Answer:

False. The driving for is the partial pressure gradient of O2 (PO2 difference), not the PCO2 gradient.

However, keep in mind that an increase in PCO2 can facilitate the unbinding of oxygen from hemoglobin. This is due to a decrease in pH associated with PCO2 increase. The H+ ions bind to hemoglobin and decrease it's affinity for oxygen, this is called the bohr effect. But the PCO2 is not the main driving force of oxygen unbinding.

Answer:

The correct answer is fungi.

Fungi are the eukaryotic organism but they can be present in unicellular and multicellular form. They are different from plant, animals, and bacteria. They are heterotrophic organisms and do not conduct photosynthesis. Their cell wall is made up of chitin.  

Most of the fungi are saprophytes which means they take their nutrition from the dead and decaying organism. So fungi play an important role in clearing the waste organic material from the environment so they help in bioremediation. All members of fungi comes under a separate kingdom fungi.

dlinn [17]

The formation of the Hawaiian Islands.

Explanation:

A modern process that is believed to be similar to the way crusts formed before the advent of plate tectonics about million of years ago is the formation of the Hawaiian Islands.

The Hawaiian Island is a series of volcanic Island which forms as result of volcanic activities on the oceanic plate.

  • Hawaiian Islands forms from a hotspot that supplies the ocean floor with sufficient magma as it rides.
  • This is similar to the volcanic activities that initially sculpted the surface of the earth.
  • During the early history of the earth, our very hot and restless planet poured out lava to the surface through which the crust formed.
