"The oxytocin in blood stimulates the pituitary to secrete more oxytocin" is the way among the following choices given in the question that <span>the level of oxytocin is controlled by a positive-feedback mechanism. The correct option among all the options that are given in the question is the second option or option "B".</span>
Answer:
The correct answer is -
Thymine: 20%
Guanine: 30%
Cytosine: 30%
Explanation:
According to Chargaff's rule which states that the purine residues are equal to the pyrimidines residue in DNA sample which means A+G = T+C where A is adenine, G is guanine, C is cytosine and T is thymine. It is also known that A is always equal to T and C is equal to G.
So, A+G+T+C = 100
20+20+G+C
100-40 = G+C
60= G+C
as we know G is equal to C similarly A is equal to T
Thus, G = C= 30%
A= T= 20%
Plants obtain energy through a process called Photosynthesis, in which the plant takes the suns's energy through the Chlorophyll, which is what makes plants green, and uses it to make sugars out of the carbon dioxide from the air and water.
