Using context clues, what does “ferrying its newly-gained energy with it “ mean when talking about convection?
finlep [7]

The term "ferrying its newly-gained energy with it" means that the fluid carries the energy it acquired as it rises during convection.

Convection is a mode of heat transfer in which energy is transferred by the bulk movement of particles from one point to another. During convection, a fluid is heated and its particles acquire energy, These energetic particles now move upwards and are replaced by less dense fluid at a lower energy.

The term ferrying its newly-gained energy with it, implies that the heated particles carry the energy they have gained with them as they rise during convection.

What is the role of glucose in catabolite repression? What is the role of glucose in catabolite repression?
Ierofanga [76]

Answer:

It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.

Explanation:

When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.

Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.

Continuous rotation of the CT x-ray tube and detector array, with simultaneous movement of the CT couch, has been accomplished t
Andrei [34K]

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.
