Answer:

b. photosynthesis in which water photolysis produces H , e , and O2 is the correct answer.

Explanation:

  • Cyanobacteria is the oxygenic microbes that produce oxygen by a process called photosynthesis.
  • Photolysis is the process  by which water molecules split into oxygen and hydrogen during the light reaction of the photosynthesis process.
  • Cyanobacteria produce their food by photosynthesis.
  • Cyanobacteria has chlorophyll that converts carbon dioxide to sugar by carbon fixation.
  • Cyanobacteria perform photosynthesis by using carbon dioxide, sunlight, and water to produce oxygen and carbohydrates.
  • Thus cyanobacteria utilize the energy from light to split the water molecule and produces H, e , and O2.

Compare and contrast oceanic crust with continental crust. In your answer, be sure to consider the features of the two types of
Marianna [84]

Answer:

“Crust” describes  the outermost shell of a terrestrial planet. Our planet’s thin, 40-kilometer (25-mile) deep crust—just 1% of Earth’s mass—contains all known life in the universe.

Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Earth’s layers constantly interact with each other, and the crust and upper portion of the mantle are part of a single geologic unit called the lithosphere. The lithosphere’s depth varies, and the Mohorovicic discontinuity (the Moho)—the boundary between the mantle and crust—does not exist at a uniform depth. Isostasy describes the physical, chemical, and mechanical differences between the mantle and crust that allow the crust to “float” on the more malleable mantle. Not all regions of Earth are balanced in isostatic equilibrium. Isostatic equilibrium depends on the density and thickness of the crust, and the dynamic forces at work in the mantle.

Just as the depth of the crust varies, so does its temperature. The upper crust withstands the ambient temperature of the atmosphere or ocean—hot in arid deserts and freezing in ocean trenches. Near the Moho, the temperature of the crust ranges from 200° Celsius (392° Fahrenheit) to 400° Celsius (752° Fahrenheit).
