An oil spill from a tanker is an example of point-source pollution.
I believe it is DNA: deoxyribonucleic acid
It would be slightly worse than taking it off in space. The atmosphere on the surface of Mars is nearly a vacuum, so the astronaut would do well to notice the boiling saliva and tears and reseal the helmet immediately. Failing that, he or she would pass out in a few seconds, which is perhaps just as well. In space, you can only cool off by evaporation or by radiating infrared into space. On Mars, the tenuous air is just barely thick enough to conduct heat, and it’s generally colder than northern Siberia in the January. So…yeah. Don’t do that.
I would say medicine that makes the immune system less effective so the likelihood of the immune system attaching the organ are decreased. Or the last option.
Answer:
Light-dependent reaction of the photosynthesis takes place in the thyllakoid membrane of the chloroplast. It converts solar energy into the chemical energy (ATP and NADPH) which is then utilized in the light-independent reaction to fix carbon into glucose or food.
The correct order of events that take place during light-dependent reaction would be:
Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.
↓
Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space.
↓
The concentration of hydrogen ions in the thylakoid space increases.
↓
Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.
↓
ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.
