Answer:
The correct answer will be option-D
Explanation:
The process of photosynthesis release oxygen from the plant which is used by the organism on earth during cellular respiration.
The oxygen released by the plants is formed through the splitting of water molecules as a result of the transfer of electrons through the electron transport chain in the thylakoid membrane during the light-dependent reaction.
Since the released oxygen is the result of the light-dependent reaction and not the light-independent reaction or Calvin cycle where heavy oxygen isotope is utilized in the cycle.
Thus, option-D is the correct answer.
Answer:
here you go hope it helps you with your question
Explanation:
because nitrogen is required for growth it is considered an essential nitrate so true
converting nitrogen from a gas to a useable form by bacteria is denitrification is true two
the movement of chemicals on a global scale from abiotic through biotic parts of the environment is a lithospheric process true
Molecules move from an area of high concentration to an area of low concentration is F A L S E .
Highly reactive atoms or molecules that can cause damage to cells are called free radicals.
<span>Free radical is an atom, molecule, or ion that has an unpaired valence electron (electron in outermost shell). Because of that, free radicals are very unstable and they react quickly with other substances in order to make up the number of electrons in their outer shell. Free radicals may be generated in many different ways such as redox reactions, ionizing radiation, heat, electrical discharges..</span>
<span>Oxidative stress is a process which happens within the body and it is caused by oxygen free radicals or reactive oxygen species (ROS). Oxidative stress can damage cells, leading to a range of diseases and cause aging.</span>
Enzymes because they are the catalyst of the reaction process.
