China MCQs

Selection favours resistant variants, while transmission and gene exchange can spread resistance.

Adaptive responses integrate receptor specificity with co-stimulatory and environmental signals.

Larger samples reduce random error but do not necessarily correct systematic design or measurement problems.

Passive transport is driven by concentration and electrical gradients, although channels or carriers may facilitate it.

Cardiac output integrates rate and stroke volume, while loading conditions and contractility influence stroke volume.

Respiratory and renal responses limit pH change while the primary process remains identifiable.

Multiple mediators act on vessels, cells and tissues to produce the organised inflammatory response.

Multiple mediators act on vessels, cells and tissues to produce the organised inflammatory response.

Tumorigenesis is multistep and reflects genetic, epigenetic and microenvironmental selection.

Selection favours resistant variants, while transmission and gene exchange can spread resistance.

Adaptive responses integrate receptor specificity with co-stimulatory and environmental signals.
