Answer:
C. Diffusion and no energy needed.
Explanation:
A - Passive transport doesn't require energy.
B - Osmosis would be if the 25% H2O went into the 82%
D - Active transport doesn't apply because molecules aren't moving across into a higher concentration.
Diffusion is when parts of the 82% go into the 25%.
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.

Explanation:
Almost all eukaryotic proteins are subject to post-translational modifications during mitosis and cell cycle, and in particular, reversible phosphorylation being a key event. The recent use of high-throughput experimental analyses has revealed that more than 70% of all eukaryotic proteins are regulated by phosphorylation; however, the mechanism of dephosphorylation, counteracting phosphorylation, is relatively unknown. Recent discoveries have shown that many of the protein phosphatases are involved in the temporal and spatial control of mitotic events, such as mitotic entry, mitotic spindle assembly, chromosome architecture changes and cohesion, and mitotic exit. This implies that certain phosphatases are tightly regulated for timely dephosphorylation of key mitotic phosphoproteins and are essential for the control of various mitotic processes. This review describes the physiological and pathological roles of mitotic phosphatases, as well as the versatile role of various protein phosphatases in several mitotic events.
