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
The diversity of species and genes in ecological communities affects the functioning of these communities. and that is all i know
Answer:
"Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones."

Does this help?
No problem
so
Chain 1. Sun -> Tomato plant -> Tomato -> You
The sun provides energy to the tomato plant which is used to grow a tomato which is eaten by you.
Chain 2. Sun -> Wheat -> Flour -> Bun -> You
The wheat uses the sun's energy to grow when the wheat is mature it is used to produce flour which is used to bake the buns for the hamburger which is then eaten by you again.
Chain 3. Sun -> Lettuce -> You
The lettuce grows and uses the sun's energy to live it is then eaten by you in the hamburger.
Hope this helps :).
