Despite being multicellular,its cells are not organized into tissues.

If $dx + dy = (x + y)(dx - dy)$,then $\log(x + y)$ is equal to

Anoxygenic photosynthesis is characteristic of

The energy-releasing metabolic process in which substrate is oxidized without an external electron acceptor is called:

If $x-y+1=0$ meets the circle $x^2+y^2+y-1=0$ at $A$ and $B$,then the equation of the circle with $AB$ as diameter is

Magnetic induction at the centre of a circular loop of area $\pi \ m^2$ is $0.1 \ T$. The magnetic moment of the loop is ( $\mu_0 = \text{permeability of air}$ ).
