1. Two genetically identical copies of DNA
2. Finds an error in DNA, removes the incorrect nucleotide and replaces it with a correct one.
3. It is used as a copy/ "template" for replication in order to have two identical copies of DNA.
4. DNA helicase unwinds DNA double helix and Topiosomerase ensure there isn't too much unwinding.
5. Replication has a built on proofreading system - DNA polymerase removes the incorrect nucleotide and replaces it with a correct one.
Answer by Mimiwhatsup: Divergent Boundaries. Tectonic plates will slowly move away from the other, the heat from the mantles convection current will crust the plastic making it much way less dense and the less dense material will rise up and will often form a mountain or elevated area of the seafloor.
In the above food web green algae is the producer, periwinkle and microscopic animals are primary consumers; mussel, barnacle, dogwhelk and crab are secondary consumers; dogwhelk and crab comes under tertiary consumer; dogfish is a quaternary consumer.
What is a food web?
It is a natural interconnection of several food chains in a single ecosystem. Each food chain supplies energy and nutrients through the ecosystem. There are four food webs producer, herbivores, carnivores, omnivores and decomposers.
Here green algae comes under autotrophs(prepares their own food), periwinkle and microscopic animals are herbivores(depend on producer); mussel, barnacle, dogwhelk and crab are carnivores(depend on herbivore); dogfish is an omnivore(depends on both producer and carnivore).

Answer:
the time that cell spend in prophase is 30 minutes
Explanation:
The computation is shown below:
= Number of cell ÷ sample
= 25 ÷ 100
= 1 ÷ 4
Now it takes two hours
So,
= 1 ÷ 4 × 2 hours
= 0.5
This 0.5 represent the 30 minutes
Hence, the time that cell spend in prophase is 30 minutes
