DNA sequence can be altered by the process called as mutation. Mutation of DNA sequence can have a positive or negative effect on an organism and it entirely depends on the point and type of mutation that has occurred on the DNA sequences.

Mutations can be point mutation where single nucleotide base gets altered or deletion where a base pair gets deleted from the DNA sequences and many more. Mutation has driven the evolution of the organism.

Soda and other carbonated beverages seem more "fizzy" when they are served on an airplane at standard cruising altitude. Write a

Katyanochek1 [597]

Answer: the low air pressure reducing CO2 solubility

The differences between the airplane and standard cruising altitude are air pressure. When you are on the higher ground, the air pressure should be lower since there is less air above your head.
In a place with less air pressure, the gas solubility will decrease. Bubbles appeared if gas solubility is lower than the gas concentration. Assuming the beverage concentration is same, then it will be much more bubble appeared in an airplane because the gas solubility is lower.
