The correct answer is: D) H2O… CO2
Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).
Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.
The first step: Oxygen in water is oxidized (light energy required)
The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).
That's called a convex lens, as they converge.

Answer:
When literacy rates goes up then crude birth rates will automatically be decline
Explanation:
Crude birth rate refers to the number of births /1000 in a population. It doesn’t count the age and sex in a population.
General fertility corresponds to number birth of a women age between 15- 49 in a year.
Factors Affecting fertility Rates: Healthcare,Education
Healthcare: Improvement in healthcare leads to drop infant mortality rate , knowledge of birth control measures and economic status have an impact on birth rates.
Education: Female literacy rate and knowledge of birth control and employment opportunities also decline crude birth rate.
