In 2005, a new species of green sulfur bacteria was discovered near a geothermal vent at the bottom of the ocean. an exceptionally efficient light-harvesting mechanism allows these bacteria to carry out photosynthesis where the only illumination is a dim volcanic glow emanating from the vent. cell membranes are required for electron transfer chains in the light-dependent reactions, but these bacteria have no internal membranes. how do you think they carry out the light-dependent reactions?

Photosynthetic

Explanation:

Photosynthetic bacteria may be able to live without solar light, instead using thermal radiation from hot fluid for energy, according to a study in this week's PNAS. Researchers led by J. Thomas Beatty of the University of British Columbia, Vancouver, have found obligately photosynthetic green sulfur bacteria at a deep-sea hydrothermal vent more than a mile below the ocean surface.

a: the sheep and waste material both release carbon into the atmosphere.

type 2 happens when excess consumption of high-sugar foods flood the blood supply with glucose and reduce the production and effectiveness of insulin. if a person has prediabetes, they can reduce the risk of full diabetes through regular exercise and a balanced, low-sugar diet.
