Answer:

<em>The correct option is D) oxygen</em>

Explanation:

The splitting of the water molecules during the light-dependent reactions results in the production of 2 electrons, two hydrogen ions and the formation of oxygen gas. The electrons released by this process make ATP by a process which is known as chemiosmosis. The hydrogen ions released during the light-dependent reactions are converted into NADPH during the light-independent reactions. Oxygen is the by-product and is released into the air. The oxygen is used up by other organisms of the earth for cellular respiration.

Option 3, of the abiotic factors found in their environment

Explanation:

The abiotic factors such as absence of sunlight and extremely cold temperature represents picture of an extreme habitat under an ice shelf in Antarctica.  

The optimum temperature requirements of bacteria for its survival ranges from 10oC to 20oC. In case,  if a bacteria lives in an environment where temperature is less than -5oC or higher than  50oC, then such habitats are considered to be “habitats with extremities”  as special physiological mechanisms are required to maintain the homeostasis and survive.

Likewise absence of sunlight further adds to the extremities of the habitat.

Montano1993 [528]

Answer:

Explanation:

Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.

Good luck!!
