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.
Answer:
cThey both reproduce by means of seeds.
Explanation:
This is because both flowering plants and conifers reproduce by seeds. Although Conifers are gymnosperms, and angiosperms are flowering plants but conifers grow their seeds naked, it often appear on the scales of a cone, instead of encased in fruit. The flowering plants seeds are encased in fruits. Both conifers and flowering plants are vascular plants that is they have vascular tissues which help them conduct water and nutrients
i. In bright sunlight, the Calvin cycle takes place in the stroma. At the time of the Calvin cycle, the products of the light-dependent reactants, that is, ATP and NADPH are used to transform molecules of carbon dioxide into high-energy sugars.
ii. In the darkness, the Calvin cycle also takes place in the stroma. During the Calvin cycle, the products of the light-dependent reactions, that is, ATP and NADPH are used to transform the molecules of carbon dioxide into high-energy sugars.
iii. If the plant has been kept in dark for an extended period of time, then there may be not enough production of ATP and NADPH taking place in order to continue the Calvin cycle.

Pretty sure it's D. Let me know if it's right or not though
