Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. To determine this, he uses an isotope of oxygen called O-18. He labels the O-18 oxygen so he can follow its path through photosynthesis. Plant A is given carbon dioxide that contains the O-18 isotope. Plant B is given water that contains the O-18 isotope. When he examines the oxygen from both plants, only plant B produced O-18 oxygen. This indicates that the source of oxygen is water. The photosynthesis involves the transfer of electrons between the photosystem I and II. The water gets split into oxygen, hydrogen ions and electrons in the photosystem I. The electrons move to the photosystem II where the carbon fixation into sugars takes place. The plant A will have O-18 isotope in its synthesised sugar molecule, which gets stored inside it.
Answer:
Increases homocysteine levels
Explanation:
Homocysteine is an aminoacid that is resent in our blood already. This is mostly increased in our blood due to increased consumption of meat and other potential reasons, such as smoking.
High level of this aminoacid are linked to the development of heart diseases. This is because a high homocysteine level causes development of heart diseases along with other risks of renerl diseases.
