Question 1 (1 point)
The image below represents a bacterium. Which of the following best describes a
feature shown in the diagram that is unique to archaea and bacteria?
4
5
6
The organism does not have a nuclear membrane surrounding its genetic
material,
The organism is surrounded by a cell wall.
The organism is not capable of making or providing itself with ATP.
The organism contains ribosomes.

this process is called "phosphorylation." a phosphate bond joins adenosine diphosphate to form adenosine triphosphate.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.

bacterium is not correct
