rewona [7]

Answer:

The process illustrated in the diagram is the non light dependent reactions of photosynthesis termed as Calvin Cycle.

Explanation:

  • Two molecules of 3-phosphoglycerate (3-PGA) are produced or released from step one to step two of Calvin cycle.
  • The source of energy that helps to start step one are ATP and NADPH, mainly derived from the light dependent reaction.
  • The oxygen molecule thus formed by splitting of water is release to the nature as oxygen, which living organisms utilizes in respiration.
  • Carbon dioxide comes from the atmosphere to start the process.
  • Light reactions occurs in the thylakoid membranes of the plant organelles namely chloroplasts.
  • Non-light dependent reaction or Calvin cycle takes place in the stroma chloroplasts.

What can you do to play an active role in cancer prevention?
melisa1 [442]

Answer: Although humans cannot prevent all cancers, a healthy diet and weight followed by adequate exercise, sleep, and stress reduction all play a part in cancer reduction.

Cancer occurs when cells multiply uncontrollably and are not "cleaned up" by the body. We are dependent on our bodies recognizing and destroying old cells and foreign substances like toxins. When our body's fail to do this, either through stress, poor diet or being sedentary, cancer could result.

Hope this helps.
