It happens because of Point mutation
Explanation:
A point mutation can be understood as when one nucleotide is added, deleted or changed. Through change in DNA structure a gene can be altered and it is called mutation. Point mutation’s other term is insertion as well as deletion. It mostly involves in substitution.
Rarely, Point mutation is responsible for huge change. Basically, two types of point mutation happen. They are transition or transversion mutations.

CO₂ is the waste product of respiration of cells. Oxygen, on the other hand, is required in cellular respiration. Therefore at the alveolar in the lungs of an organism, CO₂ will be expelled while O₂ will be taken in.
Explanation:
This occurs passively due to the diffusion gradient, CO₂ usually has a higher concentration in the blood and lower concentration in alveoli hence this gas diffuses from the bloodstream into the lungs. On the other hand, oxygen is higher in concentration in the alveoli than in the blood capillaries hence difuses into the blood and taken to the cell for respiration. The CO₂ in the lungs is then expelled through exhalation of the lungs.

We produce carbon dioxide, plants take it in for photosynthesis.
-
The beginning products (plants take these in to start photosynthesis) are h2o and co2
(Water and carbon dioxide )
-
So you could say carbon dioxide is a beginning product in photosynthesis.
Hope this helps!
Answer:
Welcome to the promised follow-up to our previous examination of the digital television revolution. This week we finally take an opportunity for tortured reference to the revolution being digitized. I suppose everyone is probably making that joke. You heard it here last.
To recap the situation as seen from television-free floor 2B: there are around 275 million TVs in the U.S. These historically were cathode-ray sets receiving analog signals. All stations are to convert to digital signal by mid-June, hastening the obsolescence of analog-only CRTs, the sale of digital converter sets, and the potential change to LCD, plasma, or rear-projection televisions. Last time we learned that CRT recycling is possible and urgent, that Energy Star certifies digital converter boxes, and that Umbra thinks Jon Stewart is cute. Luckily for me I can watch his digital likeness over the internets.
