The options for this question are not provided hence, I found the answer on the internet.
Phrase to describe the electron transport chain in photosynthesis is:
IT IS A SERIES OF PROTEINS LOCATED IN THE THYLAKOID MEMBRANE OF THE CHLOROPLAST.
ATP synthase enzyme that facilitates electron transport chain in eukaryotic cells. It is present in the inner membrane of mitochondria and in the thylakoid of chloroplast.
Answer:
I believe it is the burning of fossil fuels.
Explanation:
The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis.
The cycle of carbon is carbon is moved through the atmosphere (carbon dioxide) to organisms. It is then moved from one organism to the next in complex molecules. Next, it is brought back to the atmosphere as carbon dioxide again.
Simple explanation is carbon passed through the atmosphere and back to animals and plants.
Most cases of Prader-Willi syndrome are not inherited, particularly those caused by a deletion in the paternal chromosome 15 or by maternal uniparental<span> disomy. These genetic changes occur as random events during the formation of reproductive cells (eggs and sperm) or in early </span>embryonic<span> development.</span>
