2. If 10% of the bases in a molecule of DNA are adenine, what is the ratio of adenine to guanine in the same
sertanlavr [38]

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

What are some reasons why common names are insufficient for naming animals? answer in a short paragraph form and include at leas
lana66690 [7]

Answer:

Scientific names of animals use both the genus and species name, which is much more specific than common names, and gives more information.

For example, using the name cat just tells us that the animal is a cat

however, the scientific name felis catus, tells us that the species is catus and the genus is felis
