Answer:
There is no short answer.
Explanation:
Gravitational attraction depends on two factors, the mass of the objects and the distance between them.
In the example given in the question, the gravitational attraction to the moon would be much higher than the gravitational attraction to the cat because of the big mass difference between them even though the cat is closer to Tina.
I hope this answer helps.
Explanation:
The discoveries indicates that the rocks were formed over millions of years ago due to the age of fossils they contain.
Fossils are the preserved remains of life found in rocks. Most fossils are used in relative dating of rocks.
- Dinosaurs are extinct organisms that once lived in the Mesozoic. This was about 100 million years ago.
- Tool man also grazed the surface of the earth just a few thousands to a million years.
- We are able to find their fossils in rocks because they have lived in some certain geologic periods.
- Here we are using the fossils to date the rock and this is called relative dating

Answer:
Explanation:
The above mentioned key points are mechanisms by which cells used to correct replication error and repair damaged DNA.
Proof Reading: while printing a page, the typesetter set the types and impression is taken, proof reading is done to correct mistakes if any, and the final printing is done. A similar follow up mechanism is done after DNA synthesis. If DNA polymerase detects an incorrect nucleotide pair, it will remove and replace with the correct nucleotide immediately.
Mismatch Repair:even after DNA synthesis, mismatch area(insertion or deletion) can be identified on the newly synthesized DNA.
In the mismatch repair, specific proteins scan the newly synthesized DNA strand. The mismatch area is identified and loop.
The second protein complex remove the mismatch segment. Finally correct segment is synthesized by the help of DNA polymerase, SSBs and ligase.
DNA damage repair mechanism: when DNA get damaged, there's a repair process that fix the damage. This includes Direct reversal, excision repair and Double stranded break repair
