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).
A phenomenon, in the scientific context, is an observable event that can range from a seasonal hazard to a technological issue. For a scientist, a phenomenon is an observable event.
They also need energy to move and to stay alive
It looks correct to me. Good job
Asystole is defined as a cardiac arrest rhythm in which there is no discernible electrical activity on the ECG monitor. Asystole is sometimes referred to as a “flat line.” Confirmation that a “flat line” is truly asystole is an important step in the ACLS protocol.
