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.
Water is a basic need for every organism
Alcohol gives you energy is not true about alcohol. So, the correct option is (c).
As a depressive, alcohol can upset this equilibrium and have an impact on our emotions, thoughts, and behaviour. This is due in part to neurotransmitters, which are molecules that aid in signal transmission from one brain nerve to another.
Your coordination will be impaired by alcohol since it will require more mental effort to cause your muscles to obey directions. Your brain needs more time to see, comprehend, relate to, and decide how to respond to something when you drink alcohol. Alcohol has an impact on almost every organ system in our body.
Therefore, Alcohol gives you energy is not true about alcohol. So, the correct option is (c).

Answer:
Two adaptations of Darwin's Finches that helped them to survive are:
- Behavioral adaptations to use tools for foraging.
Explanation:
There are fourteen species of Darwin's finches that originated from a single species of ground dwelling seed eating finch.
These Finches occupied different niche in the Galapagos island and were widely studied by Darwin.
These finches are one of the best Examples of Adaptive radiation.
Studies state that during severe drought in Galapagos island most vegetation dried out and a few softer seeds were left.
These few seeds were quickly fed upon by the birds and only dry , hard seeds were left.
Only birds who had large and hard beaks could feed on these hard dry seeds.
To Ensure survival the Finches developed adaptations which resulted in hard and large beaks so that they can feed on those dried hard seed.
Some groups started feeding on insects and got their beaks adapted to capture and kill insects.
Second line of adaptation included changes in behaviour and cognitive intelligence where birds started using tools for foraging.
