You would expect an earthworm to have no exoskeleton because as you see it is very flexible and soft. Organisms with such have body parts that are divided and an earthworm do not have any visible parts on them also having an exoskeleton would not allow an organism to move like an earthworm does.
Answer:
Sample 4.
Explanation:
Oxygen is very important for life, so this should be present.
D. There are no major fault lines or hot spots close by.
Why?
Because "They don’t occur anywhere else other than along the Ring of Fire" is incorrect, the Ring of Fire is just a place where many volcanoes are.
Because "The composition of the rock in that area is not conductive to eruptions." they type of rock doesn't play that much of a role in the formation of volcanoes
Because "The magma doesn’t have enough silica or gas to form an explosive eruption." It isn't a gass that is found, it is the build up of pressure from fultlines moving and things on the inside of the earth.

Answer:
Increase in transcription
Explanation:
Transcription is the process of forming RNA from DNA. It can be controlled by many factors like a repressor. Repressor can bind to the operator region of the promoter and hinder the movement of RNA Polymerase enzyme, halting the process.
Here, it is given that the repressor needs to first bind to an effector molecule X. Once it binds to X, it is activated and then it can bind to operator of gene A to inhibit its transcription. If the X binding domain on repressor is mutated it wont be able to bind to X. Thus it wont get activated and wont be able to attach to operator region to inhibit transcription. Hence, transcription process will keep going on uncontrolled.
