Correctly match the herbicide with its mode of development of resistance in plants.


 

The output \( y(t) \) of a first-order process is governed by the following differential equation: \[ \tau_p \frac{dy}{dt} + y = K_p f(t) \] where \( \tau_p \) is a non-zero time constant, \( K_p \) is the gain, and \( f(t) \) is the input with \( f(0) = 0 \). Assume \( y(0) = 0 \). The transfer function for this process is (consider \( s \) as the independent variable in the Laplace domain).
A thermometer measuring body temperature follows a first-order response with a time constant of 40 seconds. The instrument will reach 95% of its steady-state output at __ seconds.
The allele associated with albinism in humans is recessive (c). The probability that an albino male (cc) and a carrier female (Cc) will have an offspring with normal skin pigmentation is _________.

Which one of the following hosts is used in mammalian cell culture for the production of glycosylated recombinant therapeutic proteins?
Which one of the following is true for piRNAs?
Which of the following enzymes is/are involved in the biogenesis of miRNA?
A cultured skin fibroblast cell of a goat ‘P’ was fused with an enucleated ovum of a goat 'Q'. The resultant activated early embryo was then transplanted into a pseudopregnant (surrogate) female goat 'R' of the same strain as 'Q'. On completion of gestation, a female goat 'S' was born. With the exception of mitochondrial DNA, 'S' is a clone of
