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).
Cells are combined in a structure called tissue wich have the same properties like the cells wich are formed by.
Spongy bone has trabecular which serve as reinforcing plates against a force. The loss of spongy bones causes weakening of the internal support that the compact bone requires and the entire bone breaks.
The correct option is D.
Sexual form of reproduction leads to increased genetic diversity as a result of the two different reproductive cells that are coming together and the biological assortment that occur during the process of cell division. Increased genetic diversity enhance variations among living organisms and increased their potentials to survive in their environments.
