factories, and other fossil fuel burning activities have led to a dramatic increase in greenhouse gases in the atmosphere which has led to global warming.
Answer:
The correct answer:
1. 100 × 35/100 ⇒ 35% of 100 (2nd and 7th)
2. 200 × 25/100 ⇒ 25% of 200 (4th and sixth)
Explanation:
As it is given that and we know that 25% of 200 can be calculated by multiplying the principle value which is 200 to percentage value divided by 100 (100 is whole value).
Similarly, we can found the calculative representation of 25% of 200 and 35% of 100 are only two values that can be put in boxes after the arrow that are:
1. 100 × 35/100 ⇒ 35% of 100
2. 200 × 25/100 ⇒ 25% of 200
