Answer:
The model of the DNA can be related to a zipper. Just like the zipper, the two strands of the DNA are joined together by the hydrogen bonds present between the nucleotides. At the time of replication, the coiling of the two strands is undone just as the zipper is open. The two strands of the DNA open and separate just as the two stands of the zipper open and separate. Each strand can give rise to anew strand.
Just as the opening and closing of the zipper can cause damages in the zipper, just like this replication can cause errors in the DNA which lead to mutations.

Hope this helps!
Answer:
Explanation:
1. From the atmosphere. The CO2 found in the atmosphere including ones expelled by animals during respiration is used in photosynthesis
2. From sunlight. During photosynthesis, plants utilize energy from the sun also known as solar energy converting it into chemical energy
3. The product which is glucose is metabolized in the mitochondria
4. The reduction of CO2 with it acting as an electron acceptor
5. Oxygen is a waste product of oxygenic photosynthesis wherein with oxidation of water, oxygen is produced as a byproduct
