In Neurospora, the mutant stp exhibits erratic stop-and start growth. When a female of stp strain is crossed with a normal strain acting as a male, all progeny individuals' showed stp mutant phenotype. However, the reciprocal cross resulted in all normal progeny, individuals. These results can be explained on the basis of

A. Uniparental gene contribution

B. Nuclear inheritance with concept of dominance

C. Sex link character

D. stp mutation may be located in chloroplast DNA

The most appropriate statement or combination of the above statements for explaining the experimental results is:

Listed below are the hydrostatic and oncotic pressures and filtration rate across a muscle capillary wall:

Capillary hydrostatic pressure (Pc) = 25 mm Hg

Plasma colloid osmotic pressure (Πp) = 25 mm Hg

Interstitial colloid osmotic pressure (ΠI) = 10 mm Hg

Interstitial hydrostatic pressure (PI) = −5 mm Hg

Capillary filtration rate = 150 ml/min

What is the capillary filtration coefficient?

Listed below are the hydrostatic and oncotic pressures within a microcirculatory bed:

Plasma colloid osmotic pressure = 25 mm Hg

Capillary hydrostatic pressure = 25 mm Hg

Venous hydrostatic pressure = 5 mm Hg

Arterial pressure = 80 mm Hg

Interstitial fluid hydrostatic pressure = −5 mm Hg
