The Van Allen belts are created by a planet's magnetic field. Therefore C. Earth's magnetosphere is the correct answer
Answer:
The options
A. Additional cables
B. Slip rings
C. Multiple rows of detectors
D. Electron beam CT.
The CORRECT ANSWER IS B.
B. Slip rings
Explanation:
During the 1990s, the use of slip ring technology promoted consecutive rotation of the x-ray tube (via removal of cables) and concurrent couch locomotion.
The Sixth-generation CT scanning is referred to as helical (or spiral) CT—allowing procurement of volume multislice scanning.
Today's helical multislice scanners, makes use of thousands of detectors (around 60+ rows), can derive continuous data procurement of 128 "slices" per tube rotation and can undergo 3D multiplanar reformation (MPR).
Fifth-generation CT employs electron beam; as the ultra high-speed CT is employed majorly for cardiac imaging.
Answer:
The gene that encodes ampicillin resistance.
Explanation:
The plasmid would contain the ampicillin resistance gene which gets expressed in the presence of ampicillin.
If you do not have variations to be selected by natural or sexual selection on their superior abilities to survive and reproduce successfully then nothing can be naturally selected against the immediate environment.
