Explanation:

1.Oxygen is evolved when

Oxygen evolution is the process of generating molecular oxygen (O2) by a chemical reaction, usually from water. Oxygen evolution from water is effected by oxygenic photosynthesis, electrolysis of water, and thermal decomposition of various oxides.

2.In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP+, respectively.

3.The series of biochemical redox reactions which take place in the stroma are collectively called the Calvin cycle or light-independent reactions.

3.Photosynthesis happens in two steps. In the first step, the light reaction, chlorophyll in the grana absorbs light. The light's energy is transferred through a series of enzymes in the thylakoid membrane, resulting in the production of two energy-carrying compounds: ATP and NADPH.

4.Cellular Respiration: Glycolysis is the first pathway of cellular respiration that oxidizes glucose molecules. It is followed by the Krebs cycle and oxidative phosphorylation to produce ATP.

answer: although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. a cold virus enters your body through your mouth, eyes or nose. the virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. theres your answer
