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

Conditioning
<h3><u>Explanation;</u></h3>
- This was an example of classical conditioning. Classical conditioning is when two stimuli are linked together to produce a new learned response in a person or an animal.
- <em><u>An experiment done by Pavlov demonstrated classical conditioning in dogs. Such that; there was a neutral stimulus (the bell), which by itself will not produce a response, like salivation and also there was a non-neutral or unconditioned stimulus (the food), which will produce an unconditioned response.</u></em>
