Answer: 4 Guanines
Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.
We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
I believe that would be a cell from a plant
Answer:
The correct answer is B.
Explanation:
The answer is partly in the name of the theory. The Endosymbiotic Theory, endo meaning "to absorb" or "to contain" and symbiotic meaning "a mutually relationship between two bodies in which both mutully benefit from" or "close physical interaction between two organisms".
The theory suggests that at some point in time, a prokaryotic cell was consumed by another cell which eventually led to the development of organelles such as mitochondria and chloroplast. The strongest evidence for this statement is the fact that these organelles have their own DNA, which can be an indication to the fact that once they were seperate organisms.
I hope this answer helps.
A injury to the spinal cord. It stops the signals from your brain traveling to your nerve to move. So a break in your spine would cause the permanent loss or simple reflexes.
