Where is the data?
Your teacher must’ve gave you
The soda contains CO2 that is dissolved CO2 reacts with water
CO2+H2O--->H2CO3
to form carbonic acid
this is a weak acid but it gives protons to water
H2CO3+H2O-->-HCO3+H30+
pH=-lg[H3O+]
[H3O+] is the molar concentration
Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.
The S wave penetrate the interior of he earth
shake the ground perpendicular to the direction in which they are propageting.
It does not travel through liquids.
1.7 times slower than P waves
Answer: Self-replicating RNA
RNA can do catalytic functions like enzymes. It carries genetic information and replicate itself. It also carries information about vesicles which carries it. RNA is less stable than DNA which confirms that genetic material is evolved from a less stable to highly stable form.
Abiotic: soil,sunlight, Thunderstorms, earthquake, temperature
Biotic: Competition, disease, prey symbiosis, water table
