If for some reason our goblet cells are non-functional,this will adversely affect:

$A$ man of mass $m$ starts falling towards a planet of mass $M$ and radius $R$. As he reaches near to the surface,he realizes that he will pass through a small hole in the planet. As he enters the hole,he sees that the planet is really made of two pieces: a spherical shell of negligible thickness of mass $2M/3$ and a point mass $M/3$ at the centre. What is the change in the force of gravity experienced by the man?

If $\frac{x-4}{x^2-5x+6}$ can be expanded in the ascending powers of $x$,then the coefficient of $x^3$ is

What is the function of the spleen in humans?

The set of all points for which $f(x) = x^2 \cdot e^{-x}$ strictly increases is

For a binomial variate $X$ with $n=6$, if $P(X=2)=9 P(X=4)$, then its variance is
