Answer:
The greater an object's mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. That's why the moon isn't pulled out of Earth's orbit by the gravity of larger planets or by the sun.
hope this helps
have a good day :)
Explanation:
The answer is; Uracil, Thiamine
The two different structurally, with thymine having a methyl group in its ring structure which uracil lacks. DNA does not have uracil because Cytosine can be tautamerized and deaminate to produce uracil. Uracil is recognized by repair enzyme of DNA, nicked and replaced by cytosine. If uracil were a component of DNA, the repair systems would not be able to distinguish original uracil from uracil originated by deamination of cytosine. Thymine is more stable than uracil, a requirement for DNA which stores critical cell information.
